Linear Stroke Pneumatic Actuator for Valves
A Linear Stroke Pneumatic Actuator is a compact, high-performance device designed to automate valve operation using compressed air. It converts pneumatic energy into precise linear motion, enabling smooth and reliable control of gate valves, globe valves, and other linear-motion valves.
Key Features:
Fast & Precise Movement – Delivers quick, accurate stroke control for efficient valve positioning.
Durable Construction – Made of corrosion-resistant materials (e.g., aluminum, stainless steel) for long service life.
Fail-Safe Options – Spring-return or double-acting configurations for safety in critical applications.
Easy Installation – Compatible with standard valve mounts and pneumatic systems.
Low Maintenance – Minimal wear due to simple, robust design.
Typical Applications:
Oil & Gas – Pipeline shut-off and control
Water Treatment – Flow regulation in pumps and dosing systems
Chemical Processing – Reliable operation in corrosive environments
Power Plants – Steam and coolant valve automation
