Direct-operated solenoid valve WL2727

2-waynormally closedfor water

Product Overview
An irrigation solenoid valve WL2727 is an electrically operated control valve designed for automated water distribution in irrigation systems. It connects to a controller or timer and opens to allow water flow when energized. The valve includes a waterproof solenoid coil, a reinforced nylon or brass body and a rubber diaphragm for flow regulation. Available in multiple sizes (1/2", 3/4", 1") and voltage options, it is intended for stable outdoor use and long service life.

How It Works
The solenoid coil generates magnetic force when energized, lifting the plunger to open the diaphragm and permit flow. The coil is sealed for outdoor operation. Proper supply voltage and adequate inlet pressure are required for reliable actuation.

Voltage & Power

• Typical operating voltages: 3V, 6V, 12V, 24V.
• Models available in AC and DC variants (including 24V AC).
• Select voltage according to controller compatibility and power availability.

Applications

• Garden and lawn irrigation systems
• Agricultural field irrigation and pivot/drip systems
• Greenhouse irrigation for plant moisture control
• Landscape irrigation for parks, golf courses and large-area systems
• Integration with smart controllers/timers for water optimization

Advantages

• Enables automated, scheduled watering without manual operation.
• Low-voltage options improve safety for field installations.
• Waterproof coil allows reliable outdoor performance.
• Fast switching and stable flow control for precise irrigation cycles.
• Compact design simplifies installation in manifolds or pipework.
• Available in plastic (reinforced nylon) or brass for corrosion resistance.

Disadvantages

• Requires electrical power; not suitable where power is unavailable.
• Minimum inlet pressure needed; low pressure may prevent opening.
• Sensitive to particulate contamination; filtration recommended.
• Continuous coil energization increases heat and power consumption.
