Designed specifically for extreme high-pressure and high-temperature services, this heavy-duty 3-Inch WCB Cast Carbon Steel Gate Valve features a highly reliable Pressure Seal Bonnet (PSB). Unlike traditional bolted bonnets, the pressure seal mechanism utilizes the line pressure to create a tighter seal—the higher the internal pressure, the tighter the seal. Equipped with a robust bevel gear operator for effortless control, it is the ultimate shut-off solution for power plants, offshore platforms, and severe-service oil refineries.
