1. Product Title

Fisher 38B5786X132‑ Single‑Acting Relay Assembly for DVC6200 Valve Positioner

2. Product Overview

38B5786X132 is core relay sub‑assembly for Emerson Fisher DVC6200 series digital valve positioner. It converts electrical control signals into pneumatic output pressure to drive single‑acting control valves. This component executes air‑gain and air‑vent logic for valve stroke positioning. Worn relay assembly causes position drift, hunting and slow valve response. 38B5786X132 is a field‑replaceable spare part, restoring positioner performance without replacing the complete DVC6200 unit during plant maintenance and turnaround.
