What Is The Function Of The SAVVY Cryogenic Piston Lifting Check Valve For CNG/LNG?

The SAVVY Cryogenic Piston Lifting Check Valve CNG LNG is designed to prevent backflow in cryogenic systems handling liquefied or compressed natural gas at extremely low temperatures, often as low as -196°C. Utilizing a piston-type lifting mechanism, the valve opens automatically when flow pressure is applied in the forward direction and closes quickly if reverse flow occurs, ensuring one-way operation. Its robust forged construction and cryogenic-rated materials provide exceptional resistance to thermal stress, making it ideal for LNG terminals, storage tanks, and transportation systems. The extended bonnet design insulates the stem area and prevents ice formation, preserving sealing integrity and operational safety. This valve’s precise movement and reliable sealing characteristics help maintain purity, pressure stability, and overall system efficiency in cryogenic gas handling. SAVVY’s engineering ensures consistent performance, long service life, and safety compliance in demanding low-temperature environments.
