The valve type RA has a flange connection based on DIN 24193 T3, but other patterns of drilling are feasible on request.

Depending on the application (temperature, medium, pressure), we can customize this valve of any steel available on the market. With our three sided coated sealing gasket we can offer an impermeability of at least 99,95% as compared to the fully opened disc. To achieve a leakage rate of 0%, the valve will be charged with sealing air.

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