Miniature check valves achieve zero leakage
Among the key requirements for components specified for critical 'hi-tech' flow control applications, such as fuel lines in aviation or formula one racing cars, are compact dimensions and low weight. To meet these demands, Lee Products has developed a range of flow restrictors and check valves that are claimed to be the smallest insert check valves available.
The latest addition to this range is a 250 zero leak check valve, which provides zero leakage flow control from 5-3000psid. Despite a diameter of only 0.250inch, length of 0.80inch and a weight of just 3.8g, these valves provide flows of over 62SLPM (air) at 25psid. Maximum working pressure is 3000psid.
250 Zero Leak Check valves are available in forward- and reverse-flow configurations and use an elastomeric seat to ensure zero leakage. Other components are constructed entirely of stainless steel.
Typical applications for these valves are in aerospace, oil tool, industrial gas turbines or other high-technology engineering sectors demanding critical flow control using the smallest, lightest components available.
