Design features

The swing check valve has a unique non-percussive rubber check valve, which has satisfied the more demanding demands of the site;
This rubber check valve not only has zero leakage, but it can significantly reduce the water hammer and water hammer because the disc is fully covered by NBR rubber and the device has a slope Angle of 40 degrees.

Product range:
The valve valve integral glue, ensure the purity of the medium, long service life.
Low pressure, low pressure seal performance.
Whole watershed design, water head loss is small.
Low voltage opening and closing performance is good.
Can install hydraulic buffer cylinder, increase the slack function.
Body surface spraying powder epoxy resin, good corrosion resistance.
The disc adopts NBR rubber coating, anti-corrosion and good sealing property.
The structure is simple, except for the valve cover, only an elastic disc in the interior.
Full flow design, water head loss small, not easy to accumulate sundries, maintenance
