General Purpose - Type 51R
  The Bellofram Type 51R General Purpose Regulator offers a high-performance regulator in a compact, low cost package. It operates in output pressure ranges up to 100 psi, with a maximum supply pressure of 250 psi. Materials of construction include die-cast aluminum for the body, glass-reinforced thermoplastic polyester for the bonnet, acetal resin for the internals, BUNA-N for the diaphragm, gaskets, O-ring, and pintle valve.

This versatile regulator provides excellent regulation over a wide range of applications, including pneumatic instruments, controllers, chucks, and actuators. It can be through-panel mounted with the supplied mounting nut, bracket-mounted with the optional bracket or, due to its light weight, mounted by its ports.
