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.
