  • Ball Valves-Image
    Ball Valves - (2117 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...
  • Hydraulic Valves-Image
    Hydraulic Valves - (684 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. In their unpowered state, hydraulic valves can be normally open (open...
  • Gate Valves-Image
    Gate Valves - (1166 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. Gate valves (also known as knife valves or slide valves) are linear motion valves in which a flat closure element...
  • Solenoid Valves-Image
    Solenoid Valves - (1023 companies)
    Solenoid valves are devices that use a solenoid to control valve activation. They are considered electromechanical control devices used to control liquid or gas flow. An electrical current runs through a coil to control the valve by moving a plunger...
  • Check Valves-Image
    Check Valves - (1954 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. Check valves are self-activating safety valves...
  •  
    Butterfly Valves - (1272 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. Butterfly valves are quarter-turn...
  •  
    Gas Valves - (537 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. Gas valves are flow...
  •  
    Control Valves - (1648 companies)
    Control valves or proportional valves are power-operated devices used to modify fluid flow or pressure rate in a process system. Control valves are power-operated devices used to automatically modify fluid flow or rate pressure in a process system...
  •  
    Globe Valves - (796 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. As their name suggests, globe valves are linear motion valves...
  •  
    Pressure Relief Valves - (1008 companies)
    Pressure relief valves are self-actuated safety valves designed to relieve excess pressure upstream from the line. Pressure relief valves are designed to provide protection from over-pressure in steam, gas, air, and liquid lines. Relief valves...
