8.2 Required Spare Parts
Under particularly harsh operating conditions, the sealing elements of the ROTADISK
Pneumatic Actuator can begin to show signs of wear after a certain time. Moreover,
very critical or extreme operating conditions with approx. 500,000 to 1,000,000 cycles
may necessitate periodic replacement of the ROTADISK Pneumatic Actuator
components.
Suitable spare parts are required for this repair work. Flowserve Flow Control GmbH
offers spare parts kits for every ROTADISK Pneumatic Actuator.
In order for Flowserve Flow Control GmbH to be able to offer suitable spare parts kits
for the ROTADISK Pneumatic Actuator, the ROTADISK Pneumatic Actuator must be
clearly identified.
This technical identification can be provided by the data on the nameplate.
8.3 Repairing the ROTADISK Pneumatic Actuator
Do not carry out your own repair work on ROTADISK Pneumatic Actuators
without consultation and support by Flowserve Flow Control GmbH because
the very size of the pneumatic actuator also presents a considerable danger.
The following repair instructions (installation and disassembly instructions) describe
the replacement of (worn) seals which are usually the reason for leakages.
Please note that these repair instructions describe the principal procedure for
replacing the seals of ROTADISK Pneumatic Actuators (RD/RDF 2,5–160) and that this
repair work entails considerable risks.
Do not carry out your own repair work on the ROTADISK Pneumatic Actuator without
suitable tools (e.g. an assembly device with press), original spare parts and prior
consultation with Flowserve Flow Control GmbH.
In case of damage, contact the Quick Response Center (QRC) of Flowserve Flow
Control GmbH.
