Marsh Bellofram’s Type 51R High-Performance Low-Cost Precision Air Regulator provides high-performance in a compact, low-cost package, offering output pressure ranges to 100 psig; 6.9 BAR.

The maximum supply pressure is 250 psi (17.3 BAR). It is constructed of die cast aluminum for the body and dripwell; glass-reinforced thermoplastic polyester for the bonnet; acetal resin for the internals; BUNA-N for the diaphragm, gaskets and O-ring, fluorocarbon for the pintle seat, and aluminum for the drain valve (plated steel handle).

The Type 51R regulator offers superior regulation for a vast range of applications, including pneumatic instruments, controllers, chucks, and actuators. They can be through-panel mounted with the supplied mounting nut, bracket-mounted with the optional bracket or, due to their light weight, mounted by their ports. The Corrosive Tec is supplied with a tapped bonnet vent, to allow for the capture of exhaust air.
