How does a Drayton 3-port valve work?
How does a Drayton 3-port valve work?
Drayton diverter valves are spring return valves which allow water to be directed out of either one of two outlets. When the drive motor is de-energised the flow is from inlet Port C and out of Port B. When the motor is energised, flow is out of Port A.
What is a mid position 3-port valve?
How the Mid-Position Three Port Valve works. The spring pulls the valve to open the flow through port B (traditionally connected to the hot water cylinder’s heating coil), while the motor winds it towards opening port A (feeding the radiator circuit).
What’s the difference between a 3-port valve and a mid position valve?
The motorized midposition diverter valve has a three position operation, meaning that the valve can move into 3 different positions: hot water only, heating only or mid position supplying both hot water and heating together. The mid position valve actuator has 5 wires, the diverter valve actuator has 3 wires.
What position should 3-port valve be in?
mid position
The valve should go to the mid position with both Port “A” and Port “B” open. The boiler should fire and the pump should run. The pipes connected to Port “A” and Port “B” should get hot. Once satisfied with the valve operation, reset the programmer and the thermostats to normal control settings.
How do you free a stuck diverter valve?
After you remove the lid of the boiler, you have to locate the diverter valve mechanism. Run tap water on hot and observe the diverter valve. If you run hot water, the valve is supposed to close in order to divert it to the tap, meaning it should move. If you see no movement, then it’s stuck.
Why is my diverter valve stuck?
Diverter valves can become damaged or stuck. This is because they’re a moving part and can be oscillating between being open or closed many times a day. However, they are fixable. If you have no hot water, try turning the heating on.
