Motor driven two-way valve magnetic valves
summary
This electric valves are exclusively central air conditioning fan coil products by drive and body, two parts by a synchronous motors, drives, spring reset drive and manual control valve lever open. Body part adopts piston structure. Motorized valve can be used with temperature, the temperature control valves, electric valves motor open or close, cold and hot water piping of, or by fan coil air temperature, in order to realize the automatic adjustment.
Application scope and product features:
1 for cold and hot water control air conditioning system, piping open or close to control the temperature
2 drive from single hysteresis synchronous motor drive, the valve, the valve spring reset when not working in closed form, when need to work, the thermostat opens signals to provide a motorized valve on the ac power and action
3.. Open valve, frozen water or hot water into the fan-coil unit, provide for the room temperature, air conditioning and heating thermostat setting when to make electric valves, thermostat, reposition spring valve closes, thus truncation into the fan-coil unit, water valve closed and opened by temperature, temperature remains in the set temperature range.
4.. ZYFT series of electric valves and valve actuator adopts screw thread connection, but when valves are installed, then install drives. Field assembly, flexible, convenient connection. Drive to the graphic design can be installed, take up the space is little metope, reliable and durable products, low noise, can be in concealment type fan coil unit commonly wet high temperature environment.
