Hydraulic Central Air Conditioner Fan Coil / Electric Motor Valve
The SK series brass motorised valves are primarily designed to control the flow of water or steam in response to the demand of a controller in zone and fan coil applications.
The valve is driven by hysteresis synchronous motor with spring return. The valve is normal-closed. When thethermostat is working, it will provide an opening signal, and the motorized valve will be turned on to open. Thenthe chilled/hot water will enter into the coil and supply the cold/hot to the room. When the room temperature risesup to the set point, the thermostat will make the valve power off. At the same time the valve will be closed byreturn spring and the water to the coil will be shut off. The room temperature will be kept in the setting range allthe time through the opening and closing of the valve.
Technic parameters
| Power supply | 220~240VAC 50/60Hz |
| Full stroke time 'on' | approx.10s |
| Full stroke time 'off | approx.5s |
| Close-off pressure | 0.2Mpa |
| Application | Chilled/Hot water |
Features
1.Inlay contact switch, the motor is power off after the valve completes open and close, so it has long service life and power saving, but is also safe.
2.The valve body is separated with driver, could be disassembled rapidly.
3.The valve body structure is unique, is allowed of big pressure difference.
4.The driver has manual controller is available for system debugging and maintenance, the manual opening is about 70% (push down the white driving arm to the bottom, and then push inside, when the power is recovered, the valve and driver will return to automatic position)
5.B type driver has inlay relay, one-line control and three-speed switch, realize multi valves parallel, and match with various temperature control switches. (special for four-pipe)
6.Select ordinary driver, one temperature controller matches only one electric vale, or any results caused will be nothing with manufacturer.
Pipe Connecting Instruction
Motorized control valve should be mounted on cold/hotwater inlet or outlet pipe of fan coil unit for opening orclosing cold /hot water. The actuator is controlled by theroom thermostat.
2-way valve(see Fig 1) is installed on cold/hot return water (CHR) pipe , when de-energized, the rubber insidenormally closed at port "B" , stop water flow. when energized, the rubber moved from port "B" to the centerof port "B" & "A" and cold/hot water flow through 2-wayvalve to return water pipe.
When the actuator is de-energized, spring returnmechanism drives valve to normally closed position,port "B" is closed . Cold/hot water inlet from port "AB"(bottom)by-pass to port "A" to return water pipe ,
when energized , rubber is moved from port "B" to port"A" and closed. Cold/hot water inlet from port "AB"through port "B" to fan coil unit then outlet to returnwater pipe.
Caution:
2-way valve should not be installed in wrong flow direction to avoid vibration and noise; By-pass valveand Exp Tank is needed for water flow fluently.
