Aluminum Reducing Regulator: 6000 psi In > 50–400 psi Out


Aluminum reducing regulator. 1/4 in FNPT fittings. Outlet pressure range: 50–400 psi. Maximum rated pressure: 6000 psi. The model 415 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.
