Industrial Valves #4968776

Plug valves are quarter-turn rotational motion valves that use a tapered plug to stop or start flow. They typically have a rectangular port shape and come in either non-lubricated (also called self-lubricated) or lubricated designs. Plug valves can be used in many types of fluid services and perform well in slurry applications.

Check valves are self-operated valves that open with forward flow and close with reverse flow. The pressure of the fluid passing through a system opens the valve, while any reversal of flow will close the valve. Exact operation will vary depending on the type of check valve mechanism. Common check valve types include swing, tilting-disk, piston, ball and butterfly valves.

Butterfly valves are quarter-turn rotational motion valves that use a round disk control element to stop or start flow. Common butterfly valve body types include wafer, lug and flanged-end designs.

Globe valves are a linear motion valve primarily designed to stop, start and regulate flow. The disk of a globe valve can be totally removed from the flowpath, or can completely close the flowpath. Conventional globe valves may be used for isolation and pressure-reducing services, and come in three primary body designs: Tee Pattern or Z-body, Wye Pattern or Y-body, and Angle Pattern.

Gate valves are primarily designed to start or stop flow. In service, these valves are generally either fully open or fully closed. They are available with different disks or wedges, including: solid wedges, flexible wedges and split wedges (self-adjusting and self-aligning to both seats sides). These valves are often used when a straight-line flow of fluid and minimum restriction is desired. Because of their ability to cut through liquids, gate valves are often used in the oil industry.

An angle valve is essentially a globe valve. It is a linear motion valve designed primarily to stop, start and regulate pressure. The disk of a globe valve can be totally removed from the flow pathor it can completely close the flow path. The angle valve provides for a 90-degree change in flow direction, eliminating the use of extra fittings and elbows.
