Can you install a check valve horizontally?
You can install a check valve both horizontally and vertically. However, when it comes to sump pump systems, vertical installation is the way to go. Besides, municipal law in many states prohibits the horizontal installation of sump pump check valves.
Can check valves be installed vertically?
We hear many people ask, “Can swing check valves be installed vertically?” The simple answer to that question is yes, swing check valves can be installed in both directions. But to be very clear, installing a swing check valve on a horizontal pipeline can actually look like the valve is vertical.
How do you check PCV valves?

- Remove the valve. Some PCV valves are held in place with a rubber grommet and can just be pulled free. ...
- Check the hose and the hose clamps or grommet. ...
- Screw in the new valve. ...
- Reconnect the hose to the PCV valve. ...
How to check and adjust valves?
Check all 4 valves on #1, the intake valves on #2, and the exhaust valves on #3. For each valve needing adjustment, remove the shim, measure it, make a note, and put it back in. NEVER TURN THE ENGINE WITH A SHIM OUT. Okay, next rotate the engine (clockwise only) 360 degrees (the cam rotates 180 degrees).

Does it matter if a check valve is horizontal or vertical?
When installing a check valve, a horizontal line is always preferred, because it takes gravity out of the equation.
Can we install check valve vertically?
We hear many people ask, “Can swing check valves be installed vertically?” The simple answer to that question is yes, swing check valves can be installed in both directions.
Can a double check valve be installed vertical?
If installed in a vertical configuration, it must be a minimum of 6 inches from floor, and no higher than 5 feet to the centerline of the #2 shut-off valve. All assemblies must maintain a sufficient clearance from any wall, and 24 inches in front of assembly to ensure accessibility for maintenance and testing.
Can a backflow valve be installed vertically?
Backflow preventers can be mounted horizontally, vertically (up or down), or in other configurations to facilitate installation.
What is a vertical check valve?
Vertical check valves are also known as spring check valves since a spring is used to keep the disc against the seat. The valve is held shut by the spring until a sufficient amount of pressure is applied to push the spring back and open the valve. Pressure keeps the valve open and the spring compressed.
What is the best orientation to install a swing check valve?
“A swing check is only supposed to be installed in a horizontal-flow position.
Can I use a check valve instead of a backflow preventer?
check valves. And we clear up a misconception that's often inquired about in online forums: while check valves have other important applications, they cannot be considered a safe substitute for backflow preventers when it comes to protecting the purity of drinking water.
Does a check valve go before or after a pump?
On booster pump applications, a check valve can be placed on the suction or discharge of a centrifugal pump. If an additional check valve is required, it should be placed after the pressure tank to allow the pump and discharge pipe to remain pressurized.
Where should double check valves be installed?
The Double Check Valve must be installed prior to the irrigation system and after the water meter. 2.1. Place the Double Check Valve within 2 feet of the meter box, (See note 5.1 below).
Where should a backflow preventer check valve be installed?
You should have your backflow prevention assembly installed inside an above-ground enclosure. It's the safest and most cost-effective place to put it. Installing your backflow preventer above ground in an outdoor enclosure allows you to protect your backflow preventer and maintain easy access to it.
Can a ball check valve be installed horizontally?
The principle of the ball check valve is very simple. The ball has sufficient weight to seat tightly even in high viscous liquid, but to open freely so that the headloss is minimal. Flomatic ball check valves can be installed horizontally or vertically provided that they are installed as the illustration shows.
How far from pump should check valve be?
In submersible pump applications, the first check valve should be installed directly on the discharge head of the pump or maximum one pipe length (20 feet) above pump.
Can a ball check valve be installed horizontally?
The principle of the ball check valve is very simple. The ball has sufficient weight to seat tightly even in high viscous liquid, but to open freely so that the headloss is minimal. Flomatic ball check valves can be installed horizontally or vertically provided that they are installed as the illustration shows.
Where do you install a check valve?
