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.Â
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.

Alumina grinding media is mainly used in ceramic,glaze,paint,zirconia silicate,aluminum oxide,quartz,silicaon carbide,talc,lime carbonate,kaolin,titanium and other materials grinding and mechanical equipment accessories.
Advantages
1. high wear-resistance
The Alumina Balls` wear-resistance is higher than the common alumina balls`. When it is working, the ball won`t pollute the grinding materials, so it can keep the purity and improve the stability of grinded materials especially the ceramic glaze.
2. high density
The high density, high hardness and the high grinding characters save the grinding time, enlarge the smashing room. So it can improve the grinding efficiency.
3. Comparing with natural balls and stones, flint pebbles, France pebbles, our balls will help you save more costs: abridge milling and grinding time, improve the utilization of your ball mills, decrease the milling and grinding loss, and save electricity
4. Three kinds of high Alumina Grinding Balls and one kind of alumina lining available.
