High Flow Reducing Regulator: 6000 psi In > 0–400 psi Out

Aluminum high flow reducing regulator. 1/2 in NPT outlet; 1/4 in NPT inlet. Maximum rated pressure: 6000 psi. Outlet pressure range: 0–400 psi. The model 873 is a piston type, hand loading, and self-venting regulator. It utilizes a balanced poppet design for high flow and minimum effect of inlet pressure on outlet pressure. The poppet assembly is contained in a cartridge with internal filtration for easy in-field changing.
