BP - 66 - High Pressure Back Pressure Regulator, Maximum 10,000 psig

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.
