Piston-Operated Diaphragm Valve
Repair/Maintenance
Stop fluid supply and control fluid supply and
reduce pressure in the pipe system, before opening
or repairing the product.
• Check diaphragm on wear after max. 100000
cycles.
! Slurry or abrasive fluids and high fluid temperatures
ask for accordingly shorter examination intervals.
Storing
If the valves are intended to be stored for longer
periods, the body screws must be loosened.
Otherwise this could result in diaphragm deforma-
tions due to lack of fluid pressure.
Electrical connection
Observe voltage and current type as specified on
the type label, voltage tolerance ± 10%.
Specifications in the data sheet and the operating
instructions of the pilot valve must be observed.
Spare part kits
One seal kit, diaphragm or body can be ordered
as spare parts.
