Abstract

The valve body is in two parts, assembled together using spacers and bolts. The slide (3) has pins (8) moving in guide slots (9, 10) and has one end being attached to a power cylinder (6) by a link (7). This cylinder has a bellows type seal. To close the valve the cylinder moves the slide over the outlet, a sealing ring (4) of indium being positioned over two sets of knife edges (5), in the form of annular rings. Small hydraulic pistons (11, 12) fitted with sealing bellows, move the slide onto the knife edges. To break the vacuum similar pistons (13) on the other side push the slide upwards after the pistons (11, 12) have been retracted.
