P79 High Flow Air Relays
The P79 1:1 Ratio High Flow Precision Air Relay brings additional precision and control to the BelGAS line of precision control products. The P79 relay is designed for applications where a precise control of pressure is needed. This regulator offers low droop, high accuracy and fine adjustment sensitivity. The use of a rolling diaphragm provides greater sensitivity and improved accuracy. The balanced pintle minimizes output pressure changes caused by fluctuations in supply pressure. A version of the P79 for valve control applications is available. The P79 utilizes soft exhaust seats to minimize air consumption, increased deadband to ignore valve oscillations, and an integral bypass valve that can be ‘tuned’ for optimum valve response.
