The Type 79 1:1 Ratio High Flow Precision Air Relay brings additional precision and control to the Bellofram line of precision control products. The Type 79 relay is designed for applications where a precise control of flow is needed. This regulator offers low droop, high accuracy, and fine adjustment sensitivity. The use of a Bellofram rolling diaphragm provides greater sensitivity and improved accuracy. The balanced pintle minimizes output pressure changes caused by fluctuations in supply pressure. The Type 79 is designed to regulate output pressure up to 200 psi with a maximum supply pressure of 400 psi.

Careful design and quality materials throughout assure long, trouble-free operation. The rugged die-cast zinc and aluminum housings are pressure tested to assure safe operation. The Type 79 model is designed to withstand harsh and abusive environments. This is attributed to a chemical conversion coating of all cast components, and a vinyl paint finish. The Type 79 can achieve forward flow rates of up to 275 SCFM. It is available in 3/8", 1/2", 3/4", and 1" NPT port sizes.
