Features that Add Value:

• 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

Versatile Solutions:

• 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
