带手动开关电磁阀

产品描述 Product Description

进口带手动开关电磁阀主要用于电磁阀线圈失电或烧毁时，可用手动柄实现电磁阀打开和关闭；操作方便、性能稳定；活塞（膜片）结构、密封性好；精制线圈、不易烧毁

The imported solenoid valve with manual switch is mainly used to open and close the solenoid valve with a manual handle when the solenoid valve coil loses power or burns out; Convenient operation and stable performance; The piston (diaphragm) structure and sealing performance are good; Refined coil, not easily burned

工作原理 working principle

常开式:阀需自动控制时,手动柄必须处于打开状态;当线圈失电后,旋转手动柄可控制阀开关 Normally open: When the valve needs automatic control, the manual handle must be in the open state; When the coil loses power, rotating the manual handle can control the valve switch

常闭型:阀需自动控制时,手动柄必须处于关闭状态;当线圈失电后,旋转手动柄可控制阀开关 Normally closed type: When the valve needs automatic control, the manual handle must be in the closed state; When the coil loses power, rotating the manual handle can control the valve switch
