Motorized Valves

La description

Descriptions: Motor with spring return, provide an opening signal, control the opening or closing for the pipe in the chilled/hot water system MV*2 series motorized valves are used to control the opening or closing for the pipe in the chilled/hot water system so to control the room temperature. The valve is driven by hysteresis synchronous motor with spring return. It is normally close ball valve.When the thermostat is working, it will provide an opening signal, and the motorized valve will be opened. Then the chilled/hot water enters the coil and the coil starts to supply the cold/warm air to the room. When the room temperature rises to the set point, the thermostat will cut the valve power off. At the same time the valve will be closed by return spring and shut off the water to the coil. The room temperature will be kept in the setting range all the time through the opening and closing the valve. MV*2 series motorized valves have three types: normally close *-way normally open *-way and mixing *-way. They have four sizes: 1/2", 3/4", 1” and *1/4". There are also different pipe connection for customers' selection: BSP(G), NPT(N), SWEAT(S), INVERTED FLARE(F), etc. The valves models with KA behind are equipped with auxiliary switches to control other devices and meet different requirements.
