Product Overview
The FISHER DVC6200 is a high-performance digital valve controller (valve positioner) engineered by Fisher (Emerson) for precise, closed-loop control of pneumatically actuated control valves. Unlike a hydraulic pump, the DVC6200 is a process control instrument that receives a command signal from a host control system and modulates the valve actuator to achieve the desired valve stem position. It utilizes a two-stage, high-capacity pneumatic relay and a contactless magnetic position feedback system to deliver accurate, repeatable valve positioning. The DVC6200 is a LINKAGE-LESS design, eliminating mechanical wear components and reducing maintenance requirements. It is a core component in process automation loops across the oil and gas, chemical, petrochemical, power generation, and refining industries, providing reliable performance in demanding industrial environments.
