SR5121 motorized 2 way 3 way auto electric operated ball valve
Product description:
SR5121 motorized two-way valve consists of the SR 5121-A valve actuator and the SR 5121-B brass valve, 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.
SR5121 motorized two-way valve’s actuator and valve itself use thread connection, the actuator can be installed after the valve is installed. Site assembly, easy wiring. Graphic design of the actuator is suitable for closing the wall, and small occupied space. The Product is reliability and durability, low noise.which can be installed inside the concealed fan coil unit and reliable work in the often high-temperature environment.
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
