BelGAS 289 Series - P289RC High-Capacity Exhaust Booster
The P289RC is utilized in applications that require large pneumatic actuators and valve controls for rapid response. It is particularly well-suited for use with surge valves or recycle valves in compressor stations, accommodating compressor surges and sudden pressure fluctuations from output devices. The P289RC's 1/4” spring case port is connected to a controlling instrument, such as an I/P, Controller, or Positioner, while its 1” body port is directly connected to the actuator. For proper operation, it is essential to connect a bypass valve to the inlet and outlet of the P289RC at a location convenient for the end user. The exhaust booster of the P289RC opens further as the differential pressure across the bypass valve increases. The factory-set opening pressure of approximately 0.7 PSIG is not field-adjustable. As the differential pressure between the controlling instrument and the actuator decreases, the booster exhaust valve closes.