Another instruction from the bronze pressure reducing valve manufacturers is that the check valve must be installed at the outlet of the pump and in front of the outlet control valve for maintenance.
Which way should the arrow point on a check valve?
The check valve should point in the direction of the gas flow. Using your reference points, you want the check valve arrow to be pointing "up."
Does a check valve go before or after a pump?
On booster pump applications, a check valve can be placed on the suction or discharge of a centrifugal pump. If an additional check valve is required, it should be placed after the pressure tank to allow the pump and discharge pipe to remain pressurized.
Check valve installation procedure - Valve engineering - Eng-Tips
Dear All, We all know that check valves should be installed at least 3 x DN behind the discharge of pumps, not on 90° ellbows, at least 2 x DN before any downstream valve, etc.
How to Install Swing Check Valves - Vertically or Horizontally
Swing check valves are a necessary part of any pipeline where the flow can only go in one direction. In your home, plumbing is a perfect example--unless you want the water that you flush coming back through your faucet! This is a relatively easy process as long as you know a few important details, like how to install swing check valves vertically or horizontally and maintaining your valve ...
Can a spring check valve be installed horizontally? - Quora
Answer (1 of 6): Generally, yes. The spring is there to keep the valve seated and closed during low or no flow conditions. It is better to install it vertically with the flow going downward to keep moisture and debris from sitting on top of the flapper / spring system. That being said it is best ...
Why do check valves need horizontal lines?
When installing a check valve, a horizontal line is always preferred, because it takes gravity out of the equation. However, in real-world applications, the ideal situation is not always available. There are numerous applications where vertical runs are needed to move fluids either vertically up or down – such as within buildings, mine shafts, ...
Why do you need to close an axial flow valve?
The stronger spring of the axial flow valve will ensure that the valve closes before any reverse flow happens. Closing the valve before flow reverses will also eliminate most water hammer, which is the primary advantage of axial flow check valves.
What is the most difficult flow direction to address?
The most difficult flow direction to address is vertical flow down. This flow direction is most often found in boiler supply lines and mining applications, where space is limited. A swing check valve will not work in this position as it will always be open and not doing its job.
Do check valves work vertically?
There are many different requirements when designing fluid flow systems and installing the correct check valves for the application. Not all styles of check valves function properly or are suitable for vertical flow directions. When installing a check valve, a horizontal line is always preferred, because it takes gravity out of the equation.
Can DFT be used vertically?
Whether it is used vertically or horizontally, DFT® can custom size a check valve to the unique requirements of your application. Given the known specifications of fluid type, specific gravity, pressure, flow rate, temperature, and more, we can custom engineer the check valve to suit your application.
Do axial flow valves work in vertical piping?
Only axial flow silent check valves perform well in vertical piping locations, as these valves rely on potential energy from a spring to close rather than on water pressure. This means that the valve will close on its own before any backed-up fluid can force its way back up into the piping.
What is a swing check valve?

In your home, plumbing is a perfect example--unless you want the water that you flush coming back through your faucet! This is a relatively easy process as long as you know a few important details, like how to install swing check valves vertically ...
What happens if something gets stuck in a swing check valve?
If something small made its way into the swing check valve, it could potentially cause the flap to get stuck and prevent all water from flowing. This is a quick and easy step that could save you hours of time and frustration.
How to measure a swing valve?
1. Check Valve Size. Before you purchase your swing check valve, make sure that you know the size and style you need. Measure the pipes you will be attaching the valve to, and check the material. There are threaded valves, socket valves, and materials such as carbon steel, stainless steel, and PVC.
Why is my swing valve leaking?
If you find the cover of your swing check valve leaking, it is most likely caused by loose bolts or a damaged gasket. You can start by simply tightening the bolts and checking if that solves the problem. If not, you will need to replace the gasket on your valve.
What happens if a valve leaks water?
If your valve leaks water when it’s closed, there is likely some sort of damage inside your valve. You should clean your flap and check for damage. You can replace your flap if you find damage, but if there is damage to the body of your valve, you will have to replace the whole thing.
