5 Maintenance
Maintain the valve/actuator regularly. Study the instructions carefully and pay special attention to the warnings!
Always keep spare rubber seals and guide rings in stock. The items refer to the parts list and service kits section.
The valve is designed so that internal leakages do not result in the products becoming mixed.
Internal leakage in the valve is externally visible. Check the valve for smooth operation after service.
