Low temperature solenoid directional valve is widely used in natural gas, liquefied gas pipeline, and its role as same to other varieties of solenoid operated hydraulic control valve are as for the normal transport of the gas medium in the pipeline, necessary to cut off and the role of regulation on the flow. The low temperature solenoid operated hydraulic control valve is used in a number of highly flammable gas pipeline, so in the connection of the pipeline, need to ensure that the gas will not leak. The main reason of low temperature solenoid valve leakage is:

There are two reasons for the leakage of low temperature solenoid operated hydraulic control valve, firstly the main reasons is the seal deformation in the low temperature state. When the temperature of the medium is decreased, the volume change is caused by the phase change of the material, and the sealing surface with high grinding precision is produced to cause warpage, leading to the bad sealing. Two is the external leakage. It is mainly due to the flange connection between low temperature solenoid valve and pipe, due to the connection pad, connecting bolts, and the connection between the material at low temperature shrinkage caused by the relaxation of the gap and lead to leakage. Therefore, the connection mode between the valve body and the pipeline can be changed to the welding structure, then the low temperature leakage can be avoided. Another is the stem and packing leakage. These are the main reasons for the leakage of low temperature solenoid operated hydraulic control valve.
