DN08/10/15/20/25/32/40/50 AC 110V AC 220V DC 12V DC 24V Plastic normally closed solenoid valve water valve switching valve _x000D_ _x000D_ Dear buyer friend: _x000D_ _x000D_ Welcome to our store, this solenoid valve has two options, you need to know before buying, choose the right one for you. _x000D_ _x000D_ Ordinary coil Applicable to a single power-on time of less than 1 hour, more than 1 hour, the coil will generate heat, easy to damage; _x000D_ _x000D_ Not hot coil Not hot coil Applicable to the energization time of more than one hour, the coil will not heat for a long time; it saves electricity, which is equivalent to 1/5 of the power consumption of ordinary solenoid valves; there is almost no magnetic leakage noise.With an external energy-saving module, it is suitable for continuous opening for 24 hours without burning. If the power-on time is less than 1 hour, it is recommended to choose a cheap solenoid valve. _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ Choose the right product for your use. Short-term turn-on selection is economical and cheap, and long-term selection of better quality coils. _x000D_ _x000D_ _x000D_ _x000D_ Working principle: the valve is opened when the power is turned on, and the valve is closed when the power is turned off. _x000D_ _x000D_ Installation steps: _x000D_ _x000D_ _x000D_ 1.The threaded interface around the ribbons _x000D_ _x000D_ _x000D_ 2.According to the direction of access to the solenoid valve _x000D_ _x000D_ _x000D_ 3.According to the standard access power supply _x000D_ _x000D_ _x000D_ 4.Detection of sealing and circuit _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ Install the matters needing attention: _x000D_ _x000D_ 1.Before installation should keep clean pipeline _x000D_ _x000D_ 2.Be sure heart when installing electromagnetic in the pipe threads on the appropriate _x000D_ _x000D_ raw materials and adjust the position of the electromagnetic _x000D_ _x000D_ 3.Pay attention to the insulation of the circuit _x000D_ _x000D_ 4.Please install the electromagnetic direction according to the flow direction _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_
