Product Description
The 3013-E4 two-way solenoid valve is a normally open industrial automatic control valve. The product is made of stainless steel 316 valve body material, with a diameter of DN14mm. It is designed to operate in a mode where the valve opens when not powered on and closes when powered on. This product is developed specifically for working conditions where it needs to be kept open for a long time and only requires intermittent power on and off, effectively reducing coil heating and energy consumption, and extending the overall service life of the solenoid valve. Voltage coverage includes DC12V, DC24V, AC110V, and AC220V, suitable for various industrial control systems.
Normally open design, the best choice for long opening conditions
Unlike normally closed solenoid valves (which open when powered on and close when powered off), normally open solenoid valves remain fully open in the power-off state and only activate when the medium needs to be cut off. For production scenarios that require valves to be opened for a long time, such as continuous circulation of cooling water, constant ventilation pipelines, and continuous supply of media, the normally open design avoids the problem of coils being charged and heating for a long time, significantly reducing the failure rate and energy consumption. It is the optimal selection solution for such working conditions.
Stainless steel 316 valve body, corrosion-resistant and high-pressure resistant
The valve body is made of stainless steel 316 (0Cr17Ni12Mo2) material, which contains molybdenum element and has better corrosion resistance than ordinary 304 stainless steel. It can withstand weak acids, weak bases, salt solutions, seawater, and various water, gas, and oil media. Simultaneously possessing excellent pressure resistance, suitable for medium and high pressure pipeline systems, ensuring structural strength and sealing reliability under long-term use.
DN14mm diameter, abundant flow
The DN14mm caliber design takes into account both installation space and flow capacity. Compared to small-diameter solenoid valves, DN14 provides more abundant flow capacity and is suitable for liquid and gas pipelines with medium flow requirements, effectively reducing flow resistance and pressure loss.
Multiple voltage options, compatible with mainstream control systems
Supports four voltage specifications: DC12V, DC24V, AC110V, and AC220V. It can flexibly adapt to the output signals of PLCs, relays, microcontrollers, and various industrial control systems without the need for additional voltage conversion modules, reducing system integration costs.
Working principle of power-off opening (normally open)
Non powered state: The valve is in the open position inside, and the medium flows freely.
Power on state: The electromagnetic coil is excited, the valve core moves to the closed position, and the medium is cut off.
This feature endows the solenoid valve with a fail safe protection function - in the event of an unexpected power outage, the valve automatically returns to the open state, ensuring that the system will not shut down or cause safety accidents due to interruption of flow (such as equipment overheating caused by cooling interruption, or gas accumulation caused by ventilation interruption, etc.), adding a safety guarantee to the production process.

Applicable scenarios
Industrial cooling water circulation system
Used for automatic on-off control of cooling water circuits in large equipment, reactors, heat exchangers, etc. The normally open design ensures continuous flow of cooling water during normal operation of the system when powered on. Only under specific conditions (such as equipment shutdown or temperature reaching standards), the valve is closed to cut off the water flow, greatly reducing the energy consumption and heat generation of the solenoid valve when powered on for a long time.
Ventilation and exhaust gas discharge pipeline
Suitable for constant flow ventilation control of ventilation ducts and exhaust gas collection systems. The normally open type ensures the continuous operation of the ventilation system, and the power on shutdown can be used to temporarily cut off the airflow under specific working conditions. At the same time, the failure protection function that automatically opens when the power is cut off can prevent the risk of gas accumulation caused by unexpected power outages in fans or pipelines.
Continuous medium supply pipeline
Suitable for process pipelines that require long-term valve opening, such as continuous supply of lubricating oil, continuous dripping of chemicals, and continuous blowing of gases. The valve can only be electrically closed during equipment maintenance, material replacement, or process switching to achieve intermittent shut-off control.
Fire and safety sprinkler system
Applied in the fire water sprinkler system, the normally open solenoid valve keeps the pipeline unobstructed (or maintains pressure) in the absence of a fire alarm. When a fire occurs, it is powered on by an electrical signal to close or open (depending on the system design). Combined with the normally open type's power-off opening characteristics, it can still maintain basic safety functions in extreme situations.
Agricultural irrigation and automatic sprinkler irrigation for gardens
Used for partition control of large-scale sprinkler irrigation systems, the normally open type ensures continuous water supply to the main pipeline, and achieves rotation irrigation operation by closing specific partition valves through timed power on. Compared with the energy consumption scheme that requires long-term power on to maintain opening, the normally open type has more energy-saving advantages.
