This company’s Zero Leak Check line of check valves (photo) now includes new valve configurations that are manufactured entirely from materials that are compliant with the National Association of Corrosion Engineers (NACE) specification MR0175/ISO 15156. They also feature custom polymeric valve seats that ensure no leakage of fluids at pressures up to 15,000 psi (differential) and at temperatures up to 400ºF. The valves are also self-retained without the need for O-rings, facilitated by the use of a locking end that securely locks the valves in place and prevents any bypass leakage. Available with diameters from 0.187 to 0.500 in. (4.75 to 12.7 mm), configurations may also include integrated safety screens or restrictors for added protection and performance. These NACE-compliant valves are useful in applications that require zero leakage at high differential pressures in high-temperature, corrosive environments. — Lee Products Ltd., Gerrards Cross, U.K.
