The new valves are available in free flow forward and free flow reverse directions, with cracking pressures of 5 ± 3 and 1 ± 0.5 psid. Sizes range from 0.125” to 0.500” in diameter, with free flow Lohm† rates from 400 to 15 Lohms. Each NACE Compliant High Pressure Lee Chek® valve is 100% tested and inspected to ensure re- liable, consistent performance, eliminating the need for additional in-house testing.
