Fisher 585C Piston Actuator

The Fisher 585C piston actuator provides low to medium thrust output for a variety of small to medium Fisher sliding-stem valves, including the easy-e™, HP, EH, and 461 valves. Its double-acting design ensures stiff and precise positioning. Smaller sizes are available with optional bias springs for spring return fail modes, making this actuator versatile in various process control applications.

Key Features

• High Thrust Output: Maximum thrusts of up to 111 kN (25,000 lbf) depending on actuator construction.

• Stroke Options: Available strokes of up to 203 mm (8 in) depending on actuator size.

• Universal NAMUR Mounting: Ensures consistent mounting and provides vibration resistance per ISA-S75.13 standards.

• Double-Acting Design: Results in stiff, precise positioning for high control accuracy.

• Handwheel Options: Size 25 and 50 actuators are available with a top-mounted handwheel, while all sizes can accommodate a side-mounted handwheel.

• Optional Bias Springs: Provides spring return fail mode, allowing for reliable operation in case of air supply loss.

• Low Friction: Piston seals and cylinder coatings are designed to reduce friction and wear for enhanced durability and performance.
