Irrigation valve RainPoint 1" DC Electronic Irrigation Valve BIV025ESC-DC

The RainPoint 1" DC Electronic Irrigation Valve BIV025ESC-DC is a 1-inch solenoid valve for garden and landscape irrigation. It operates on 9–24 V DC using latch (pulse) technology to provide reliable on/off control of water flow while minimising energy consumption. The valve supports pressures from 0.2 to 10 bar, is protected to IP68 and is suitable for automatic controllers, battery-powered systems and demanding outdoor installations.

Advantages

The latch coil design requires only a short electrical pulse to change valve state, which reduces power draw and extends battery life in off-grid setups. Robust construction and an IP68 rating protect the valve from moisture and harsh environmental conditions, while wide operating pressure and temperature ranges ensure stable performance in varied installations.

Suitable for

• Automatic garden irrigation controllers
• Drip irrigation lines and micro‑irrigation
• Sprinkler zone control
• Battery-powered or low-voltage irrigation systems

When it may not be suitable

This valve is designed for applications requiring a 1" BSP connection and DC latch control; it may not be suitable where different thread sizes or AC-driven solenoids are required. Systems that cannot provide the specified pulse duration or minimum capacitance may experience unreliable switching.

Key specifications

• Connection diameter: 1" (BSP)
• Operating voltage: 9–24 V DC (latch/pulse)
• Control type: Pulse (DC latch)
• Pulse duration: ≥200 ms
• Minimum capacitance: 4700 µF
• Operating pressure: 0.2–10 bar
• Operating temperature: up to 60°C
• Protection rating: IP68

How to use

Install the valve inline using compatible 1" BSP fittings and ensure secure, watertight connections. Connect the control wiring to a compatible 9–24 V DC latch-capable controller or driver. Provide a pulse of at least the specified duration and ensure the controller or power source meets the minimum capacitance requirement for reliable switching. Test the valve operation and check for leaks before leaving the system under automated control.

What to consider before purchase

• Compatibility with existing pipe threads and fittings (1" BSP)
• Controller capability to deliver latch/pulse control at 9–24 V DC
• Power source and capacitor capacity to meet the ≥200 ms pulse and 4700 µF minimum
• Required operating pressure and temperature range for your installation

Usage recommendations

For reliable long-term operation, use a controller or driver designed for DC latch solenoids, include the recommended capacitance in the power supply, and perform periodic checks for leaks and debris that could affect valve sealing.
