<p>Valve wedge (11) for a slide valve (1) comprising a rough cast metal wedge core (13) encapsulated in, i.e. coated with, a soft seal encapsulation (50) and having two guide members (20) projecting transversely in opposite directions. Each of the guide members (20) comprises a sideways projecting rib (17) of said rough cast wedge core and a prefabricated wear and corrosion-resistant slide shoe arranged thereon, each rib (17) comprises laterally opposite lateral surfaces (19) and each shoe comprises two opposite lateral walls (22) with inner surfaces (27). Each shoe (23) is fixedly vulcanized to the respective one of the ribs (17) by means of soft seal encapsulation (50) present between the rough cast wedge core (13) and the shoe (23). The outer lateral surfaces of the ribs are finished surfaces (19) and that the opposite inner surfaces (27) of each of the slide shoes (23) is laterally rigidly supported by the corresponding outer lateral surfaces (19) of the respective one of said ribs (17) so that each rib laterally rigidly supports the respective one of said slide shoes (23).</p> |
