Pressure Seal Bonnet Gate Valve

Pressure Seal Gate Valve

Pressure seal construction is for high temperature high pressure service, tycially pressure is 900LB, 1500LB, 2500LB, 3000lb, 4500LB. Compared to other constructions, Pressure seal is body-bonnet joint seals, he sealing is achieved by the internal pressure that pushes the bonnet against the gasket providing the sealing.
