Cryogenic Globe Valve


Description of Cryogenic Globe Valve:

ZECO cryogenic globe valve is available in low temperature -196 ℃ ultra-low torque which under the condition of low temperature and stable operation, and validated the sealing material of low-temperature materials also ensures ZECO cryogenic globe valve can be in extreme cases, good sealing performance and long service life and ZECO is a professional exporter of cryogenic globe valve, the products are widely used in LNG, LPG and other industrial conditions at low temperature. Cryogenic globe valve storage is also very important, If you want a few weeks or months to storage valves, need to cost for improving the original  storage conditions. Valve usually storage indoor, make the actual temperature of valves is higher than dew-point temperature. If the valves must be storage outside, It should be supported, not to contact with ground, and use waterproof cover to prevent.
