A discharge valve (20) comprising a valve housing (21) which can be functionally connected to a process element (10) having a pressurized interior space. The valve housing (21) comprises a flow channel (22) having a longitudinal centre axis (A) and being in working cooperation with a valve member (23). The flow channel (22) is arranged to be in fluid communication with the pressurized interior space in the process element (10) after the discharge valve (20) has been connected to the process element (10). The valve member (23) is displaceable between an open position and a closed position in a displacement direction (B) whereby the discharge valve (20) can be opened and closed. The flow channel (22) comprises a detachable inner lining (25) having an envelope wall (26), wherein the detachable inner lining (25) comprises an aperture (30) extending through the envelope wall (26) and through which the valve member (23) is adapted to run when being displaced between the opened position and the closed position. |
