sliding gate valves are linear motion gate valves. The gate valves are the most used valves to control the flow of fluids and gases in pipelines. The gate valves come in different types. Sometimes valves are needed to control the flow of powdered material as well. The sliding gate valves pneumatic is a type of gate valve that has airtight opening and closure. The gate is made up of ductile iron or mild carbon steel depending on the application need. The sliding gate valves manufacturers produce the valves in different grades of materials such as ferritic, austenitic, duplex and alloy steel materials. The slide gate has a rectangular slide plate or a stainless steel plate to open or shut the dry material flow through the valve.

Pneumatic Sliding Gate Valve
The compression loaded polymer plates on two sides accommodate the slide plate. This type of gate valve can self clean due to the opening and shutting operation. This prevents packing of material inside the valve and clocking it. The slide gate valves suppliers produce the valves in different dimensions according to the DN and other international standards. There are valves ranging from 2 inches to 24 inches and pressure capacities ranging from PN10 through PN16 in general. But based on the customer requirements, larger diameter valves such as sliding gate valve 90mm can be produced. Slide gates are preferred where knife gates cannot perform sufficiently to control the flow of powdered material. The applications are mostly in food processing and pharmaceutical industries.
