Valve Types

    ball-valve

    valves are used to control liquids and gases movements and to adjust its flow and pressure . It has many types due its function

    1. Ball #valve , for on/off control without pressure drop, and ideal for quick shut-off, since a 90° turn offers complete shut-off angle, compared to multiple turns required on most manual valves.

    2. Butterfly valve, for flow regulation in large pipe diameters.

    3. Clapper valve, Used in appliances like the Siamese fire appliance to allow only 1 hose to connected instead of two (the clapper valve blocks the other side from leaking out.

    4. Check valve or non-return valve, allows the fluid to pass in one direction only.

    5. Ceramic #Disc valve, used mainly in high duty cycle applications or on abrasive fluids. Ceramic disc can also provide Class IV seat leakage

    6. Choke valve, a valve that raises or lowers a solid cylinder which is placed around or inside another cylinder which has holes or slots. Used for high pressure drops found in oil and gas wellheads.

    7. Gate valve, mainly for on/off control, with low pressure drop.

    8. Globe valve, good for regulating flow.

    9. Diaphragm valve, which controls flow by a movement of a diaphragm. Upstream pressure, downstream pressure, or an external source (e.g., pneumatic, hydraulic, etc.) can be used to change the position of the diaphragm.
