Pressure Seal Gate Valve
The Pressure Seal Gate Valve from Hitech Valves is designed for extremely high-pressure and high-temperature applications where absolute sealing integrity is essential. Its pressure seal bonnet design ensures tighter sealing as internal pressure increases, reducing maintenance needs and enhancing long-term performance in severe service environments.
This valve is widely used in power plants, boilers, superheated steam lines, high-pressure process units, refineries, petrochemical systems, and critical isolation applications.
