D-1/2"-4-BRZ/BRZ/B2/2-15psi
The Model D-4 is primary a general gas service, self-contained, pressure reducing regulator. One of the most versatile regulators on the market, this Model D is excellent for atmospheric industrial gases – GN2, Ar, He, H2, CO2 – as well as natural gas pressure reducing 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 services are possible depeding on material compatibility.
This unit handles inlet pressures up to 51 Barg and outlet pressure is adjustable from 2-15 psig (0.14-1.0 Barg).
Comes with various options to choose from, Locking lever, Special cleaning for Non-oxygen Service, Gauge ports, Atex and PED Certificates
