This rugged, reliable electric solenoid valve operates on 24VAC power. This globe and angle configuration valve has 2" fpt inlet and outlet connections. The valve has a capacity of up to 150 gpm with only 11.5 psi pressure loss. This electric valve is used for cooling systems that require very high volumes of water. It can be used in conjunction with the Adjustable Pressure Regulator, P/N 2100-5238-200. This allows you to set the pressure for each zone at a level just high enough to open the check valves and provide a consistent spray pattern. This is very useful on long runs with sloped lines.
