The two-way valve cannot be used as three-way valve by disassembling the blank flange at the bottom of valve.













	
Notices

	 	  
	  	 	  
	
Engineering

	 	
It is suggested that the valve be mounted on the return water pipe, because in the heating system the temperature of return water pipe is relatively low. In this way, the service life of valve spool seal can be extended.


	  	 	
The water quality shall comply with VDI 2035 Standard.


	


	 	
It is suggested the filter be mounted in front of valve to increase the safety function of valve.


	  	 	  
	


	 	
When the medium temperature is lower than 0oC, select ASZ6.5 electronic valve handle heating element to prevent the valve spool within the sealing gland from freezing. For the sake of safety, the operating voltage of this heating element is designed AC 24V, and its power is 30 W.


	  	 	
VXI41... three-way valve is preferred as flow collecting valve.


	
Mounting

	 	
The valve and actuator can be assembled in the mounting position simply, without special tools and adjustment.


	  	 	
Instruction for Mounting shall be attached with when the valve is delivered. Its number is 74 319 0423 0.

Flow direction of media

	
During the mounting, pay attention to the mark of water current direction on the valve:













	  	
Two-way

	
three-way mixing

	
three-way diverting


	  	  	  	  
	  	


	


	








 



	
Debugging

	


	
Debug the valve only after the actuator has been mounted correctly.













	  	


	


	  











	  	
Valve handle contracts: flow increases, the pass valve open, bypass valve closed


	  	
Valve handle extends: flow decreases, the pass valve closed, bypass valve open













	
Repair

	


	
When repairing the actuator, comply with the following sequences: first turn off the water pump and cut off the water pump power source; close the stop valve, drain the water within the water pipe in order to reduce the pressure within water pipe, and cool the hot water pipe naturally. Remove the electrical wiring from connection terminal. Before re-debugging the valve, mount the actuator properly.


	  	  	  
	  	  	
When the water pipe has de-pressurized and cooled fully, and the valve handle surface is in good condition, it is allowed to replace the seal of valve handle directly, without removing the valve body. If the valve handle has been damaged, replace the whole valve handle-valve plug assembly. Please contact the local office or branch of Siemens Building Technologies.
