5 Maintenance
Maintain the valve/actuator regularly. Study the instructions carefully and pay special attention to the warnings! Always use
Alfa Laval genuine spare parts, and keep spare rubber seals and guide rings in stock. 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.
Step 4
Never touch the cl
ip assembly or the actuator piston rod if the
actuator is supplied with compressed air (see the warning label).
