  • Valve, especially for fluid handling bodies with microflowchannels
    Patent number: 5593130
    Abstract: A valve of the membrane valve type comprises a valve body with two fluid flow channels (5, 5') separated by a land portion which forms a valve seat (6) having a sealing surface for co-operation with a flexible membrane (7) mounted over a duct (8) which opens in front of the valve seat and is arranged for fluid pressure actuation of the membrane between a closing position, where the membrane (7) sealingly contacts the valve seat (6), and an opening position where there is a flow channel communicating space ( 11) between the valve seat (6) and the membrane (7).
