3/4" Stainless Steel Latching Solenoid Valve – Shako LSPU225A-06
The Shako LSPU225A-06 is a 3/4" BSP 316 stainless steel latching solenoid valve designed for low-power operation in water, air, gas and fluid control applications. Using a bi-stable latching coil, the valve requires only a short electrical pulse to change state, remaining open or closed without continuous power consumption. This makes it ideal for battery-powered systems, remote installations, water management equipment and energy-efficient process control applications.
