Reducing Regulator 6000 psi: 1/4 in MNPT x 1/4 in FNPT

Maximum rated pressure: 6000 psi (414 bar). Outlet pressure range: 0-5000 psi (0-345 bar).


The model 1120 is a small, piston type, hand load regulator available in an outlet pressure range of 0 to 5000 psi (0-345 bar) with a single inlet and outlet port. It is available with a hex head adjusting bolt and lock nut for single set pressure use or with the same adjusting hand knob. It can be panel mounted using either the upper 1.25" threaded section and lock nuts or the lower 1" jam nut. It 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 20 to 30 micron filter in the poppet cartridge prevents damage by contaminants.
