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.
