Abstract: The sliding parts, the guides and interlocking portions of the interlocking guides and slides of a slide valve are all disposed away from a flow path through the valve. Additionally, the portions of the interlocking guide on the slide or disc of the valve that interlock with the guide on an orifice plate are connected to the slide or disc by welds instead of bolts, greatly increasing durability.

Accordingly, all critical sliding surfaces are not exposed to the flow path and are greatly increased in durability.

Abstract: A dust and abrasive materials gate valve with an angled valve seat and pivotably mounted valve gate allows for a broad seal area around the periphery of the valve seat, which may be closed tightly by a wedging action due to increasing force applied by the valve actuator. The valve seal is thus not formed along a single, linear surface as in traditional gate valves and the force applied by the valve gate to the seat facilitates closing even if there is wear along the sealing surfaces. Due to the relatively large open area around the periphery of the valve gate just before closing or immediately upon opening, the velocity of particles in pressurized systems is reduced and erosion reduced accordingly.
