Our sampling valves are made of stainless steel AISI 316L (EN1.4404), AISI 304L (EN 1.4307) or Duplex 2205 (EN 1.4462). The metal gasket-equipped ball is chrome-plated, with stellite seats. On the edge of the seal is a scraper groove that cleans the surface of the ball as it opens and closes. Its structure is designed specifically for fibrous material. PTFE (Teflon) sealed ball valves are made with a solid ball of compatible material.
The flange for attachment to the connecting pipe is machined to match the inner radius of the pipe, allowing the medium to flow as smoothly as possible from the connecting pipe to the valve. Standard valve sizes DN15 – DN200 according to the manufacturing specifications.
