RETZ/我們一直致力于流體控制領域的持續創新，始于2005……進口流體粘度通常在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 Retz The fluid viscosity is usually below 50cst and can be arbitrarily selected. If it exceeds this value, a high viscosity solenoid valve needs to be selected

進口高粘度電磁閥工作原理-Working principle of imported high viscosity solenoid valve

常閉式：Normally closed

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。

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.

注：出口端壓力大于進口端壓力，介質會反向導通。可安裝止回閥 Note: If the outlet pressure is greater than the inlet pressure, the medium will conduct in the opposite direction. Can be installed with a check valve
