RETZ工业/美国瑞茨，我们一直致力于流体控制领域的持续创新，始于2005……流体粘度通常在50cst 以下可以任意选择，若超过此值，则需要选择高粘度电磁阀 Retz The fluid viscosity isusually below 50cst and can be arbitrarily selected. If it exceeds this value,a high viscosity solenoid valve needs to be selected
进口高粘度电磁阀工作原理-Workingprinciple of imported high viscosity solenoid valve
常闭式：Normallyclosed
当线圈通电时，先导阀芯吸合，先导孔打开，阀上腔卸压，活塞靠下腔介质压力推动，电磁阀打开。当线圈断电时，先导阀芯靠弹簧复位，先导孔关闭，阀上腔由活塞节流孔增压和复位弹簧的推力，电磁阀关闭。
Whenthe 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 themedium pressure in the lower chamber, and the solenoid valve opens. When thecoil is powered off, the pilot valve core is reset by the spring, the pilot holeis closed, and the valve upper chamber is pressurized by the piston orifice andthe thrust of the reset spring, and the solenoid valve is closed.

注：出口端压力大于进口端压力，介质会反向导通。可安装止回阀 Note:If the outlet pressure is greater than the inlet pressure, the medium willconduct in the opposite direction. Can be installed with a check valve
