Back Pressure Regulator 6000 psi: 1/4 in FNPT to 1/4 in MNPT


Anodized aluminum back pressure regulator, 1/4 in FNPT to 1/4 in MNPT. Maximum rated pressure: 6000 psi (414 bar). Fixed outlet pressure: 1900 psi (131 bar). In operation the back pressure regulator maintains its set pressure upstream and allow just enough gas flow to hold this pressure. Set pressure is pressure at the inlet port when gas is flowing through the regulator. The gauge connected to the outlet gauge port does not read set pressure; it reads pressure of the tank being filled downstream of the regulator.


Also known as a priority valve, the model 1310 is a fully balanced, economical regulator. It serves a wide variety of uses, however its main use is on small compressors. The regulator will improve moisture separator efficiency and filter life as much as 450%. This is done by maintaining pressure in the separator and filter at about 1800 psi when tank pressure is lower.
