Electric 3 Way Zone Valve , Heating Motorised Valve Energy Saving Type

Electric Three-way Valve Motorized Valve Energy saving type

SKD Series Electric Two-Way Valve is applied to on-off control for HVAC water system, is composed of driver and valve body. The valve body is casted with excellent brass and the driver is made of flame-retardant engineering plastic, with limit switch inside and manual valve opening mechanism, is easy to debug and test pressure. In which, B type driver has built-in relay, could realize one-line control and multi-valve parallel, match with various temperature control switches.

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℃
◆ Applicable environment temperature:0-65℃
◆ 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.
◆ The medium of two-way valve flows from B to A; three-way electric valve medium flows from AB to A or B.
◆ Do not apply force on the driver while installing, or it may damage the driver; do not apply force on spring stem that protrude the valve deck when disassemble the valve, or it may result in valve stem distortion and leakage. Do not wrap the driver in the thermal layer.

  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.
