Aqua Environment aluminum high flow reducing regulator. 1/2" NPT outlet; 1/4" NPT inlet. Outlet pressure range: 0–1500 psi out. Maximum pressure rating 6000 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.
