WRAS Latching Solenoid Valves

WRAS Latching Solenoid Valves Browse WRAS approved latching solenoid valves designed for potable drinking water systems and low power control applications. Latching (bi-stable) solenoid valves use a short electrical pulse to change position and remain open or closed without continuous power, making them ideal for battery-powered systems, remote installations and energy-efficient water control. This range includes WRAS approved valves in brass, stainless steel and plastic, with voltages from 3V to 24V DC and sizes from 1/4" to 2" BSP. All valves comply with UK Water Regulations for safe use with drinking water. Unlike standard solenoid valves, latching valves only require power during switching, reducing energy consumption and making them ideal for off-grid, smart control and battery-powered water systems. Key Features: → WRAS approved for potable drinking water → Latching (bi-stable) operation → Pulse controlled (no continuous power required) → Low power 3–24V DC options → Brass, stainless steel & plastic bodies → Sizes from 1/4" to 2" BSP → Ideal for battery & remote systems → Suitable for irrigation, smart control & automation → Fast UK delivery
