What is a Solenoid Valve? Types and Selection Guide
Hydraulic solenoid valve is the most critical component of automatic irrigation systems. Professional irrigation solution at every scale with 4 different solenoid valve types including threaded, angled flanged, cast iron, and pressure controlled, 9V DC Latch & 24V AC energy options, and a diameter range from ¾ inch to 10 inches.
Hydraulic Solenoid Valve: The Heart of Automatic Irrigation
A solenoid valve is a type of hydraulic valve controlled by an electromagnet (solenoid) coil. When an electrical signal is applied, a magnetic field is generated in the coil, causing the piston to move and open or close the valve. When the power is cut, it returns to its original position by spring force (NC — Normally Closed) or maintains its position with magnetic latching (Latch type).
In modern agriculture and gardening applications, solenoid valves of automatic irrigation systems are indispensable components. Thanks to their ability to be controlled remotely or automatically, they meet your plants' water needs at exactly the right time and in the right amount ensures your satisfaction. When used with wireless valve control units, it covers every area from field to greenhouse smart irrigation solutions offers.
With zone-based control capability, it optimizes water consumption by 30-50% in areas with varying irrigation needs. It enables more efficient use of fertilizers by plants through precise control in fertigation applications. Solenoid valves play a critical role in all irrigation methods such as drip irrigation, sprinkler irrigation, center pivot irrigation, and greenhouse irrigation.
