FUNCTION |
|
|
| 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.

INSTALLATION RECOMMENDATIONS
Place a strainer with a porosity < 100µ upstream of valve (see Clark Solutions Model 1359 Y Strainer).
Install valve in any position, preferably on a horizontal pipeline with coil up.
