Valve, especially return valve

摘要

The valve seating (6) matches the valve's main body (5) on at least one sealing edge (9). At least two sealing edges are arranged in fluid series in relation to the through-flow of the valve (1). At least one sealing lip (8) is integrated in the valve body and has its own seating. The valve body is pre-tensioned into its closed position by means of a restoring spring (7). The valve body is movably guided in a housing (4).
