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 valve uses an elastomeric seat to achieve zero leakage. The remaining components are constructed entirely of stainless steel. The valve flows over 62 L/min. (air) at 25 psi difference, with a diameter of only 0.250 in. Nominal weight is 3.8 g, and maximum working pressure is 3,000 psi difference.

Used in combination with the StimMAP LIVE hydraulic fracture stimulation diagnostics service, which delivers microseismic data while the fracture treatment is pumped, StimMORE allows real-time optimization of fracture treatments.
