This is a high flow solenoid valve with a 40mm orifice and Cv value of 29. This means the valve can flow approximately 220 GPM of water at 60 PSI.
The 12 Volt DC coil is included and required 40 watts or 3.25 amps to actuate. The coil includes lead wires for easy connection. The coil is rated for continuous use but should not be powered indefinitely.
The valve body is made of 304 Stainless Steel and it uses a Viton Diaphragm. These components are food grade and this valve can be used for potable water applications.
