Fast Delivery Fi-sher SS-263 Volume Booster Digital Control Valve Positioner Fi-sher Fieldvue DVC6200 Supplier
Fi-sher DVC6200 Digital Valve Controller with Fi-sher SS-263 Volume Booster Package
This product combination pairs the Fi-sher FIELDVUE DVC6200 digital valve controller with the Fi-sher SS-263 volume booster (flow amplifier). Together they form a high-performance solution commonly used in Optimized Digital Valve (ODV) packages to deliver precise digital control and significantly faster actuator stroking on larger pneumatic actuators.
Product Overview
The DVC6200 is a HART-communicating, microprocessor-based current-to-pneumatic instrument that converts a 4-20 mA control signal into a pneumatic output. It features linkage-less non-contact position feedback, automatic calibration, and advanced diagnostics. The SS-263 volume booster amplifies the pneumatic output from the DVC6200, providing high-volume air flow for rapid response to large signal changes while maintaining stable, low-volume output for fine throttling control. The booster has a fixed 1:1 input-to-output ratio, integral bypass restriction for tuning, soft-seat construction, and dual-ported design that boosts both supply and exhaust capacity. This package is particularly effective for large double-acting piston actuators where standard positioner output alone cannot achieve the required stroking speed.

Application Industry
Used in process industries requiring fast and accurate control of large pneumatic actuators, including oil and gas, chemical processing, power generation, refining, and other applications involving large control valves or optimized digital valve packages.
Common Problems
Large actuators often suffer from slow stroking when driven only by a standard positioner due to limited air capacity. Fine control can also become unstable if boosters are oversized. The DVC6200 + SS-263 combination addresses both issues by providing digital precision with tunable high-capacity boosting that responds appropriately to both large and small signal changes.
Replacement Models
This package can replace configurations using older positioners paired with multiple 2625-style boosters. A single SS-263 can typically replace up to three lower-capacity boosters while improving response and reducing tubing complexity.
