Servicing  

6.1  Maintenance Instructions 

 

 

Caution – functional impairment or material damage! 

Inspection and maintenance intervals: 

 

Visual inspections must be carried out continuously every 4 weeks. 

 

To ensure that the valve is ready for operation and functionally reliable, it should be  

checked every year within the scope of the general internal maintenance procedure.  

       >>  Maintenance intervals must be set by the user  

 

After maintenance, always remove protective devices and reconnect the feed and drain 

lines to the valve. 

 

Ensure that a function test is always performed on the valve 

 

following maintenance work. 

6.2  Troubleshooting 

Malfunction  

Possible causes 

Measures 

Leak  

(external) 
 

  O-ring seals between  

flange and housing damaged  

  Screws have come loose 

  Process pressure too high 

 Replace seals 

 

 Test tightening torque 

 Check pressure   

Leak/backflow 

(internal) 

 

  
 

  O-ring seal between taper and shutter 

damaged 

  Seal area damaged 

 

  Shutter blocked 

 Replace seals 

 

 Check seating area and taper for 

mechanical damage 

 Manual functional check, remove 

shutter 

Noise generation 

  Uneven flow/cavitation 

 Check process conditions, 

change installation position

Seal replacement - please note the following points: 

 

Use a suitable tool (dig hook) to remove the seals 

 

The gasket grooves should be cleaned thoroughly before installing the new seals. 

 

Slightly grease the seals (only use grease approved for the field of food processing)  

 

Insert seals evenly into the gasket grooves
