A Kind of High Pressure and Low Pressure Relief Valve Used in Oil Pipeline's Safety and Protection

In order to avoid damaging machine, pumps, valves and pipe by unexpected accidents at long distance oil pipeline. It is necessary to install safety and protection equipment for ensuring oil movement safely and smoothly. According to the spill valve principle of hydraulic system and high pressure valve imported at oil pipeline, we designed a kind of new safety and protection equipment pilot electric high pressure valve and liquid damping electric low pressure relief valve used in long distance oil pipeline.
