Mechanical design
Butterfly valve
 
Ring structure, with a cast-iron framework of ethylene-propylene-diene rubber inner layer.
 
The valve has a disc that can rotate fully. It is applicable to air-tight seal, and complies with DIN 3230 Standard.
 
The valve disc and shaft from DN40 to DN200 are made of stainless steel, and the valve disc exceeding DN250 is made of nickel-plated steel, and the shaft is sealed with a double O-ring.
 
Meanwhile, the inner layer is also used to seal the flange. In this way, there is no any contact between media and framework.

Maintenance
  
 
VKF46…series of butterfly valves do not need maintenance.
  
Warning
Before repairing the valve, actuator and/or mounting appliance, the following sequence must be complied with:
  
 
Turn off the water pump and cut off the water pump power source; close the stop valve in the pipeline, release the pressure of pipeline and cool the pipeline totally; if necessary, remove the electrical wiring from connection terminal. Before re-debugging the valve, it is required to mount the hand operated regulator or actuator correctly.
