Low-Maintenance, Self-Cleaning Slide Gate Valve

Low-Maintenance, Self-Cleaning Slide Gate Valve

Large clearances avoid jamming and material flow is unimpeded

Aerodyne’s StopTight valve is available for manual or pneumatic operation, in numerous sizes, and in carbon or stainless steel versions.

The AERODYNE StopTight® slide gate material handling valve is a “dust tight” component for flow control in dry bulk material handling. The slide-gate drive action eliminates the need for racks, pinions, cams, or other internal mechanisms that tend to interfere with valve operation. Large clearances avoid jamming during operation and material flow is unimpeded by any restriction or obstruction when the Slide Gate Valve is open. The moving parts are self-cleaning.

The low-maintenance valve is available for either manual or pneumatic operation. In the manual version, minimal turning of the handwheel compresses or relaxes the leaf spring assembly allowing the slide plate to rise or drop from the inlet collar. The valve is then opened or closed by pulling or pushing on the handwheel.

The pneumatic valve operates by an air cylinder closing the valve by forcing the leaf spring assembly to compress against internal stoppers. The slide plate rises to seal against the inlet collar. As the air cylinder withdraws, the leaf springs relax, allowing the slide plate to drop and slide clear of the inlet.

The unit is offered in a wide range of sizes, in carbon or stainless steel versions, and is well suited to high-temperature and severe-duty applications.
