Globe Valves – Pressure-seal

Valves in intermediate classes reduce total cost of ownership
Pressure-Seal mechanism utilizes line pressure to enhance seal; ensures sealing integrity at higher operating pressures.
In-situ hardfaced seat design for all sizes
Higher hardfacing thickness (3 mm) to ensure consistent hot hardness
Body-guided Disc offered in Pressure-seal Globe Valves (all sizes/classes) provides disc stability and avoids vibration of the disc-disc nut assembly
Disc guides hardfaced for longer life
Customised deposition process in F91/ C12A valves to avoid delamination of hardfaced surfaces
Live loading of bonnet bolts for F91/ C12A valves
Special high purity graphite packing (seven rings) provided for pressure rating > Class 2500 in Power applications

Available in a cast and forged steels and exotic metallurgies for a wide variety of applications
By-pass arrangement provided for over-pressure protection based on customer requirement
ValvTrac™ RFID tagging offered for reliable digital traceability
