Parallel Slide Gate Valve can also be bolted bonnet design. The parallel slide discs are fully open and closed position free of any frictions. The discs are spring load for bi-directional sealing zero leakage. The hard coated sealing surface is highly resistance to the abrasive medium, and slide design allows the self cleaning the surface contact area. The bypass valve can be optional for equalizing the body pressure.
