PNEUMATIC ACTUATORS
Linear Pneumatic Actuator
tagline
Product Overview
LF-series linear pneumatic actuators deliver straight-line motion for globe valves, control valves and damper drives. Diaphragm versions provide sensitive modulating control; piston versions deliver higher thrust for larger valves. Adjustable stroke, fail-safe spring return and positioner integration make them versatile for process automation.

FAQ
Questions Buyers Ask
What is the difference between diaphragm and piston linear actuators?
Diaphragm actuators are sensitive and ideal for modulating control with low supply pressure. Piston actuators deliver higher thrust for larger valves and heavier loads.
Can you match an actuator to our existing control valve?
Yes. Send us your valve make, model and stroke, and we will size a compatible actuator with the correct mounting kit.
Do you supply positioners and feedback?
Yes — smart positioners with HART or 4-20mA control, limit switches and feedback transmitters are available as integrated packages.
