Pressure Seal Gate Valves
High-pressure sealing gate valves for severe service

Pressure Seal Gate Valves
Overview
Pressure seal gate valves are engineered for high-pressure, high-temperature isolation. The self-energising pressure-seal bonnet tightens further as internal pressure rises, giving a dependable, leak-tight joint suited to power, refinery and boiler service.
Key Features
- Self-energising pressure-seal bonnet
- Sealing tightens as pressure rises
- Full-bore, bidirectional isolation
- Renewable seat rings
- Butt-weld and flanged ends
Applications
Power plants Boiler feed Refineries High-pressure steam Petrochemical
