Description
The Type 78 Direct Acting Air Pressure Regulator designed from Bellofram PCD is design to offer high-accuracy, large flow and exhaust capabilities within OEM and industrial applications. Available in five different pressure output ranges to 125 PSIG (8.6 BAR), this precision regulator offers low droop, high accuracy and fine adjustment sensitivity with maximum supply pressure rated at 400 PSIG (27.6 BAR) and achievable flow rates of well over 200 SCFM.
The unique design of the Type 78 features a patented Bellofram rolling diaphragm, offering greater sensitivity and improved accuracy, along with low-friction operation and long useful service life. The Type 78 also offers low droop, fine adjustment sensitivity and a balanced pintle, which minimizes output pressure changes caused by supply pressure fluctuations. Careful design and use of quality manufacturing materials ensures long, trouble-free operation, along with a chemical conversion coating of all cast components and a vinyl paint finish. Additional optional features and accessories include low-bleed, non-relieving, square head adjustment, T-handle adjustment, tamper resistant cover, epoxy paint, tapped supply gauge port and tapped exhaust. Mounting brackets and repair kits are also available.
