4.4.2.3 Function

Design

Gate valves with wedge discs 360 comprise body 100 with welded stellited seat rings
515, wedge discs 360 with stellited seating faces, bonnet 139 with gland packing 461
and yoke 166 with the actuating element.

Sealing

Shut-off is performed by two wedge discs 360 pressed against seat rings 515; they are
flexibly mounted in wedge/disc holder 367 and supported by replaceable thrust
inserts 553 via pins 563.
