Apl Standard Replaceable Valve Seat Triple Offset Metal to Metal Hard Seal Seat Butterfly Valve for High Pressure Media

Apl Standard Replaceable Valve Seat Triple Offset Metal to Metal Hard Seal Seat Butterfly Valve for High Pressure Media. Frictionless Operation: Triple offset design ensures disc disengages from seat instantly upon opening, minimizing seal wear. Bidirectional Zero Leakage: Metal sealing achieves bubble-tight shut-off in both directions per 598. Extreme Temperature Range: Operates from -196 degree C cryogenic to 550degree C high temperature, covering diverse thermal conditions. Compact & Lightweight: Short face-to-face dimension and light weight save installation space compared to gate valves. Long Seal Life: Laminated stainless steel + graphite seat offers excellent wear and corrosion resistance. Fire-Safe Design: All-metal construction with no soft parts, compliant with 607 fire-safe standard. Low Operating Torque: Triple offset geometry significantly reduces opening/closing torque for easy actuation. Field Maintainable: Seal ring can be replaced on-site without removing the entire valve, lowering maintenance cost. ISO 5211 Compliant: Standardized top flange enables quick mounting of various actuators for easy automation. Severe Service Ready: Suited for high temperature, high pressure, corrosive/abrasive media, and LNG cryogenic services across industries.
