HP to LP Storage Regulator 6000 psi > 400 psi CGA 347 | PB415-347-LP


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. Outlet pressure: 0–400 psi. Comes with CGA347 nut nipple and two (2) stainless steel, liquid-filled pressure gauges with 2.5 in dials; one reads storage pressure and one reads regulated pressure.


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.
