Butterfly valves are a family of quarter-turn rotational motion valves that are used in pipelines to shut-off flow. It is often said that butterfly valves can be used to regulate the flow. However, we do not recommend doing this, as it can damage the valve disk and have a negative effect on the sealing properties. They are used in a wide variety of process media and industries especially in water supply, collection, and distribution, as well as pumping stations, and have a broad range of use cases especially in flow isolation. A couple of their key advantages over other valve families are their simple construction and compactness, resulting in the end products being of lighter weights and lower cost and with smaller installation footprints and faster actuation speeds.

SN Offer a wide range of globe valves in a variety of sizes, pressure ratings and materials.

Globe valves are linear motion valves with rounded bodies, from which their name is derived. During the opening of the Globe Valve the fluid flows through the space between the Edge of the Disc & the seat. Globe valves are linear motion valves with rounded bodies from which their name is derived. During the opening of the Globe Valve the fluid flows through the space between the Edge of the Disc & the seat. These kind of valves are generally used in industry as fully open or fully closed valve, but they may be used for throttling as long as fine adjustments are not required. Globe valve are ideal choice to control the gases such as steam. A user can use it for throttling with little modification in plug & seat.

SN have a wide range of GATE VALVES in variety of types, sizes, pressure ratings and materials, with wafer type, screwed, welded or flanged connections. SN Manufacture Gate valves in every size ranging from the smallest to the largest size Gate Valve name is derived from the operation of the Gate valve.

The Valve Acts like a Gate to stop or allow the flow through the valve. The valve can be opened by lifting the wedge out of the path of the flow Gate valves are actually designed for closing & opening full , so they are not suitable for the Throttling purpose. When the Gate valve is fully open, there is no Obstruction in the Flow path, resulting in very low pressure drop, & they are often suitable for the Hot Tapping & Pigging.

Gate Valves are actually designed for use with the flow of liquids and Gases but there are variation to cope with the specific requirements.
