Knowledge about Pneumatic Actuator

The GW Fork Type Pneumatic Actuator is a heavy-duty, high-performance actuator designed for automating quarter-turn valves (such as ball valves, butterfly valves, and plug valves). It features a fork-type coupling mechanism that ensures precise 90° or 180° rotation with strong torque transmission, making it ideal for industrial valve control applications.
Key Features:
✔ High Torque Output – Provides excellent rotational force for smooth and reliable valve operation.
✔ Robust Construction – Made of high-grade aluminum alloy or stainless steel for durability and corrosion resistance.
✔ Compact & Lightweight – Space-saving design suitable for confined installations.
✔ Double-Acting / Spring-Return Models – Choose between air-to-air operation or fail-safe (auto-close/open) functionality.
✔ ISO 5211 Mounting Standard – Ensures easy and secure attachment to compatible valves.
✔ Long Service Life – Low-friction design reduces wear and maintenance needs.
Common Applications:
Oil & Gas – Pipeline isolation and control
Chemical Processing – Handling corrosive fluids
Water Treatment – Flow regulation in pumps and dosing systems
Power Generation – Steam and cooling system valves
Marine & Shipbuilding – Seawater-resistant valve automation
The GW Fork Type Pneumatic Actuator is a cost-effective, reliable, and low-maintenance solution for industries requiring fast, precise, and durable valve automation.

What Our Customers Say About Us

We’ve been using COVNA pneumatic valves in our automated production line for over a year, and their performance has been flawless. The fast consistent sealing under high-cycle conditions have significantly reduced downtime. Even with continuous 24/7 operation, the valves show no signs of wear. Highly recommended for industrial applications!"

After switching to these COVNA valves in our chemical processing plant, corrosion and leakage issues dropped to zero. The stainless-steel body and high-grade seals withstand aggressive media, while the responsive actuation improves process accuracy. Service life is impressive—no replacements needed after 18 months! I will still choose covna in the future!Best Regards,Leandro Estrada
