How does a sequential shower valve work?
A sequential valve has a single lever that works rather like the knob on your cooker. When the lever is fully anti-clockwise the shower is off. As you rotate the lever it turns the shower turns on. With a sequential valve “on” means fully on so you have full pressure straight away.
What is the difference between a shower head and shower valve?
The showerhead may be where water flows from, but the shower valve controls the water pressure and temperature to ensure an enjoyable shower experience. Your shower valve is what makes the difference between a shower that turns scalding hot after a toilet is flushed and one that maintains its temperature when someone uses another water fixture.
What are the different types of shower faucet valves?
There are a few different types of shower faucet valves to know about. One of the most common valves, pressure balancing valves (PB valves) automatically control the balance of water pressure between hot and cold water.
What is a thermostatic shower valve?
A thermostatic shower valve keeps the water temperature within a +/- 2°C range. So that there is no noticeable temperature change while showering. If the incoming water flow reduces, the valve will compensate and maintain a constant temp. To prevent scalding, thermostatic valves will shut off if either hot or cold water fails.
What does sequential mean in a shower?
A sequential control is one where the on/off operation and temperature control are achieved by turning the same control knob; the first movement turns the shower to the cold position and any subsequent movement counter clockwise increases the temperature up to a set maximum (preset 41°C).
What is a sequential mixer shower?
A sequential mixer shower features just one control lever which changes the temperature with a constant flow. Furthermore, the Kensey sequential is TMV2 approved for its excellent thermostatic temperature control, keeping a consistent, comfortable temperature even when incoming water pressure changes.
What are the different types of shower valves?
In a nutshell, there are three different types of shower valves on the market: pressure balancing shower valve, thermostatic shower valve and diverter shower valve.
How does a sequential thermostatic shower valve work?
A sequential valve has a single lever that works rather like the knob on your cooker. When the lever is fully anti-clockwise the shower is off. As you rotate the lever it turns the shower turns on. With a sequential valve “on” means fully on so you have full pressure straight away.
What is the difference between a mixer shower and a thermostatic shower?
A manual mixer shower will mix hot and cold water to a set temperature but, unlike a thermostatic shower, it cannot react to sudden changes in temperature. A thermostatic shower instantly reacts to a change in water temperature and adjusts the water accordingly to get it back to the pre-set temperature.
What's the difference between a diverter shower and a mixer shower?
Diverter get concealed inside wall where the spout and the lever (knob) are different parts unlike wall mixer. Since all the functional parts get concealed in wall, there's only an aluminum sheet with lever, spout and overhead shower visible.

What is the most popular shower valve?
Pressure balancing valvesPressure balancing valves, also called mechanical or anti-scald valves, are the most common types of shower valves. A pressure balancing valve is designed to rebalance the water pressure to keep the shower from becoming excessively hot.
How do I know which shower valve to buy?
1. Count the Number of Shower Faucet Handles. Often, the type of shower faucet and handle(s) will indicate what kind of shower valve is behind it. Zero handles may imply a shower panel faucet with buttons to control water flow and temperature.
Are thermostatic shower valves worth it?
Thermostatic showers have the advantage of being safer for children and the elderly, who are especially at risk of shower scalds, thanks to their “set it and forget it” property. Even if your water heater is set to a higher maximum, the water temperature will not exceed the maximum that you set on the shower control.
What is the advantage of a thermostatic shower valve?
Thermostatic shower valves allow you to pre-set the water temperature, ensuring that the water won't become hotter or colder than your desired setting while still allowing each person to manually adjust the water temperature.
What is the difference between a mixing valve and a thermostatic mixing valve?
Using a mixing valve can also extend the storage capacity & size of the hot water source. Thermostatic mixing valves react very well to changes in temperature, but they can also handle pressure variations (around 10%). They will maintain stable outlet temperatures given large inlet temperature variations.
What are the different types of shower mixers?
There are three types of shower mixer taps: a double-handle mixer, a mechanical mixer or a thermostatic mixer.
What is a sequential mixer tap?
