Check the diaphragm valves regularly for proper operation in terms
of assembly, installation and operation. Take the following factors into
account when planning servicing intervals:
• Operational conditions (amount of usage, improper usage),
• manufacturer's specifications in the technical documentation (e.g.
mechanical service life,
• major system modifications.
11.3. servicing work
Do not repair the device yourself, but replace it with an
equivalent device. Repairs may be performed by the manu-
facturer only.
11.3.1. actuator

If leakage occurs replace the diaphragm (see chapter "12. Repairs").
A bulging diaphragm may reduce the flow rate.
The replacement of the diaphragm is described in chapter
"12. Repairs".
11.4. cleaning
note!
avoid causing damage with cleaning agents.
▶ Before cleaning, check that the cleaning agents are compatible
with the device materials.
Observe instructions on operation in an explosion-risk (Ex)
area. See chapter "3.1. Use in Ex area"
.
Actuator
Clean the actuator surface using a moist cloth. Only use cleaning
agents that do not attack the actuator surface.
Body / Diaphragm
The bodies are suitable for CIP. Clean the valves using cleaning
agents that do not attack the body and diaphragm materials. Avoid
cleaning agents with high pH values.
