BQ-1/2"NPT-5-BRZ/BRZ/B5/65-150psi, Cryo
The Model BQ is is primary a general service, self-contained pressure relief / pressure sustaining regulator suitable as a back pressure regulator or bypass valve for controlling inlet pressures between 65-150 Psig (4,48 - 10,3 Barg). For 1/2" (DN15) process piping and 1/2” (DN15) outlet connection.
With a large orifice and diaphragm provide sensitivity with high capacity. The composition seat allows for tight shut-off.
This Model BQ is excellent for both Cryogenic liquids and industrial gases – LOX, GOX, LIN, GN2, Ar, He, H2, CO2, CNG, LNG. Include Cleaned for Oxygen service, cryogenic construction.
Atex and PED Certificates upon request.
