New Zero Leak Check Valve

The Lee Company’s new 250 Zero Leak Chek® is the latest addition to Lee’s line of miniature, zero leak check valves. Available in forward and reverse flow configurations, the new Lee Chek uses an elastomeric seat to achieve zero leakage. The remaining components are constructed entirely of stainless steel.

This new valve flows over 62 SLPM (air) at 25 psid, yet has a diameter of only 0.250”. Nominal weight is just 3.8 grams.

Each Lee Chek is 100% tested and inspected to ensure reliable, consistent performance. Maximum working pressure is 3,000 psid.
