What is the diverting valve used for?
Diverter valves switch the flow of water between the tub faucet and the showerhead. Water flows directly through the faucet and into the bathtub when the valve is open. When the valve is closed, water pressure forces the water to run upward to the showerhead.
What’s the difference between a mixing valve and diverting valve?
In a mixing valve, two incoming streams are combined into one outgoing stream. In a diverting valve, the opposite takes place. The exiting port of the mixing valve and the entering port on the diverting valve are called the common port, typically labeled C (for common), or sometimes AB.
What is a 3-way diverting valve?
3-way Diverting Valves. Based on desired function, 3-way valves can be installed either as mixing or diverting valves. While a mixing valve has two inlets (A and B) and one outlet (AB), a diverting valve has one inlet (AB) and two outlets (A and B). In diverting valves, the plug closes against the seat.
How does a flow diversion valve work?
Flow diversion valves in an HTST pasteurizer are designed to move to the fully diverted position when the air or power supply is cut to the valves. Flow diversion cheaters include all devices that interfere with these failsafe aspects of the flow diversion valves.
Do I need to turn off the water to change a diverter valve?

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 is the function of Fdv?
The role of the FDV is to prevent unpasteurised milk from progressing to the packaging stage of the process, by returning such milk to the pasteuriser balance tank if the temperature as measured by the thermistor drops below the target (set point) pasteurisation temperature.
What is Fdv valve?
The FDV Valve consists of a valve body with a large opening and integrated seat, a horizontal disc that seals against the valve seat and an actuator installed vertically under the valve body and directly connected to the valve disc by a vertical shaft.
How long does it take to change a diverter valve?
You should call a gas safe registered engineer if you need to replace the diverter valve or service the working parts of the valve after you’ve diagnosed the problem. It shouldn’t take more than an hour for this to be done on a boiler under eight years old, as parts should be readily available.
