The 1/2" 300 PSI Brass Relief Valve is reliable, durable, and easy to rebuild, making it useful for landscaping and agricultural spraying. The construction includes a brass seat for added and accurate pressure control. The side port of the unit functions as a return port to the tank, and the free-floating seat design increases overall regulator sensitivity and speed.
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. Also available in 3/4" and in 50 and 700 psi.
