HP to LP Storage Regulator: 6000 psi In > 0-400 psi Out

Designed for regulating high pressure (HP) storage pressure to low pressure (LP) regulated supply. High quality, piston type, hand load reducing regulator. Inlet pressure: 6000 psi (414 bar). Outlet pressure: 0–400 psi (0-27 bar). Comes with CGA 347 nut nipple and two (2) stainless steel, liquid-filled pressure gauges with 2.5 in dials; one reads storage pressure (6000 psi / 414 bar) and one reads regulated pressure (400 psi / 27 bar).


The model 415 reducing regulator is a piston type, hand load regulator that uses an unbalanced poppet design for ruggedness and simplicity. There is a small variation of control pressure with changing inlet pressure as noted in the specifications. A 30 micron filter in the poppet cartridge helps prevent damage by contaminants.
