Bronze Solenoid Valve
Gritty Coolant Valves Full Port
Full Port - Normally Open - 1/2" to 1" Pipe Size
Max. Fluid Temp. - 212°F | Max. Static Pressure - 300 PSI
No Differential Pressure Required to Open
Operation
This solenoid valve closes when energized and opens when de-energized. When the coil is energized the plunger presses the poppet, closing the pilot orifice, and opens a bleed passageway to permit pressure to build above the piston and sealing it. Upon de-energizing the coil, the pilot orifice is opened, relieving the pressure above the piston, allowing it to leave its seat. The bottom spring allows the valve to operate at zero pressure drop.
Application
To control the flow of "Coolant", the valve is designed with the piston "turned down" and a larger pilot port, offering additional clearance, allowing the valve to operate with fluids containing some grit/sediment typically found in coolant. Valve operates from zero to maximum differential pressure indicated in table. Valve must be mounted in horizontal pipe with solenoid enclosure vertical and on top.
