Model 1325, 3-Way Solenoid Valve
3/8”, 1/2”, 3/4” Pipe Size, Pilot Operated
DESCRIPTION
Model 1325 three-way solenoid valves are available in brass or 304 stainless steel bodies. A choice of seal and seat materials including Acrylo-Nitrile and Viton® satisfy many general industry applications. The valve’s typical uses include lubricated and dry air, water, light oils and other compatible media.
The valves have a metal core diaphragm and pilot operated action. The pilot orifice has internal discharge so it may be used with fluids that cannot be discharged into the atmosphere. They have a greater flow capacity and faster response time than slide valves of the same size.
Options include weather proof housing, energized coil indicator light and manual override.

| Piloted valves use the fluid pressure to assist in opening and closing the valve, allowing the valve to operate against higher pressures than a direct acting valve.
When the pilot valve is closed, the pressure builds up via a small passage from the upstream side of the valve piston/seat. The valve seat is also acted on by a spring.
When the pilot valve opens, a passage that bypasses the valve piston/seat and connects downstream of the piston/seat is opened, relieving pressure from the top of the valve piston/seat. The inlet fluid pressure lifts up the piston to open the valve.
