Description Specifications Literature Description 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. Typical Applications Pilot plants Research labs Features and Benefits Spring-loaded piston sensor Gas and liquid service Viton® seals (other elastomers optional) Options Panel mounting Monel® and Titanium body construction Cv of 0.01 or 0.12 AN 10050-4, SAE J514, MS 33649 or ⅜" FNPT connections State of California Proposition 65 WARNINGCancer and Reproductive Harm - www.P65Warnings.ca.gov.
