Industrial Valves
(3,060 companies)
Valves are mechanical devices that control the flow and pressure of liquids, gases, and slurries within a system. They are also known as regulators and are used in a wide variety of applications. Valves vary greatly in size, design, function, and operation.

Primary Material of Construction
Air Valves
(793 companies)
Air valves allow metered fluid flow in one or both directions. They are used in pneumatic circuits to regulate the rate of activation or exhaust of cylinders and other pneumatic devices.
Ball Valves
(2,118 companies)
Ball valves are quarter-turn, straight-through valves that have a round closure element with matching rounded seats that permit uniform sealing stress. The valve gets its name from the ball that rotates to open and close the valve. Ball valves are used in situations where tight shut-off is required. They are wide duty valves, able to transfer gases, liquids and liquids with suspended solids (slurries).
Ball valves provide tight shut-off and characterizable control. They have high rangeability due to the design of the regulating element and few complications from side loads typical of butterfly or globe valves.
Hydraulic Valves
(686 companies)
Hydraulic valves contain and transfer the flow and pressure of hydraulic fluid in hydraulic power systems. They range from simple shutoff valves to precision control valves.
Butterfly Valves
(1,275 companies)
Butterfly valves control flow through a circular disc or vane by turning the valve's pivot axis at right angles to the direction of flow in the pipe. They are normally used as throttling valves to control flow.
Globe Valves
(799 companies)
Globe valves are linear motion valves with rounded bodies, from which their name is derived. They are widely used in industry to regulate fluid flow in both on/off and throttling service.
Gas Valves
(538 companies)
Gas valves are used to handle and control the flow of gaseous media such as liquefied petroleum and natural gas. They are made of metal or plastic and vary in terms of valve size, pressure rating, number of ports, and flow.
Gate Valves
(1,168 companies)
Gate valves and knife valves are linear motion valves in which a flat closure element slides into the media stream to shut off flow.
Check Valves
(1,956 companies)
Check valves are self-activating safety valves that permit gases and liquids to flow in only one direction, preventing process flow from reversing. They are classified as one-way directional valves.
Control Valves
(1,650 companies)
Control valves or proportional valves are power-operated devices used to modify fluid flow or pressure rate in a process system.
Valve Actuators
(917 companies)
Valve actuators mount on valves and, in response to a signal, move a valve to a desired position using an outside power source.
Diaphragm Valves
(425 companies)
Diaphragm valves close by means of a flexible diaphragm attached to a compressor.
Pressure Relief Valves
(1,009 companies)
Pressure relief valves are self-actuated safety valves designed to relieve excess pressure upstream from the line.
Tempering Valves and Thermally Actuated Valves
(102 companies)
Tempering valves and thermally actuated valves contain a thermal sensing component that opens or closes in response to temperature changes.
Plug Valves
(479 companies)
Quarter-turn plug valves use a cylindrical or tapered plug with a hole in the center to control straight through flow when in the open position.
