Product Overview
This pressure regulating valve is constructed to use in agricultural spraying applications. This is an inline valve with a 3/4 in. male NPT inlet and a 3/4 in. female NPT outlet. The body of the diaphragm valve is constructed of nylon for chemical compatibility.

Built for performance, the diaphragm pressure relief valve can handle flow rates up to 70 gpm and pressures up to 300 PSI. The diaphragm is actuated by an adjusting screw with a handle for easier operation. The adjusting screw employs two stainless steel springs to operate the diaphragm assembly. The screw adjustment is held in place by a locking nut so your pressure will not fluctuate during operation.
