LDK-4

The flange-throttle valve type LDK-4 is mounted between flanges according to DIN 24154 T2R2 in pipelines. The valve LDK-4 stands out due to its compact design and can handle differential pressure up to 100 mbar. We can produce this valve from any materials available on the market, depending on the application (temperature, medium, pressure).

With our three sided coated sealing gasket we can offer leakage rates of max. 0,05% of Kv 90°. To achieve a leakage rate of 0%, the valve will be equipped with a double jacketed gasket and charged with sealing air.

The mounting position of the valve standardly is provided with horizontal shaft, but upon request customized solutions are available.
