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. As the slide or disc moves in and out to control the flow rate precisely, the guides of the slide or disc move with it. Because the sliding surfaces of the orifice plate and the slide or disc are outside of the flow path, they are consequently not subjected to erosion from the flow through the valve. Accordingly, all critical sliding surfaces are not exposed to the flow path and are greatly increased in durability.

Abstract

A valve device is provided for controlling air flow. The valve device includes a plug closure member having an interior chamber and a stop device positioned within the interior chamber of the plug closure member. The valve device further includes a check valve having a plate positioned adjacent an inlet opening of the plug closure member and an alignment device attached to the plate and received within a stop opening of the stop device. The check valve is movable between a closed position in which the plate limits passage of a lift air through the interior chamber and an open position in which the plate allows passage of the lift air through the interior chamber. The stop device engages the check valve in the open position.

Abstract

Stems used to connect an actuator to a gate are often match drilled. However, match drilled stems bear both a thrust load and a torque load. Provided herein is a valve stem coupling assembly that separates a unitary valve stem into two separate but coupled sections to isolate the thrust load from the torque load. In particular, the assembly comprises a first stem, second stem, a coupler comprising a first stem receiving channel, a second stem receiving channel aligned with the first stem receiving channel, and a plurality of pin receiving channels. The coupler end of the first stem comprises a forked receiving portion configured to receive the first pin at a variety of positions along the forked receiving portion.
