Pilot-operated solenoid valve WL0102

2-wayairfor water

Overview
The WL0102 watering solenoid valve is an electrically actuated valve designed to automate water distribution in irrigation systems. It is compatible with timers and controllers and operates on low voltage for safe, low-power outdoor use. The valve is available with waterproofing options and materials selected for corrosion resistance, enabling outdoor installation.

Design & Features

• Low-voltage electric operation with low power consumption.
• Waterproof design suitable for outdoor installation (IP65 or IP67 depending on model).
• Constructed from durable plastics (e.g. nylon) with brass or stainless-steel components for corrosion resistance.
• Compact form factor with standard threaded connections for integration into irrigation piping.
• Diaphragm-based internal design and optimized flow channels to reduce pressure loss and extend service life.
• High sealing performance to minimise leaks.
• Compatible with mechanical timers, electronic controllers and smart/WiFi controllers for automated scheduling and sensor-driven irrigation.

Applications

• Automatic garden irrigation systems (sprinklers, drip lines).
• Landscape irrigation and multi-zone watering control.
• Agricultural irrigation systems for crop watering.
• Greenhouse irrigation with soil moisture or humidity sensor integration.
• Lawn irrigation, nurseries and other automated plant-watering solutions.

Advantages / Disadvantages
Advantages

• Automates watering according to preset schedules or sensor inputs, reducing manual intervention.
• Improves water efficiency by supplying water only when required.
• Low-voltage operation increases safety for outdoor installations.
• Compact and easy to integrate via standard threaded pipe connections.
• Reliable operation and long service life when installed and maintained correctly.

Disadvantages

• Requires power to operate; irrigation stops during power outages unless backup power is provided.
• Requires a minimum inlet pressure to function correctly.
• Sensitive to dirty or debris-laden water; particles can obstruct or damage the diaphragm.
• Quality of waterproofing and materials is critical; low-quality units may leak or fail prematurely.
