SR5016 zone valve/zone control valve
Product description:
SR5016 series three-wire switching electric valve consist of valve body and replaceable spool, used for controlling the pipes open or close in cold or hot water air conditioning system, to control room temperature. And be designed for a variety of purposes.
Depending on the selected model, you can use single-pole low-voltage controller, the controller can also be used single-pole line voltage to control the operation of the valve. Three-wire type valve will cost small power only when it needs to be open the valve , valve motor power is small, drivers can be free removal, through the valve close and open, so room temperature is always maintained at the thermostat setting temperature range.
Features:
Forged brass body
Stainless steel base, aluminum casing
Fully enclosed hysteresis synchronous motor, stainless steel spring
Body Connection thread: British standard flat thread (female thread) BSPP
North America used pipe thread (female thread) NPT
Motor power, low noise, light weight, easy to use, at the rated voltage frequency of the motor speed is not affected,
Remains constant, if the motor overload or stall, the motor coil will not burn
actuator and valve itself are installed by slip-on connection, which can be quickly and easily disassembled without any tools, so it’s easy to install and use
