6.14 SCDLS VALVE INSPECTION

Diaphragm, pilot, and drain valves should be inspected annually to ensure maximum operating life of
the valves and to minimize maintenance costs.
!!! WARNING !!!
Take all appropriate precautions for working on equipment suspended from overhead. Failure to take
prudent safety measures can result in serious injury or death.

6.14.1 Diaphragm Valve Inspection

Filter
Access Panel
1. Unbolt the diaphragm valve from the header and remove the valve from the SCDLS
by sliding it up off the blow tube.
2. Open the valve casing by removing the bolts from the top of the valve.
3. Look for signs of moisture in the valve, which could indicate that the drain valve is
faulty or that the supply air is not being properly conditioned. The presence of
moisture can drastically reduce performance and life of the diaphragm valves, filters,
and headers.
4. Visually inspect all interior surfaces of the valve and clean using a brush or damp
cloth. Remove any remaining debris using compressed air.
5. Inspect the diaphragm. If torn, punctured, or worn, it should be replaced. (For
replacement parts contact PEBCO® at (800)707-3226).
6. Inspect the inlet and outlet seals and replace if necessary.
7. Reassemble the valve.
