The Lee Co.’s Hi-Q Pressure Relief Valve is designed for applications that require both a high relief pressure and a high flow rate in a compact package. The relief valve is capable of relief pressures up to 5400 psid and flow rates over 19 gpm. The valve uses a side inlet flow path to help minimize the installation boss size and weight. The valve is offered in a range of cracking pressures from 1000 to 5400 psid. It is designed for nominal system pressures up to 5000 psi and system peak pressures up to 6750 psi. Every valve is 100% tested and inspected to ensure reliable, consistent performance.
