  • Volume Booster Function: Amplifies a pilot/control pressure signal into a higher-flow pneumatic output to improve actuator response
  • Moderate Flow Capacity: Designed for small to medium actuators requiring fast, accurate actuation
  • Working Pressure: Supports inlet pressures up to ~10–20 bar (model dependent)
  • Bifold (Balanced) Design: Ensures smooth pressure tracking and stable control with reduced hunting
  • Captive Exhaust Vent: Integrated exhaust eliminates the need for external vent piping
  • Independent Fill and Vent Control: Enables rapid pressurization and safe, controlled exhaust
  • Compact Port Sizes: Typically 1/4″ connections for moderate flow with a small footprint
  • Seal Material Options: Multiple elastomer choices (e.g., NBR, Viton) for temperature and media compatibility
  • Media Compatibility: Compressed air and compatible inert gases
  • Typical Use Cases: Pilot pressure boosting for small/medium actuators, control valves, and positioners
  • Robust Industrial Design: Built for frequent cycling and long service life in industrial environments
