The primary function of a flow control valve is to control the flow rate and manage the pressure efficiently. They can be used to perform various tasks from switching the path on and off for the fluid to pass so that the user can have strong control over the flow rate and pressure. Today, numerous categories of proportional solenoid valves are available in the market. To get optimal performance, it’s crucial to choose the right product according to the requirement of the system.
Proportional flow control valves are designed to open and close the passage of the fluid when they received a signal from the controller. They manage the flow of the air in pneumatic systems. These valves are extremely used at the industrial level because of their benefits and robustness.
Here we have listed 4 common types of pneumatic flow control valves:
Direction Control Valves:
All fluid power systems require proportional solenoid valves to direct and regulate fluid flow in the right direction. These valves are commonly found in almost all pneumatic systems. In pneumatic systems, the compressed air is regulated and controlled to control the movement of the air actuators and air motors. Flow rate and pressure are necessary to be maintained for obtaining the expected speed of actuators and force. This is achieved with the help of a flow control valve.
The main function of a direction control valve is to control the flow rate and the direction of the fluid in the circuit. A solenoid operated valve is used to start, stop and regulate the airflow and to properly distribute the air in the lines for performing the work efficiently.
These flow valves enable the flow of the fluid in only one direction and the other direction remains blocked all the time. Further, these proportional solenoid valves are specifically designed to provide only one direction for the passing fluid. Because of this, they are also known as one-way valves.
Let’s take a look at a few commonly used Non-return valves:
- Shuttle Valve.
- Check Valve.
- Quick Exhaust Valve.
Pressure Reducing Valve:
As the names show these solenoid proportional valves are used to control the flow of the fluid or gases. This type of valve is used to regulate the precise flow rate of the air. The control element limits the passing air to maintain the required flow rate.
In pneumatic systems, pressure control valves are installed to control the pressure of the air because the pressure of the compressed air can rise at any time. But the availability of a proportional solenoid valve ensures the safe working of the system by keeping the pressure low to make a process happen precisely. A pressure-reducing valve is an integral component of the pneumatic system. Usually, they are open two ways valves and are closed when they are subjected to pressure. They are divided into subcategories as direct-acting and pilot-operated valves.
Pneumatic control valves are commonly used in many systems, machines and equipment to perform tasks by regulating the precise flow and pressure of the air. Above we have discussed some types of pneumatic valves.
