Fan Coil Unit Hysteresis Synchronous Motor With 1.6MPa Low Pressure BSPP Connection

1.6MPa Fan Coil Unit Water Brass Motorised Zone Valve

SK series brass motorised valves are primarily designed to control the flow of water or steam in response tothe 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.

Technical data
◆ Driving voltage:220VAC 50Hz/60Hz (12V,24V,110V are available for choice)
◆ Power consumption:5VA (Only in the course of open and close)
◆ Pressure-bearing of valve body:1.6MPa
◆ Allowance pressure:0.6MPa
◆ Applicable medium:cool water and hot water
◆ Open and close time:about 16 s for open,about 16 s for close
◆ Temperature of applicable medium:1-95℃
◆ Connection manner:ZG internal pipe thread (could be custom made)

Character of structure
◆ 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.
◆ The valve body is separated with driver, could be disassembled rapidly.
◆ The valve body structure is unique, is allowed of big pressure difference.
◆ 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)
◆ 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)
◆ Select ordinary driver, one temperature controller matches only one electric vale, or any results caused will be nothing with manufacturer.
Points for installation:
◆ Please read this instruction carefully before installation, ask professional to perform installation and connect according to wiring diagram.
◆ 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.
◆ Clear up the sundries in the pipe before installation, install 50 mu (or thinner) filter in the front end of electric valve.

  We started producing electric in-floor heating in Jiangsu,China almost eight years ago in 2011 and have been growing steadily ever since. In 2015 we started selling our own specially-designed lines of in-floor heating products and two years later once we were confident had a winning product line we started offering them on-line to customers like you all across North Europe. During the summer of last year our sales had grown so much that we moved distribution and fulfillment from Lishui Distrct,Jiangsu to Jiangning Distrct, Jiangsu where we now have more space and offer quicker freight to many parts of the country more easily and at a lower cost than before.

  I invite you to check out our competitive pricing and to send us a request or call me personally if there is anything we can do to help you get started.
