  • Solenoid Valves-Image
    Solenoid Valves - (999 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...

  • Gate Valves-Image
    Gate Valves - (1172 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...

  • Check Valves-Image
    Check Valves - (1952 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...

    Ball Valves - (2080 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 - (1006 companies)
    Pressure relief valves are self-actuated safety valves designed to relieve excess pressure upstream from the line. Pressure Relief Valves Information. Pressure relief valves are designed to provide protection from over-pressure in steam, gas, air...

    Needle Valves - (562 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...

...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...
