A flow control valve is a useful tool that empowers the users to control the flow of the fluid by changing the size of the passage. The fluid passing in a system on a desired flow rate allows the user to conveniently adjust the other relevant process parameters such as the pressure, level of the fluid and temperature etc. A wide range of proportional flow control valves is available in the market that is designed to fulfil the needs of various systems. Understanding their working, and types is necessary to design an efficient fluid system.
Below we have listed four types of flow adjustment valves that are commonly used:
1. Directional Control Valves:
This type of proportional flow control valve is helpful in defining the direction of the fluid in a system. They are also referred to as switching valves because their main purpose is to direct the fluid in the right direction according to the need. An electronic flow control valve allows the user to choose an orifice for the flow of the fluid in a specific direction and a specified volume. The specified volume helps in controlling the speed of the cylinder or hydraulic motor. If you want to change the direction, flow or pressure of the fluid in the running state of the fluid system, then you will have to use a unique valve for each direction.
2. Proportional Flow Valve:
Proportional flow control valves help in achieving the infinite positions of the spool and allow the users to have strong control over the fluid flow. This ability to provide variable spool position allows designing with metering notches to achieve the expected flow or speed control without requiring separate direction control valves. Another great benefit is that if the circuit requires to have various speeds then it can be achieved easily by changing the input electronic signal.
This type of flow rate control valve allows the user to achieve the desired acceleration and deacceleration for the safe operations of a system. Meanwhile, it allows a machine to perform a number of cycles, at great speed. The precise regulated acceleration and deceleration provide improved cycle time and lowers operational costs.
3. Pressure Relief Valve:
This type of flow control valve is used to limit the pressure in a system by releasing excess pressure in the atmosphere. These proportional flow control valves are easily controlled with the help of electronic signals and are designed to operate at different pressure and temperature ranges.
4. Pressure Reducing Valve:
This type of proportional control valve helps in keeping the pressure equal to the allowable limit of a system. So that it can not damage the plumbing system or your appliances.
Final Words
Today, proportional flow control valves are widely used in various hydraulic and other fluid systems in accordance with electric signals. They are commonly used to solve flow and pressure issues. In a fluid system, a fluid control valve serves to enhance the accuracy and efficiency of the system while reducing the number of components and keeping the system safe.
