Description
1" Plastic Water Solenoid Valve 0.3–7 Bar Normally Closed
The GP25 Series is a robust 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 PA nylon body, brass and stainless steel internals, the valve incorporates an adjustable manual flow regulator with anti-water hammer design, providing smooth operation and reduced hydraulic shock.
Designed for irrigation, water treatment, filling systems and general water control, the GP25 requires a minimum pressure differential of 0.3 Bar and is available with standard, latching, high power or optional ATEX certified coils.
