LNG Low Temperature Globe Valve

LNG Low Temperature Globe Valve

Working Principle of LNG Low Temperature Globe Valve:

The axis of the stem of the low temperature globe valve is perpendicular to the sealing surface of the valve seat. The opening or closing stroke of the valve stem is relatively short, and it has a very reliable cut-off action, which makes this valve very suitable for medium cut-off or regulation and throttling. Once the low-temperature globe valve is in the open state, there is no longer any contact between its seat and the sealing surface of the disc, so its sealing surface has less mechanical wear, because the seat and disc of most globe valves are easier to repair or When replacing the sealing element, it is not necessary to disassemble the whole valve from the pipeline, which is very suitable for the occasion where the valve and pipeline are welded together. The flow direction of the medium through this type of valve changes, so the flow resistance of the globe valve is higher than that of other valves.

Features of LNG Low Temperature Globe Valve:

1. The ability to work for a long time under low temperature medium;
2. The assembly directly in contact with the low temperature medium has an explosion-proof and fire-proof structure;
3. Materials working at low temperature should ensure their low temperature performance to prevent friction parts from being scratched;
4. In the case of low temperature and no oil lubrication, it has good abrasion resistance.