The mixer tap has a fixed spout with a chrome plated brass body, and chrome plated lever. The sequential lever rotates through 180 degrees increasing temperature from cold to hot, making it ideal for less abled and younger users.

Are mixer showers any good?
Pros of mixer showers: Many homes come with mixers already fitted. Uses a gas boiler rather than electricity to heat the water, which is preferable in some households. Thermostatic mixer showers allow you to regulate temperature. A wide variety of different models offer you a tailored showering experience.
What is a shower panel?
A recent newcomer is the shower panel or shower tower. This is a single unit that contains everything you need for a sensational shower. Specifications vary but usually include a shower valve (often thermostatic), a diverter, a fixed shower head, a hand held shower and several body jets. Shower panels are easy to install but can require quite high water pressure to work well so you may want to install a shower pump as well.
How many controls does a twin valve have?
Unlike a single lever valve, a twin valve has two controls, one control for the rate of water flow and a second control for the water temperature.
What is a manual shower?
This is the most basic type of shower. Most manual showers have a single lever control that you use to control the flow of the water and the temperature. They are very simple to use and usually are not expensive.
What tank does a shower valve feed from?
The shower valve mustbe fed from acold water storage tank and a hot watercylinder. The use of a Surrey or Essexflange connection to the hot watercylinder will ensure an independentsupply of hot water to the valve; thisaction will stop air being drawn into thesystem.
What is the operating pressure of a shower valve?
This shower valve is suitable for use on all common types of plumbing systems including gravity, pumpedand fully modulating combination boilers and high pressure unvented systems.Minimum operating pressure 0.1 bar.
What is the need for a sequence valve and how can it control the pressure?
In order to do certain processes, two or more actuators working in a parallel circuit must move in sequence and it can only be done by using separate directional control valves and limit switches but it won’t be a safe process so for this purpose we can use a sequence valve.
How does a sequence valve operates and what are the parts of sequence valve?
As the name implies the sequence valve can control a sequence of operations, If a preset pressure is reached the sequence valve would allow the flow to branch circuits, instead of sending flow back to the tank. The sequence valve would use a pressure signal to shift the spool and thereby opening or closing a flow path at a preset pressure. So this valve could divert the flow in a predetermined sequence it can operate the cycle of a machine automatically. The sequence valve could be a direct pilot operated or a remote pilot operated type. The construction of this type of valve is similar to the direct relief valve. The sequence valve has two major ports, one of these ports connects the main pressure line and the other one is connected to the secondary circuit. Mostly the secondary port is closed by the spool and the pressure on the spool works against the spring force. So if the pressure exceeds the preset value of the spring the spool lifts and the fluid will flow from the primary port to the secondary port.
What are the advantages of sequence valve?
It can provide a sequenced series of operations such as in a clamp and lift circuit
Why does a sequence valve generate heat?
A sequence valve could generate a great amount of heat because the first actuator to move takes higher pressure than the subsequent actuators. So because of this, there will be a high-pressure drop in the sequence valve and it is wasted energy.
What is a pilot operated sequence valve?
Pilot operated sequence valve. This type of sequence valve has an internal pilot and external drain. The inlet pressure that acts on the pilot seat area causes the ball to move back against the spring and this would create a flow to the tank through the drain port.
How does a sequence valve work?
By using a sequence valve the automatic sequencing of two or more actuators in the hydraulic circuits can be done . The primary actuator would move when the fluid flow is directed to the actuator section of the circuit. The sequence valve would block the flow to the secondary actuator until a predetermined pressure is reached after that it would allow the fluid to flow to that actuator. A sequence valve is fitted with a check valve and this would allow the free flow of the fluid around the valve when the actuator direction is reversed. The sequence valve is used when two circuits are supplied by one pump and one circuit has priority over the other. The sequence valves are used in the hydraulic circuits.
What happens if the pressure of the spool exceeds the preset value of the spring?
So if the pressure exceeds the preset value of the spring the spool lifts and the fluid will flow from the primary port to the secondary port.
