Flange-Throttle Valves (FLD)

The FLD is a flange valve made for heavy duty use. It works reliably, even with dust-laden mediums and at high frequency of operation. The dismantling of the pipeline is, as opposed to ring throttle valves, on one side of the valve possible without it to be affected.

FLD-16

The flange throttle valve type FLD-16 with flanges drilled according to DIN 1092-1 PN-6, PN-10 or PN-16, is installed in pipelines. This valve is characterized by its robust and heavy construction and works reliably even in difficult environments.

Depending on the application (temperature, medium, pressure), we can customize this valve of almost any material 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 even at high pressure. To achieve a leakage rate of 0%, the valve will be charged with sealing air.
