Forged Cryogenic Globe Valve
Forged Cryogenic Globe Valve,justlikeCastSteelCryogenicGlobeValve, has a very reliable medium cutoff function. Once in the open state, there is no more contact between its valve seat and the sealing surface of the disc, so its 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 undernot high adjustment accuracy requirement , and the pipe diameter is relatively small size.

PRECAUTIONS FOR FORGED CRYOGENIC GLOBE VALVE：
1. Pls pay attention to the switch position problem of this valve.
2. Forged Cryogenic Globe Valve must be closed during maintenance to ensure that the grease fills the sealing groove along the sealing ring. Otherwise, the sealing grease will directly fall into the flow channel or valve cavity, causing waste.
3. When the valve is greased, grease injection effect is often ignored as a problem. During the grease injection operation, the pressure, grease injection volume, and switch position are all normal. However, in order to ensure the effect of valve grease injection, it is sometimes necessary to open or close the valve to check the lubrication effect to confirm that the surface of the valve disc is evenly lubricated.
