Slide gate valves

These versatile valves are designed for a wide range of gravity flow applications. All share the same one-piece cast housings and heavy duty components that ensure reliable low maintenance operation for many years. Slides are sealed internally by a replaceable polyurethane or steel wiper ring. The end of the slide plate is sealed with an adjustable packing gland. Between the two seals is a wiper blade that ensures long seal life. Both the inlet and outlet flanges are drilled and tapped with identical patterns to simplify installation. A range of actuators is available to accommodate most applications.
