Model Number: VBP-12

Request a quote View Prices

Volume Booster Function: Amplifies a pilot/control pressure signal to deliver very high pneumatic flow, improving response speed and effectiveness of large actuators and control valves
Highest Flow Capacity in VBP Series: Designed for large‑demand systems where significant flow amplification is required
Working Pressure: Supports inlet pressures typically up to ~20 bar (model dependent) with robust downstream performance
Captive Exhaust Vent: Built‑in exhaust port eliminates need for external vent piping
Independent Fill and Vent Control: Provides controlled flow into and out of actuators for rapid actuation and safe venting
Large Port Sizes: Usually 1/2″ or larger process connections to accommodate high flow volumes
Seal Material Options: Various elastomers (such as Viton) available to suit broad temperature ranges and media types
Media Compatibility: Compressed air and compatible inert gases
Typical Use Cases: Boosting pilot pressure for large pneumatic actuators / Fast actuation of large emergency shut‑down valves (ESD) / High‑capacity control valve systems
Robust Industrial Construction: Designed for frequent cycling, durability, and long service life in harsh environments
