BP-66 Series Back Pressure Regulators On Circle Valve Technologies Inc.

The BP-66 Series is the counterpart of the PR-57 pressure reducing series for systems that are higher in pressure and low to moderate flows. This regulator has piston sensing to provide relief at high pressures. The Polyimide/stainless seat assembly provides good shutoff in most applications. For economy purposes the cap assembly and knob are of aluminum construction as in the PR-57 companion unit. Good sensitivity and a selection of control ranges make this regulator an excellent selection in many research and pilot plant facilities.

Features & Specifications

Spring-loaded piston sensor
Gas and liquid service
Viton® seals (other elastomers optional)
