Fisher 480 Series Yokeless Piston Actuators

Actuator is a mechanical device used to control valves, dampers, etc. Fisher 480 Series Yokeless Piston Actuators are usually operated by air pressure, but some may operate autonomously by process fluids. Fisher 480 Series Yokeless Piston Actuators are trestle-less piston actuators for throttling and switching applications with ball, butterfly, louvers, dampers, and rheostats. Such actuators require pneumatic pressure from the double-acting positioner (series 3570) or from the switch loading and unloading equipment.

Fisher 480 Series Yokeless Piston Actuators have following features:
Multi-function Actuators – Fisher 480 Series Yokeless Piston Actuators available with or without locators and shock absorbers are available in a variety of sizes, stroke speeds, thrust and stroke to meet most control requirements.
Compact design — a scaffolder-free structure that is tightly connected to the control device enables flat components;Such actuators may be mounted with a stand or, for some versions, directly to the bonnet flange.
Extensive air source pressure features — The cylinder (and 3570 locator (if used) can use air source pressure as low as 2.4 bar (35 psig) or as high as 10.3 bar (150 psig).
Long stroke — The maximum rated stroke of the actuator is up to 206 mm (8.125 in.).
Multi-function locator – the locator/actuator can be operated reversible on site without other parts.The positioner sensitivity, stroke range and stroke starting point have been set in the factory. Reset only when the working conditions change or the positioner is operated in reverse.
