Ventilation Valves (LDK)
The design of ventilation valves is adapted to the requirements of ventilation systems. Depending on the application they are screwed or clamped between flanges in pipelines. While the lengths of flanged valves is variable, the lengths of the clamped versions are limited by the material cast due to the material thickness. With the flanged version we can achieve an improved impermeability by customized deign. An advantage of the clamped valves is their lightweight construction.
The throttle valve type LDK-1 is a lightweight valve in the fields of control technology and shut-off technology. They are clamped between flanges according to DIN 24154 T2R2/R4 in pipelines. The valve LDK-1 stands out due to its compact and lightweight design. It can handle differential pressure up to 100 mbar.
According to your application (temperature and medium), we produce the LDK-1 in any material available on the market. The standard mounting position of the valve is provided with horizontal shaft, but customized solutions are available on request.

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.
