Forged Cryogenic Globe Valve,just like Cast Steel Cryogenic Globe Valve, has a very reliable medium cut-off function. Once in the open state, there is no more contact between it’s valve seat and the sealing surface of the disc, so it’s sealing surface is less mechanically worn, because most of the valve seats and discs are easier to repair or replace the sealing elements. There is no need to remove the entire valve from the pipeline, which is very suitable for the occasion where the valve and the pipeline are welded together. It is generally used in a working environment with flow adjustment or pressure adjustment under not high adjustment accuracy requirement , and the pipe diameter is relatively small size.

All metal parts are subjected to more than two deep cold treatments before finishing;
All extended valve stems (except check valves) are made of high-performance XM-19 or Inconel718 alloy materials;
All spheres are hardened and precision ground, with a surface accuracy of more than 0.2um;
All lip-seal seals are from international first-line brands;
All sealing surfaces that match the lip-seal are polished with precision technology to achieve a surface accuracy of more than 0.2um;
All "TEJI" brand cryogenic valves are tested for normal temperature and low temperature performance according to international industry standards before leaving the factory, and are shipped only after they pass the test;
All seals of the extended stem packing parts adopt a unique combined structure, which can not only ensure long-term sealing performance, but also reduce the switching torque;
All valves below -101℃ (except check valves) are equipped with cooling plates to effectively ensure that the temperature at the bottom of the packing is above 0℃; at the same time, it can effectively prevent condensed water from freezing on the valve body.
