Valve Actuators
Linear: Piston Actuators

Linear: Piston Actuators

Here you can learn about how piston linear valve actuators work, their key advantages, technical specifications, and typical industry uses - and browse our full range of products.

How do linear: piston valve actuators work? 
Piston actuators use compressed air, gas, or hydraulic fluid to drive a piston in a linear motion. This force moves the valve stem directly, making them suitable for high‑thrust applications such as large control valves or severe‑service isolation.
Advantages of linear: piston valve actuators...
• High thrust output
• Handles large valve sizes
• Suitable for high‑pressure service
• Long service life
Technical Parameters:
Pressure Ratings
Dependent on valve design - supports: PN10, PN16, PN25, PN40, PN63, PN100, CL150, CL300, CL600, CL900, CL1500, CL2500
Temperature Range
Typically –20 °C to +80 °C Extended‑temperature models: –40 °C to +120 °C (Valve limits may differ)
Size Range
Suitable for valves DN50–DN2000 (2″–80″)
Materials
Carbon steel, stainless steel, alloy steels, anodised aluminium