Why won't my water valve open?
If your valve doesn’t open, it’s probably due to some kind of obstruction. You should uninstall your valve and take it apart to find it. Cleaning your valve should allow water to pass through.
Can you install a swing check valve in any direction?
Even though swing check valves can be installed in any direction, you need to make sure they are placed on horizontal and vertical pipelines appropriately.
Why is it illegal to mount a control valve horizontally?
Prohibition against mounting with the stem horizontal was because of bending loads on the bonnet by the cantilevered mass of the actuator. Side-load on the guides from the weight of the valve trim is trivial compared to the fluid forces on the trim.
Why do cryogenic valves have to be vertical?
Cryogenic valves are probably fussiest about being installed with the stem vertical because it is necessary for a long gas bubble to inhabit the extended bonnet. Tip the valve sideways and cryo fluid flows all the way to the packing, making a big iceball, making the valve impossible to move, and chilling the packing so it is too stiff to seal. Worcester recently came out with a packing option that tolerates non-vertical shaft orientation for cryo valves.
What valves work better on a stem?
As pointed out earlier, rotary valves such as butterfly valves, eccentric rotary plug valves, and even ball valves work as well or better with the stem horizontal. One big advantage is that it keeps the outboard bearing from filling with sediment (grit) as it would on the bottom.
What is a 2" or 3" valve?
Another thing i forgot to mention, they are 2" or 3" manual valves and are used either to balance or to divert flow. It seems that after all your experiences opinion the main issue is the fact that they will not be touched on a regular basis and this can cause them to bind.
Can a manual globe valve be adjusted?
Manual globe valves that are placed in position and only adjusted 2 or 3 times in their lifetime will never see any effect from horizontal installation. The cantilevered mass of a simple handwheel is trivial, and supported by the OS&Y (anticipated) construction. It may actually benefit the service life for a valve on a heated service (steam) because the packing will be in cooler air than it would have been with the stem vertical and the convection cooking the valve topworks.
Can a valve be stuck in one position for a long time?
On the other hand: a valve (regulating or other) stuck in one position over a long time might well (under circumstances, but again depending of the valve detailed construction and operating fluid data) give more irregularities (leakage over stem sealings for instance) than a valve regularily operated.
Is a flinana valve horizontal or vertical?
flinana: Since the valve you refer to is manually operated and is used in more of a throttling application than a true control application, it won't make a big difference whether it is installed shaft horizontal or shaft vertical. It is, however, a good idea to check with the manufacturer as others have mentioned.
Where are check valves placed?
Check valves are used in many different applications. For example they are often placed on the outlet side of a pump, to protect the pump from backflow. Centrifugal pumps, the most c
What happens if a check valve is not installed?
If the flow turns and no check valve is installed, water hammer can occur . Water hammer often occur with an extreme force and will easily damage a pipeline or components. Check valves are used in many different applications.
Why are check valves placed on the outlet side of a water pump?
For example they are often placed on the outlet side of a pump, to protect the pump from backflow. Centrifugal pumps, the most common type of water pumps, are not self-priming, and therefore check valves are essential for keeping water in the pipes.
What is the best configuration for a flap type check valve?
Typically the best configuration for a flap-type check valve is horizontally, that is a good default. The vertical pattern check valves definitely can be.
Why do we need a check valve?
Check valves are generally installed in pipelines to prevent backflow. A check valve is basically a one-way valve, in which the flow can run freely one way, but if the flow turns the valve will close to protect the piping, other valves, pumps etc.
What is the difference between a relief valve and a chec valve?
Excessive pressure build up an cause problems such as as shuddering and chattering. Relief valves prevent excessive pressure while chec valves control direction.Hy draulic fuses detect hose or tubing ruptures and shut off excessive flow. Pressure regulation valves use a calibrated spring to bypass pressure to the inlet side of the pump.
