A high pressure relief valve, specifically designed for flow control applications that require both a high relief pressure and a high flow rate in an ultra-compact package, has been introduced by LEE PRODUCTS. The Lee Hi-Q valve is capable of relief pressures up to 5400 psid and flow rates over 19 GPM and so is ideally suited to critical flow applications. These could, for example, include aero engine fuel pumps, aircraft flight controls, Formula 1 or rally cars as well as oil tool applications.

The innovative design includes a side inlet flow path which helps to minimise the installation boss size and weight, resulting in a valve which measures 98.5mm length x 23mm diameter and weighing just 200 grams.

The Hi-Q valve is available in a range of cracking pressures, from 1000 up to 5400 psid and is designed for nominal system pressures up to 5000 psi and system peak pressures up to 6750 psi. Each valve is 100% tested and inspected to ensure reliable and consistent performance in the most critical flow control applications.
