BQ-1/2"NPT-45-55-BRZ/BRZ/B5/20-75psi, O2-clean
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 20-75 Psig (1,38 - 5,17 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 liquids and industrial gases – GOX, GN2, Ar, He, H2, CO2, CNG – as well as natural gas. Also, pressure sustaining applications where the temperature is greater -29 Deg C. Can be used as a utilities air regulator. Also, for use in corrosive and non-corrosive chemical gas and Liquid services are possible depending on material compatibility.
Other options available upon request include Cleaning for Oxygen service, cryogenic construction for LOX, LIN, LH2, LNG ect. and differential/pressure loaded construction.
Four body materials and twenty-one trim material combinations allow compatibility with many liquids and gasses. Atex and PED Certificates upon request.
