If you're looking to gain more control over spray line pressures, this diaphragm-style 3/4" 300 PSI relief valve can help. With this nylon and aluminum relief valve in place, excess liquid returns back to its source instead of being wasted because of elevated pressure. Optionally add a pressure gauge to the open port.

Bypasses excess liquid. Adjustable to maintain control of line pressure at any pressure within the valve's operating range. Selected pressure setting firmly held in place by locknut. Extra large valve passages to handle large flows. Features: Diaphragm design pressure relief valve. Aluminum housing with nylon inlet body. Fairprene® diaphragm seals off all working parts from contact with liquid and provides responsive, chatter-free operation. Features additional port for pressure gauge installation.
