Hundreds or perhaps thousands of control loops work together in process facilities to create a marketable product. A control valve modifies the position of the valve plug or disc, which is managed by a lever to control the flow of fluid.
Electronic flow Control valves are employed to keep a process variable as close as feasible to the intended set point. Controller set points for flow rate, pressure, and temperature are typical. Additionally, product properties like density, concentration, liquid level, and others can be controlled by means of control valves.
What are Control Valves?
Pressure and flow rate can be controlled and regulated via airflow control valves. They can complete the task automatically, freeing you from having to monitor the system constantly.
You can select the ideal control valve based on the desired pressure. It’s fascinating to learn that because process control valves function within their system, control valves are also referred to as the ultimate control element in automatic control language.
Parts of Electronic Flow Control Valve:
The following parts make up a control valve installation:
- A valve body
- A controller
- A positioner
The body comes with trim pieces and a bonnet assembly. Its construction enables fluid flow, provides pipe-connecting ends, can bear fluid static pressure and differential pressure, and can support seating surfaces and a valve closure part.
Electric, hydraulic, or electrically powered actuators are tools that supply the force needed to open and close a valve. Positioners monitor and regulate true actuator movement to keep the set point at the intended value.
Accessories include things like limit switches, pressure regulators, hand wheels, position indicators, and electrical sensors.
Types of Flow Control Valves:
While talking about the electronic flow control valves you can easily find the different types of it that are below:
- Valves for High-Pressure Control
- Ball Valves with V-ports
- Distinctive Ball Valves
- Gate valves and butterfly valves
Advantages of Flow Control Valves:
A high-quality control valve offers several wonderful qualities, including high performance and simple maintenance. The capacity to tolerate a variety of situations and durability are two additional advantages of using such units.
Control valves assist reduce process and product variability in addition to saving you money by removing extra expenses.
Based on the established standards, it also adds safety to each and every process carried out by the connected components.
Now that you are fully informed about airflow control valves, you may now be familiar with different types and uses of flow control valves. Additionally, feel free to use it at your home, firm, or any location where you want to install it.
Applications of Control Valves:
In the oil and gas sector, digital flow control valves are used to manage the flow of liquids and gases. Different industries use it in several ways.
First, all you need is to know how to use it. Oil and gas companies utilize high-pressure electronic flow control valves in the following applications:
- On a liquid dump valve or a separator.
- Back Pressure from gases can occur in any production vessel.
- Reduction in compressor pressure.
