Flow control valves are used to regulate the speed and pressure of the flow of liquids or gases through the pipeline. The proportional flow control valve is important to optimize system performance based on a flow switch or port with a variable flow area. In this article, we’re going to discuss the function of proportional control water flow valve and the different types and components. And how they work and some important considerations will also be the part of the article that can help you when choosing a flow control valve suitable for a specific application.
What is Control Valve:
The proportional flow control valve is utilized for the regularization of the flow of the fluids by changing its size or course as the signals of the regulator direct it. It aids in controlling the flow rate of the fluids directly. It also helps you regulate the other vital processes quantities like temperature, level, or flow of the liquids. The digital flow control valve is sometimes referred to as the final control element in the automatic control terminology.
The function of Hydraulic Flow Control Valves:
A proportional flow control valve aims to adjust the flow rate in a particular part of a hydraulic circuit. In hydraulic systems, they are used to control the flow rate in motors and cylinders to control the speed of those components. The solenoid valve flow control also controls the rate of energy transfer at a given pressure. It is based on the concepts of physics surrounding work, energy, and power:
The power transmission must equal the total work done. Since the speed of the actuator determines the rate of energy transfer, the speed is a function of the flow rate. The proportional flow control valve serves different purposes. It includes directing the power transmission system to the right place at the right time. Certain types of pressures and flow rates can be controlled with the help of a flow control solenoid valve, as they can stop fluid flow.
Advantages of using the Proportional Flow Control Valve:
Usually, the flow control needle valve is classified as the linear type or rotary, depending on the stem movement. It also depends on the types of services the flow controlling valve offers. Below are some of the advantages of using the proportional flow control valve.
- The flow control valve’s advantage is that it includes both the opening & closing features. Compared to the gate valves, they are faster when it comes to opening & closing time. Sometimes it also works as a stop check valve.
- It has a good Closing feature
- It can be used in either way in circuit
- It provides laminar flow, and hence the loss of pressure is minimum
Disadvantages:
- The closing and opening features are not very prompt.
- Assembling these valves and then erecting them, starting and maintaining them requires large space.
- Prone to leakage when the system operates at a temperature that periodically fluctuates.
- It creates vibration
