These valves are constructed entirely of corrosion-resistant materials that comply with NACE specification MR0175/ISO 15156. These new check valves feature a durable MP35N poppet and seat, and are designed for checked direction pressures up to 15,000 psid.
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.
