Metal Seated Zero Leakage Ap1 609 Standard Triple Offset High Pressure Turbo Worm Gear Flange Butterfly Valve

Metal Seated Zero Leakage Ap1 609 Standard Triple Offset High Pressure Turbo Worm Gear Flange Butterfly Valve. 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. Severe Service Ready: Suited for high temperature, high pressure, corrosive/abrasive media, and LNG cryogenic services across industries. Worm gear reducer multiplies handwheel torque for effortless operation; built-in self-locking holds any position securely without extra brakes, ideal for medium-large sizes and frequent throttling.
