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 dangerous
materials.
The safety information does not take into account:
•Unexpected incidents and events, which may occur during
installation, operation and maintenance.
•Local safety regulations which must be adhered to by the
operator and by any additional installation personnel.

3.2 Description
The GEMÜ 717 2/2 or 3/2-way plastic ball valve has an ergo-
nomically designed hand lever and is manually operated. 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 equipped
with a plastic manual operator. The threaded connection lock-
ing device enables the unions to be locked in place.
The valve body and the seal material are available in various
designs as shown in the datasheet. Optional accessories are
available on request (see chapter "Accessories").
