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. |
