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

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.

"A" Dimension does not include the "MS" Mounting Stud (Approx. 7/8")
Note: The addition of any bottom mounted option would replace the "MS" Mounting Stud and change the prefix to reflect the appropriate option.
