Semi-Automatic Peumatic Actuator with Clutch Manual Wheel Operated Metal to Metal Seat Butterfly Valve

Semi-Automatic Peumatic Actuator with Clutch Manual Wheel Operated Metal to Metal Seat Butterfly Valve. Frictionless operation - Triple offset ensures instant seat disengagement, zero friction, greatly extending valve lifespan. Bidirectional zero leakage - Metal hard seal delivers tight shutoff in both directions, meeting ISO 5208 Rate A. High temp/pressure resistance - All-metal sealing pair handles up to 600C and high-pressure applications reliably. Pneumatic quick response - Actuator enables cycle times in seconds, ideal for emergency shut-off and frequent control. Automatic sealing compensation - Resilient seat structure automatically compensates sealing force after wear, maintaining tight shutoff over time. Wear & corrosion resistant - Hardfacing or ceramic coating withstands abrasive particles and aggressive media. Fire-safe design - Metal-to-metal sealing retains integrity post-fire, complying with APl 607 standard. Extended service life - Friction-free and wear-resistant materials support hundreds of thousands of cycles with minimal maintenance. Broad media compatibility - Suitable for water, steam, oil, gas, and mild acids/alkalis across oil, chemical, and power industries. Wafer-type design offers ultra-compact structure and light weight, directly clamped between flanges without bolting, saving space & simplifying installation.
