'''Slide Gate''' is a crest gate which has high frictional resistance to opening because it slides on its bearings in opening and closing.


Slide gate operators are commonly installed at the end of the gate in the closed position but can also be installed by the end of the gate in the open position. In America the most common form of automation is a chain attached across the gate near the bottom and passing through the operator, which shuttles it back and forth. In the end of the gate or open position you do not see the chain or any operating equipment near the gate. In Europe a metal or plastic rack is attached to the gate with a gear fitted to the operator. The American method is more flexible and allows for greater movement in the gates, the European method makes for a quieter and more secure system. Sliding gates are often large, heavy and therefore more hazardous than swing gates they can however be equipped with appropriate safety devices making them some of the safest gate systems available.

'''Slide Gate ''' is designed for shut off and throttling in difficult abrasive and/or high solids slurry service. The standard round port configuration is used for on/ off service and the optional diamond port configuration is used for throttling. Available with a handwheel or automated, and it  has the unique ability to operate in a static column of solid particles and powders. The opening in the slide gate merely moves a disc of material laterally then returns it when the slide gate is reversed. Consult factory for shut off capability with standard and optional seats.
 
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]] are available to accommodate most applications.
 
 
==Uses==
Slide gate are used especially for transporting the powder, pellet matter and other bulk material in petrochemical, chemical, food and medicine industry etc. They are mainly used in cutting or transport.
