API PRESSURE SEAL GLOBE VALVE
API Pressure seal gate valves are used for high pressure service, typically for pressures above 100 bar. The unique feature of the pressure seal bonnet is that the body-bonnet joints seal improves as the internal pressure within the valve increases
Specifications
1.Valves in intermediate classes reduce total cost of ownership
2.Pressure-Seal mechanism utilizes line pressure to enhance seal; ensures sealing integrity at higher operating pressures.
3.In-situ hardfaced seat design for all sizes
4.Higher hardfacing thickness (3 mm) to ensure consistent hot hardness
5.Body-guided Disc offered in Pressure-seal Globe Valves (all sizes/classes) provides disc stability and avoids vibration of the disc-disc nut assembly
6.Disc guides hardfaced for longer life
