Zero leak check valves suit critical flow systems

To meet miniaturisation demands, component specialist Lee Products has developed a range of flow restrictors and check valves which are acknowledged as being the smallest insert check valves available
Among the important requirements for components specified for critical 'hi-tech' flow control applications, such as fuel lines in aviation or formula one racing cars, are "Make it smaller, make it lighter".
The latest addition to the Lee Products range is a Model 250 zero leak check valve, which provides zero leakage flow control from 5 up to 3000 psid.
Despite a diameter of only 0.250inch, length of 0.80inch and weighing just 3.8 grams, these valves provide flows of over 62 SLPM (air) at 25 psid.
Maximum working pressure is 3000 psid.
The 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 wherever high-technology engineering applications demand critical flow control using the smallest and lightest components available.
