ABSTRACT OF THE DISCLOSURE In order to resist alteration of the spring forces utilized for applying seal pressure between the valve bodies in sliding gate valves for molten metal pouring, particularly those of the manually operated type, the valve support plate and the mounting plate are arranged to form a narrow slot that receives the valve actuator and presents insufficient clearance to permit excessive relative displacement between the valve members. The valve further incorporates releasable attachments, two of which serve as hinge connections for the support plate while the other serves as a latching member. Each of the attachments comprise clevis-mounted eyebolts in which the clevises have predetermined dimensions to establish a fixed, pre-set distance between the plates upon reassembly of the valve after opening and thus insure repeatability of the spatial relationships between the valve bodies and, concomitant- ly, of the seal pressure between the members.
