The integration of control valves into the DCS technology determines the accuracy of the control loop and impacts on the cost and quality of the final product. This integration is a prerequisite for effective preventative maintenance of control valves. It also adds to the availability of the system.

The pneumatic volume booster is mounted between the positioner and actuator. It supplies the actuator with an air flow output whose pressure corresponds exactly to the signal pressure, except that it has a much higher volume output.

  • Pneumatic volume booster

  • Compact aluminum or stainless steel body

  • Suitable for safety-instrumented systems

  • Fast dynamic response due to low hysteresis

  • Bypass restriction with linear characteristic

  • Bypass restriction setting can be lead-sealed

  • Sintered PE filter disk ensures low noise emissions

  • Constant reversing pressure
