Fan Coil Electric Actuated Spring Return Actuator Motorized Valve 1.6 MPa Brass Ball Control Valve

Technic parameters:

Character of structure
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.

Points for installation
1.Please read this instruction carefully before installation, ask professional to perform installation and connect according to wiring diagram.
2.The electric valve should be installed to the place with certain distance from around articles, but also could be reached by maintenance person. No electric equipments are allowed to install under the valve body, as to avoid leakage and danger. The driver shall be above the valve body horizontally.
3.Clear up the sundries in the pipe before installation, install 50 mu (or thinner) filter in the front end of electric valve.

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.
