What is a 3 port motorised valve?
This type of three way motorised valve has port A normally closed with no power to the valve. In this state, water can flow from port AB to port B. When the electrical supply is activated, the actuator motor overcomes the force of the internal spring and closes port B. This allows water to flow from port AB to port A.
What is a 3 port mid position valve?
Overview. A mid-position motorised zone valve supplied with 22mm compression fittings. It is to be used for the flow control of central heating or hot water in ‘Y plan’ central heating systems. The valve operates in conjunction with inputs from a room thermostat or a cylinder thermostat.
What is the orange wire on a 3 port valve?
Orange, Live Out – this is used to switch the boiler on when the valve is at position A.
- No power.
- Power on White only.
- Power on White and Grey.
- Heating only does not work.
- Radiators never heat up, regardless of other settings.
- Radiators and hot water always work together.
What is the GREY on a 3 port valve?
Valve wiring configuration is: White = Heating on. Blue = Neutral. Grey = Hot water off.
Is a 3 port valve the same as a mid position valve?
Both valves are 3 port. But one is simply a diverter. The mid position valve however flows water to both systems simultaneously when CH is turned on. The hot water will usually be satisfied first due to lower flow resistance which then allows the valve to divert fully to the central heating.
What is the difference between a 2 port and 3 port valve?
A 2-way valve is any type of valve with two ports: an inlet and an outlet port, typically labelled A and AB respectively. With two ports, the valve passes the water in one direction only. 3-way valves have three ports, labelled A, B, and AB. With three ports, the 3-way valve passes the water in two directions.
What does Wmh mean on a mid position actuator?
W=supply hot water to taps. H=supply hot water to heating (radiators).
What does the white wire do on a 3 port valve?
3 Port Valve Operation Electrically, the valve has 5 wires: Green/Yellow, Earth – connected to the metal body of the valve. Blue, Neutral – internally connected to the neutral side of the motor. White, Live in 1 – Activates the motor inside the valve to select either AB (both) or A (heating)
What is a 3 Port compression motorised valve?
3 port compression motorised valves with detachable actuator and detachable cable. These motorised valves are the perfect solution for zoning your hot water or central heating circuits.

What are the different types of motorised valves?
There are two types of motorised valve used in domestic heating systems: two port (also called zone valves), and three port (also called mid position valves). Salus Controls offers both types of valve in a range of standard port sizes. FEATURES
How does a three way motorised water valve work?
Three way valves This type of three way motorised valve has port A normally closed with no power to the valve. In this state, water can flow from port AB to port B. When the electrical supply is activated, the actuator motor overcomes the force of the internal spring and closes port B.
How does a 6sbmv32 three way motorised valve work?
6SBMV32 INSTRUCTION MANUAL OPERATION Three way valves This type of three way motorised valve has port A normally closed with no power to the valve. In this state, water can flow from port AB to port B. When the electrical supply is activated, the actuator motor overcomes the force of the internal spring and closes port B.
