2.6
The use of the valve with adhesives, glues or general fl uids must be respect the following basic rules.
a specifi c type of fl uid check that:
• The fl uid viscosity is compa ble with the features of the valve
• The characteris cs of the fl uid meet the desired requirements
• The datasheet of the fl uid provided by the manufacturer includes all the informa ons about the
fl uid such as: viscosity, applica ons, gluing me (for glues or adhesives) and storage
• The storage me of the fl uid has not been exceeded
• The fl uid has not been exposed to temperatures near or below than zero therefore it has
deteriorated
• The packaging of the fl uid are sealed
For the use of we recommend to contact the Zator company to
verify the compa bility of the applica on.
Before use a diff erent type of fl uid clean accurately the valve to avoid possible contamina on of the
