Xiamen Superb Technology Co., Ltd. is one of the leading manufacturers and suppliers of 1 inch irrigation solenoid valve in China. As we have world-leading production equipment and strong manufacturing capabilities, we warmly welcome you to wholesale bulk premium 1 inch irrigation solenoid valve from our factory.
Product Details
This 1 inch irrigation solenoid valve is normally closed (automatically shuts off when no power is applied). The main body is made of reinforced nylon, which is UV-resistant, corrosion-resistant, and resistant to chemical fertilizers, making it suitable for recycled water and fertilizer-containing irrigation. The double-bead diaphragm design ensures zero leakage, withstands pressures up to 10 Bar, and has a long service life.
Compared to manual irrigation valve, this valve automates irrigation, improving water resource utilization. ISO quality certified, environmentally friendly and lead-free, it is suitable for sustainable agriculture and landscaping projects.

Working Principle

The 1 inch irrigation solenoid valve controls the pilot orifice via a solenoid valve, and the switch is driven by water pressure:
Closed (No Power): Solenoid valve de-energized, pilot orifice closed → Upper chamber fills with high-pressure water → Diaphragm tightly seals against valve seat → Water flow blocked.
Opened (Electrified): Controller signal → Electromagnetic valve magnetic field lifts plunger → Pilot orifice opens → Upper chamber drains → Lower chamber water pressure pushes diaphragm upward → Main valve seat opens → Water flow resumes.
Latching type: Short pulses reverse magnetic polarity to lock valve position, eliminating continuous power supply and achieving energy-saving benefits.
Why are solenoid valves necessary in irrigation systems?
Manual irrigation valves are complex to operate and cannot be automated.
Automation: Works with controller to enable timed irrigation, automatically adjusting based on crop water demand, soil moisture, or weather conditions.
Saving Water: Uniform water distribution enhances water and fertilizer utilization, boosting crop yields while reducing water waste.
Remote Management: Users can monitor and adjust settings anytime via the controller.
Energy Efficiency: Latching type is particularly suited for solar/battery systems, featuring extremely low power consumption.
