The ROETELMA valve designated DN 20 corresponds to a nominal diameter of 20mm and features a 3/4 BSP threaded connection. It is designed for a maximum pressure of PN400, which corresponds to an operating pressure of approximately 400 bar. The construction combines steel (St) for robustness and POM-N (Polyoxymethylene-Nitrile) for specific sealing and wear properties, ensuring good chemical resistance and low friction. This material is often found in the valve seat or sliding elements. This valve is a reliable solution for applications in hydraulics or pneumatics where high pressures and chemical resistance are required. It is suitable for use in industrial plants and mechanical engineering. Secure this proven component for your fluid technology projects.
