BP-66 Series Back Pressure Control Regulators
General Details
The BP-66 Series, counterpart to the PR-56 Series pressure reducing regulator, is designed for systems that are higher in pressure and have low to moderate flows. This regulator has a piston sensor assembly for maximum ease of adjustment to provide relief at high pressures. A carefully engineered piston sensor assembly affords excellent sensitivity and a wide selection of control ranges make this regulator an excellent selection in many research and pilot plant facilities.

Maximum Temperature & Control Pressures
| Seat Material | Maximum Temperature* | Maximum Control Range | |
|---|---|---|---|
| Polyimide | 350° F (176° C) | @ | 10,000 psig (68.8 MPa) |
