1½" Plastic Water Solenoid Valve 0.3–10 Bar Normally Closed
The GP40 Series is a high flow pressure assisted 2/2 way normally closed plastic water solenoid valve designed for reliable control of water and compatible low viscosity fluids. Manufactured with a reinforced nylon body and stainless steel internal components, the valve incorporates an adjustable manual flow regulator with anti-water hammer design, providing smooth operation while reducing hydraulic shock in larger pipework systems.
Designed for irrigation, water treatment, industrial water distribution and filling systems, the GP40 requires a minimum pressure differential of 0.3 Bar and offers working pressures up to 10 Bar. Standard, high power and optional ATEX certified coil options are available.
