The pneumatic actuator-operated butterfly valve integrates a high-performance centerline/double eccentric butterfly valve with a rack and pinion or fork-type pneumatic actuator, achieving rapid opening and closing and precise adjustment from 0-90° using clean compressed air. The valve body features a streamlined disc-shaped flow channel, resulting in extremely low pressure drop when fully open and a zero-bubble seal when closed. Specifically designed for automated processes, it meets the stringent requirements of modern industry for speed, safety, and energy efficiency.
Product Advantages:
Rapid Opening and Closing
Single-acting ≤0.5 s, Double-acting ≤1 s, reducing water hammer and media waste.
High Torque Output
The fork structure provides up to 15,000 N·m, easily driving DN1200 large-diameter valve plates.
Long-Lasting Sealing
EPDM/PTFE composite rubber lining maintains ANSI Class VI zero leakage even after 500,000 cycles.
Fireproof and Anti-static
Compliant with API 607 & ISO 10497, suitable for flammable gas and dusty environments.
Modular Connection
Actuator and valve body use ISO 5211 standard flanges; on-site replacement of electric/hydraulic actuators takes only 10 minutes.
Significant Energy Saving
Air-driven power consumption is only 1/3 of that of electric actuators of the same specifications; spring reset is available in case of air source failure, ensuring a safe position.
