SR207 DN15-25 BSP 1/2'' 3/4'' 1'' mini electric motor forged brass ball valve

Product introduction:

SR207 electric valve is mainly used in central air-conditioning hot/cold water system, heating system, according to actual needs, to precisely control flow of cold, heat medium, the valve will avoid dramatic changes in temperature, to achieve purpose of real-time precise controlling temperature. The control valve is driven by single phase motor. Motor and thermostat connect by common terminal, starting terminal , closing terminal. Thermostat keeps constantly sampling, processing field data, sending control signals, to make the electric valve motor run or stop, when thermostat works, a opening signal is provided to electric valve which will act by AC power and open the valve, then frozen water or hot water will come into the fan coil to provide the room with cool air or hot air; Once the temperature reaches setting point, the thermostat will make he electric valve power-off then the reset spring makes the valve closed, thus cutting off the flow of water into the fan coil . Through the valve closed or open, room temperature is always maintained at the thermostat setting temperature range.

Features: straight-through flow, large flow, not blocking residue, KVS value is greater than the general two-way valve drive fully enclosed structure, has a good waterproof anti-dust function, valves hot / cold and environmental cold / heat transfer in less than actuators, actuator demolition, equipment is simple, can be installed in equipment, piping after installation, but also help improve the installation efficiency, since the actuator eccentric structure, the valve can be closed against the wall mounting pressure large, close strict, flexible valve open, can effectively prevent water hammer, the actuator can be equipped with two directions, after wiring and maintenance easier, automatic power-off valve operation in place click, click and longer life.
