  • Solenoid Valves-Image
    Solenoid Valves - (993 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...

  • Butterfly Valves-Image
    Butterfly Valves - (1244 companies)
    Image Credit: Direct Industry. Solenoid operated valves use hydraulic fluid for automatic control of valve opening or closing. Manual valves can also be used, with a solenoid valve, for controlling the hydraulic fluid; thus providing semi-automatic...

  • Check Valves-Image
    Check Valves - (1944 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...

  • Gate Valves-Image
    Gate Valves - (1170 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...

    Ball Valves - (2071 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...

    Pressure Relief Valves - (995 companies)
    ...valves. With many of these designs, a helical or hydraulic pressure spring is used to maintain constant force acting on the backside of the valve disk or diaphragm, causing the valve to be normally closed. When the force exerted by the process...

    Needle Valves - (565 companies)
    Needle valves are small valves used for flow control in liquid or gas services. The fine threading of the stem and the large seat area allow for precise resistance to flow. Needle valves have a slender, tapered point at the end of the valve stem...

    Industrial Valves - (3256 companies)
    ...is for hand-operated, rapid opening valves, and control valves that operate by hydraulic or pneumatic cylinders. Rotary stem- This is a commonly used model in ball, plug, and butterfly valves. A quarter-turn motion of the stem opens or closes the valve. Stem...

...such as a valve with an unusual spool configuration, using a component-builder utility. These symbols go beyond 2D schematics because they are linked to mathematics that describe operating characteristics used in simulations. New symbols can be dragged into a custom library for reuse and to share...
