This valve is designed to be installed to the end flange of piping or between flanges that are drilled in accordance with DIN EN 1092-1 or ANSI Class 150 and working pressure up to 16 bars (ANSI Class 300 and higher as per request). In the open position, the disc will be in the middle, allowing the best flow condition with minimum pressure loss. The seat is in a U-shape rubber liner that covers the inside of the body, is replaceable, and provides reliable sealing from both directions.
Note: There is no need for sealing washers in these types of valves, sealing washers disrupt valve performance.
