Abstract
The shut-off valve has a housing (2) provided with inlet and outlet ports (1) which also form valve seats. The sealing disc (3) is mounted on a C-shaped spring (7). The upper end of the spring (7) is fixed to the operating spindle (4). The lower end of the spring (7) has a semi-circular cut-out which fits round a conical projection (6) of the plug (9). The plug (9) is sealed by an O-ring (20) and is retained by a screw cap (13). By rotating the screw cap (13) the flexure of the spring (7) can be changed and in this way the pressure of the valve disc (3) against the seating face (8) can be adjusted.
