Fisher™ 3620JP
The Fisher™ 3620JP Pneumatic Rotary Actuator by Emerson delivers high-torque, precise control for rotary valves in demanding industrial environments. Its double-acting design ensures smooth performance, while the spring-return feature provides fail-safe operation. Compatible with FIELDVUE™ controllers, it enhances reliability, diagnostics, and process efficiency.
The Fisher™ 3620JP Pneumatic Rotary Actuator, engineered by Emerson, is a robust, high-performance pneumatic actuator designed to provide precise, efficient, and reliable control of rotary valves such as butterfly, ball, and eccentric plug valves. Combining high torque output with accurate valve positioning, the 3620JP actuator is ideal for demanding industrial automation and control applications in refining, chemical, oil and gas, power, and general process industries. This double-acting piston actuator converts pneumatic pressure into rotary motion, delivering smooth, high-torque performance and quick response even under variable operating conditions. The Fisher 3620JP features an integral, adjustable spring-return mechanism, ensuring safe fail-open or fail-close operation during power or air supply loss. Its rugged, compact design and corrosion-resistant materials make it suitable for both indoor and outdoor installations. When combined with Fisher FIELDVUE™ digital valve controllers, the 3620JP actuator offers advanced diagnostics, remote performance monitoring, and precise control loop performance, improving reliability and reducing unplanned downtime.

Feature of Fisher™ 3620JP
- The positioner provides accurate, fast response and can withstand the vibrations of most plant environments. Low steady-state air consumption contributes to efficient operation.
- Most of the parts for 3620JP positioners are interchangeable, requiring fewer spare parts to support these positioners.
- With the cover removed, zero span and cross-over adjustments are easily accessible and can be made with a screw driver.
- Easily adjustable minor loop gain fine tunes the positioner to optimize dynamic response for each specific actuator size and application.
- Changes in supply pressure have minimal effect on positioner operation.
- Case, components, and gasket materials withstand harsh environments. Positioner bleed air purges internal parts and actuator housing for additional protection.
- Simple adjustments permit switching between direct and reverse action; no additional parts are required.
