MOTORIZED 3-WAY ZONE VALVES
VMR valves are motorized valves used in home applications and small installations to control the flow of hot and cold water. They can be used as shunt or mixing valves in centralized heating or cooling systems. The valve, thanks to its cylindrical shut-off, shunts flow which is independent from the differential pressures between the various ports.
This shut-off can have two operating positions depending on how the electric motor that moves it is powered. The head of the valve can be removed without draining the plumbing system: this makes valve maintenance quick and flexible. An auxiliary microswitch can be installed on request and be activated when the valve is switched.
Valves have an external lever for manually positioning the shut-off in its central position, (see relative paragraph).
