Product Overview

F5‑MEC‑420 is valve position feedback unit for Flowserve‑PMV pneumatic valve actuators. It converts mechanical valve‑stroke movement into standard 4‑20 mA analog signal for DCS / PLC valve‑position monitoring. Visual mechanical dial provides on‑site local stroke indication. Designed for harsh petrochemical field‑valve environments. Available as refurbished and new‑old‑stock spare parts for control‑valve loop maintenance.

Application Notes

‑ Complete mechanical stroke calibration after mounting on actuator. ‑ Use instrument‑grade shielded cable for 4‑20 mA signal loop. ‑ Follow hazardous‑area installation rules for explosive‑atmosphere sites. ‑ Typical deployment: refineries, chemical‑plant, oil‑gas pipeline control‑valve spare‑part stocking.
