Pressure Relief Valve, Diaphragm Style, Nylon, 1/2" NPT, 1/4" FPT Gauge Port

Manual pressure relief valves from Spraying Systems are designed to bypass excess liquid within the supply line. Each diaphragm pressure relief valve can be manually adjusted to maintain control of line pressures at any pressure within the valve's operating range. These diaphragm relief valves feature nylon bodies, aluminum bonnets, and stainless-steel springs responsive to set pressures. A fairprene diaphragm enables wide chemical compatibility while extra-large valve passages handle full flows from the supply line. A positive locking nut ensures any adjustments are held firmly in place and not affected by vibration or jarring. This 1/2" relief valve features 1/2" NPT ports and a 1/4" gauge port.
