  2. Control valve - Wikipedia

    en.wikipedia.org/wiki/Control_valve

    A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller. [1] This enables the direct control of flow rate and the consequential control of process quantities such as pressure, temperature, and liquid level.

  3. Flow coefficient - Wikipedia

    en.wikipedia.org/wiki/Flow_coefficient

    The use of the flow coefficient offers a standard method of comparing valve capacities and sizing valves for specific applications that is widely accepted by industry. The general definition of the flow coefficient can be expanded into equations modeling the flow of liquids, gases and steam using the discharge coefficient.

  4. Automatic balancing valve - Wikipedia

    en.wikipedia.org/wiki/Automatic_balancing_valve

    Traditional control valves make it inevitable. As we size a control valve, the K v calculated almost certainly will not match the K v of the nearest appropriate valve. For example, a K v calculation of 4.5 m 3 /h would most likely lead to the selection of a valve with a K v = 6.3 m 3 /h. This means the valve is capable of delivering 40% more ...

  5. Valve actuator - Wikipedia

    en.wikipedia.org/wiki/Valve_actuator

    A linear actuator opens and closes valves that can be operated via linear force, the type sometimes called a "rising stem" valve. These types of valves include globe valves, rising stem ball valves, control valves and gate valves. [2] The two main types of linear actuators are diaphragm and piston.

  6. Flow control valve - Wikipedia

    en.wikipedia.org/wiki/Flow_control_valve

    Pneumatically-actuated globe valves and diaphragm valves are widely used for control purposes in many industries, although quarter-turn types such as (modified) ball and butterfly valves are also used. Control valves can also work with hydraulic actuators (also known as hydraulic pilots). These types of valves are also known as automatic ...

  7. Thermal expansion valve - Wikipedia

    en.wikipedia.org/wiki/Thermal_expansion_valve

    Thermal expansion valves are often referred to generically as "metering devices", although this may also refer to any other device that releases liquid refrigerant into the low-pressure section but does not react to temperature, such as a capillary tube or a pressure-controlled valve.
