?  

 Mount the preassembled gasket/ assembly tool 

C 9 together with two shim rings E to the shut-off 
assembly without removing the ass. tool 9

 Screw thread disk D with the help of a 

screwdriver into the shut-off assembly. 

 In order to check the thightness of the gasket C 

check the mobility of the assembly tool 9. The 
gasket must keep the ass. tool in place, but the 
ass. tool must be smooth running. 

 If the gasket is too tight then remove a shim ring. 

Repeat this until the ass. tool is smooth running. 

 If the gasket is too loose then add a shim ring. 

Repeat this until the ass. tool is smooth running. 

 Mount the actuator X to the preassembled shut-

off assembly. The ass. tool 9 will be pressed out. 

 Remove the assembly tool 9

 Wrap a PTFE sealing tape round the thread of 

the integrated non-return valve Z. 

 Mount the non-return valve to the shut-off 

assembly.
