Miniature relief valve ensures zero leakage

A new miniature relief valve which is ideally suited for thermal relief and low flow hydraulic pressure relief applications where zero leakage is essential, is the latest addition to the established range of LEE PRODUCTS miniature components.  

The Lee 281 zero leak relief valve is designed for applications such as aircraft cowl door mechanisms where it will prevent leakage of oil onto a runway when operating at normal system pressure, but will activate overboard in an emergency, at higher pressures.  

The cracking pressure of these valves is preset at the factory with capabilities ranging from 1300 psid up to 4700 psid and ensures zero leakage in a one minute test; one drop per hour maximum. The valve provides typical flow rates ranging from a few ml per minute for thermal relief applications and up to 250 ml/min for low flow pressure relief applications.  

These valves, which weigh-in at only 6 grams, are 100% tested and inspected and are designed for operating temperatures of between -65ºF to +275ºF.
