Description de produit
Product Overview

The Fisher 3620J electro-pneumatic positioner delivers accurate, reliable valve positioning for single-acting rotary actuators. It combines the proven 3610J pneumatic positioner with the 3622 electro-pneumatic converter to convert a 4–20 mA DC control signal into proportional pneumatic output pressure. Designed for Fisher 1051, 1052, and 2052 actuators (and compatible with V500 and Vee-Ball™ valves), the 3620J ensures precise stem rotation in demanding process applications.

Key Features
  • Field-reversible direct or reverse action without additional parts
  • Excellent linearity (±1.5% direct / ±0.75% reverse) and low hysteresis (0.75% of output span)
  • Low steady-state air consumption (0.49 normal m³/h at 1.4 bar supply)
  • Simple minor loop gain, crossover, zero, and span adjustments
  • Full hazardous-area approvals (CSA, FM, ATEX, IECEx) and EMC compliance
  • Easy cam change and installation on actuator housing

Applications

Ideal for precise control of rotary valves in oil & gas, chemical, power, and refining processes where accurate positioning and hazardous-area certification are required.

Frequently Asked Questions
Q: Can the 3620J be converted from direct to reverse action?
A: Yes — simply reposition the reversing plate and, if needed, add or remove the counter spring.
Q: Is natural gas approved as supply medium?
A: No — the 3620J is not approved for natural gas supply.
Q: How do I calibrate split-range operation?
A: Use the range spring hole corresponding to the desired 4–20 mA split and follow the zero/span procedure.
