2 Safety information
The safety information in this document refers only to an indi-
vidual product. Potentially dangerous conditions can arise in
combination with other plant components, which need to be
considered on the basis of a risk analysis. The operator is re-
sponsible for the production of the risk analysis and for com-
pliance with the resulting precautionary measures and re-
gional safety regulations.
The document contains fundamental safety information that
must be observed during commissioning, operation and main-
tenance. Non-compliance with these instructions may cause:
– Personal hazard due to electrical, mechanical and
chemical effects.
– Hazard to nearby equipment.
– Failure of important functions.
– Hazard to the environment due to the leakage of dan-
gerous materials.
The safety information does not take into account:
– Unexpected incidents and events, which may occur
during installation, operation and maintenance.

the operator and by any additional installation person-
nel.
Prior to commissioning:
1. Transport and store the product correctly.
2. Do not paint the bolts and plastic parts of the product.
3. Carry out installation and commissioning using trained
personnel.
4. Provide adequate training for installation and operating
personnel.
5. Ensure that the contents of the document have been fully
understood by the responsible personnel.
6. Define the areas of responsibility.
7. Observe the safety data sheets.
8. Observe the safety regulations for the media used.

3.2 Description
The 2/2 and/or 3/2-way GEMÜ 710 plastic ball valve has a
pneumatic actuator, which can either be made from alu-
minium or plastic. The seat seal is made from PTFE and the
O-ring seals can be made from either EPDM or FKM.
3.3 Function
The product is a 2/2 or 3/2-way plastic ball valve. It has a low
maintenance pneumatic actuator. It has a low maintenance
pneumatic quarter turn actuator providing rotation through
90°. The actuator has an optical position indicator as stand-
ard.
The threaded connection locking device enables the unions to
be locked in place.
The ball valve body and the seal material are available in vari-
ous designs as shown in the datasheet.

4 Correct use
3.4 Port positions
The port position can be variably adjusted by the customer.
The actuator must be removed in order to do this. The shaft
extension of the mounting kit can be turned in any number of
90° increments, allowing for a customized port position. A
tool with an appropriate wrench size is required to turn the
shaft extension. This tool is not included in the scope of deliv-
ery. Once the desired adjustment has been made to the port
position, the actuator can be refitted.
