品牌：RETZ瑞茨/我們一直致力于流體控制領域的持續創新，始于2005……進口高粘度石油專用電磁閥活塞結構、動作靈敏、反應迅速、設計獨特、密封性好 High viscosity petroleum specialized solenoid valve piston structure, sensitive action, rapid response, unique design, and good sealing performance

電磁閥通常流體介質粘度在50cst 以下可以任意選擇，若超過此值，則需要選擇高粘度電磁閥Electromagnetic valves usually have a fluid medium viscosity below 50cst and can be selected arbitrarily. If this value is exceeded, a high viscosity electromagnetic valve needs to be selected

進口石油專用電磁閥工作原理Working Principle of Imported Petroleum Special Electromagnetic Valve

常閉-當線圈通電時，先導閥芯吸合，先導孔打開，閥上腔卸壓，活塞靠下腔介質壓力推動，電磁閥打開；當線圈斷電時，先導閥芯靠彈簧復位，先導孔關閉，閥上腔由活塞節流孔增壓和復位彈簧的推力，電磁閥關閉。Normally closed - when the coil is energized, the pilot valve core is closed, the pilot hole opens, the upper chamber of the valve is depressurized, the piston is pushed by the medium pressure in the lower chamber, and the solenoid valve opens; When the coil is powered off, the pilot valve core is reset by the spring, the pilot hole is closed, and the valve upper chamber is pressurized by the piston orifice and the thrust of the reset spring, and the solenoid valve is closed.
