Automatic Control Valves

Automatic Flow Control Valve

A flow control valve regulates the flow or pressure of a fluid. Flow Control valves normally respond to signals generated by independent devices such as flow meters or temperature gauges. Control valves are normally fitted with actuators and positioners. Pneumatically-actuated globe 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 Control Valves. The hydraulic actuators will respond to changes of pressure or flow and will open/close the valve.

Automatic Control Valves do not require an external power source, meaning that the fluid pressure is enough for opening and closing the valve.

Control valves

...regulate the flow or pressure of a fluid. They normally respond to signals generated by independent devices such as flow meters or temperature gauges. They are fitted with actuators and positioners. Pneumatically-actuated globe valves are widely used for control purposes in many industries, although quarter-turn types such as (modified) ball and butterfly valves are also used.

They regulate the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways. They are technically pipe fittings, but are usually discussed as a separate category. In an open valve, fluid flows in a direction from higher pressure to lower pressure.

Pressure Control

Water Control valves can also work with hydraulic actuators (also known as hydraulic pilots). The hydraulic actuators will respond to changes of pressure or water flow and will open/close the valve. Flomatic® also carries actuated solenoid valves.

Flow Control

Idle Air Control

These are used in a variety of contexts, including industrial, military, commercial, residential, and transportation. The industries in which the majority of valves are used are oil and gas, power generation, mining, water reticulation, sewerage and chemical manufacturing.

Plumbing valves, such as taps for hot and cold tap water are the most noticeable types of valves. Other valves encountered on a daily basis include gas control on cookers, small valves fitted to washing machines and dishwashers, and safety devices fitted to hot water systems.

They may be operated manually, either by a hand wheel, lever or pedal. Valves may also be automatic, driven by changes in pressure, temperature, or flow. These changes may act upon a diaphragm or a piston which in turn activates the valve. Examples of this type of valve found commonly are safety valves fitted to hot water systems or boilers.

More complex control systems using valves requiring automatic control based on an external input (i.e., regulating flow through a pipe to a changing set point) require an actuator. An actuator will stroke the valve depending on its input and set-up, allowing the valve to be positioned accurately, and allowing control over a variety of requirements.
