High Pressure parallel slide gate valve normally applied in the power station for the high temperature and high pressure medium service, more often the pressure seal bonnet design, and high pressure ranging from 600lbs ~2500lbs.
Features: 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. The internal travel position stops and position indicator available.
Main Materials: carbon steel, low alloy steel, austenitic stainless steel, nickel alloys,
Stainless Steel Titanium, Inconel, Monel, Super Duplex, etc.
