SR201 HVAC AC24V 110V 220V motorized ball valve for FCU control Quality Choice

Product description:

SR201 electric two-way valve is used in controlling the cold or hot water pipe on or off in air conditioning system, for the purpose of controlling room temperature. valve is driven by hysteresis synchronous motor, returned by spring. When the valve does not work, it’s in normally closed state, when it works, A opening signal is provided by thermostat, to make the electric valve connect AC power and become opening state, cold water or hot water flows into the fan coil, to provide cool air or hot air for room; once the room temperature reaches the setting point of thermostat, the thermostat will shut down the power of electric valve and the spring will return to make the valve closed, thus cutting off the flow of water into the fan coil. As the valve closed or open, room temperature is always maintained at the thermostat setting temperature range.

SR201 series has two forms : two-way normally closed valve and three-way split valve, the sizes of valve threads are DN15, DN20, DN25 three type.

SR201 electric valve’s actuator and valve itself are installed by slip-on connection, So, the actuator can be installed after the valve is installed. 

Features:

Forged brass body

Stainless steel seat, 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
