What type of shower stem do I have?
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.
How do you remove a bathroom faucet stem?
Wiggle the handle and pull it off. You may need a faucet handle puller if the handle will not come off by hand. Place a socket wrench over the bathtub faucet stem until it covers the hex nut. Turn the wrench counterclockwise to loosen the nut until you can pull the stem free.
What is a 3 port mid position return valve?
Three port mid position valve The Honeywell V4073A three port, mid position, spring return valve, is a masterpiece of clever engineering. It manages to move to one of three positions using only a cheap non-reversible AC motor, a spring, a couple of micro-switches, a resistor and a diode, and act as a relay for the boiler into the bargain!
How does a mid position 3 port radiator valve work?
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 is the position of the switches on a valve?
This is the circuit diagram of the innards of the valve: The switches SW1 and SW2 are shown in the valve rest position (port B open). As the valve moves over towards the A position, SW1 changes over just before the A+B point, and SW2 just after.
How many micro-switches are used to define the position of the valve?
Two micro-switches, operating just either side of the ‘A+B’ point, are used to define this position. This is the circuit diagram of the innards of the valve:
