3/4 Water Solenoid Valve 0.5-10 Bar WRAS 3v 6v 12v Latching

Description

3/4 inch WRAS brass latching solenoid valve – Model LPU225D-06

A WRAS approved, bi-stable (latching) 2/2 way normally closed brass solenoid valve designed for potable water applications where ultra-low power consumption and secure shut-off are required. The valve remains in position without continuous power and uses short polarity-reversing pulses to open or close, making it ideal for battery-powered and remote installations.
