Advantages and purpose 1. Resilient seated gate valves are the perfect solution as a closing device in pipeline systems. 2. Because of the straight bore all impurities can pass through the valve without doing any harm, Combined with the full bore it will prevent pressure loss caused by turbulence. 3. The high quality rubber on the wedges is characterized by low deformation and high impact resistance which combined with the large valve seat area gives optimum tightness. 4. The test has proved that impurities up to 5mm can be handled by a DN**0 valve without any problems. The same test has also proved that the unique rubber quality instantly returns to the original shape when the valve is opened again. Be suitable in applications with water supply, sewage treatment and neutral liquids in the mining industry, enterprises and high buildings.
