The devices that can control the flow rate of fluid (liquid and gas) with an electronic signal are the electronic flow regulator and the electronic flow control valve. Digital water flow regulators are used to control liquid flow rates, and electronic air flow control valves are typically used to manage gas pressure by regulating the speed of air motors and cylinders. Users are provided with a digital reading of the liquid or gas flow rate by an electronic pneumatic proportional flow control valve in conjunction with a digital flow meter for closed-loop control, allowing users to anticipate the precise amount of flow. The digital flow control valve also has an internal flow controlling feature.
Flow control valves:
Electronic Flow control valve exist in a variety of forms, dimensions, and styles. To manage air movement, however, is their common purpose. The fundamental design of the flow control valve hydraulic systems (liquids under pressure) is the same. The basic water faucet seen in most houses is an example of a flow control valve.
Standard designs for flow control include globe valves and needle valves. Unidirectional flow control valves limit flow in one direction while flow adjustment valves allow unrestricted flow in the other. Additionally, pressure-compensated flow control valves are produced. These valves regulate the flow and keep it constant under a range of pressures. Despite being perfect for specific applications, these valves are more expensive and should only be used when necessary.
Hydraulic Flow Control Valves:
Additionally, an electric hydraulic flow control valve can be used with flow control valves (also known as hydraulic pilots). Automatic Control Valves is another name for these kinds of valves. In response to changes in flow or pressure, the hydraulic actuators will open or close the valve. Automatic Control Valves can be opened and closed by the fluid pressure alone and do not require an external power source. Pressure lowering valves, electronic flow control valve, back-pressure sustaining valves, altitude valves, and relief valves are some examples of automatic control valves.
The level of a tank is controlled by an altitude valve. When the tank reaches its maximum level, the altitude valve will close but remain open while the tank is not yet full. The valve operates automatically, thus its name, opening and closing without the need for an external power source (electrical, pneumatic, or human power).
High-Pressure Control Valves:
These have in-line hydraulic uses in mind. The electronic Flow Control valve controls flow in one direction while allowing full flow in the opposite direction, in contrast to the “Needle Valve,” which controls flow in both directions. The CS black oxide plated series Buna seals and the PS plated steel have high-temperature Viton seals, respectively. Use Angle high pressure flow control valve for fractional flow and high-pressure heavy-duty control valves for full or partial flow.
Digital Control Valve:
A multi-function control valve with electrical and hydraulic actuators is known as a digital flow control valve. An electronic batch controller can be utilized for local and remote-controlled batching operations. The valve also has a built-in flow regulating feature.
