When working with different types of fluids, measuring and controlling how they flow important. To do this, the flow controller and valves are needed because they produce accurate reports and results. Since there are many types of fluids, flow valves also come in many types. These flow valves are categorized into complex and simple types. The simplicity and complexity of the application will determine the type of valve to be used.
Many of the complex valves can adjust automatically. This will depend on the pressure and the fluid temperature that flows through the pipeline or channel. Flow valves are also designed differently, but their main purpose is to sense and pick up signals from the flow of the fluids that react to them. Temperature gauges are also vital devices for measuring and controlling the flow of fluids in a pipe or an enclosed channel. They work almost the same way as flow meters.
In this article, we focus on the various types of flow control valves used to check and regulate the flow of fluids. In this case, fluids stand for both gases and liquids.
What is a flow controller used for?
Flow control valves vary in their make and design depending on what they are created for in a hydraulic system. However, some flow control valves are commonly used in industries. One of them is called the motor speed regulator. At any given point, a flow controller can affect any fluid transfer rate within a system. This is an important feature when trying to regulate fluid flow. By influencing the rate of energy transfer, these controllers also regulate the speed of the motors.
In reducing or increasing the fluid pressure in a system, users get several benefits. One of these benefits includes depressurizing a hose in system operators. Flow control valves are also used for domestic use in our homes. For example, in the lawn watering system, pressure can increase or decrease depending on various factors. Showers and faucets also use control valves to regulate liquid flow. Many of the flow control valves are designed to resist clogs, which gives them a long life. Let’s now look at the commonly used flow control valves.
Commonly Used Flow Control Valves
1. Globe valves
This type of flow sensor is used in many sectors and works in linear motion. They are meant to either start or stop the flow of fluids running through pipes. It has a plug that initiates closure inside it. The plug consists of a lowered flat bottom of convex placed horizontally in the middle of the valve. As the user allows liquid to flow through the pipe by opening the valve, the plug rises. Unlike other fluid control valves, a globe valve produces slightly higher pressure drops. However, applications that don’t require pressure drops also use this type of control valve since their main purpose is to regulate flow.
2. Pinch Valves
A pinch flow sensor comes in handy when trying to control slurry or suspended liquids. They are also cost-effective due to their low maintenance cost. Users in this type of control valve turn off the flow by pinching rubber-like tubes. The valve body is the actuator making it unnecessary to have pneumatic, hydraulic, or electric operators. This is another aspect of a pinch valve that makes it cost-effective.
Flow control valves come in many types, but they are mainly made to regulate fluid flow in pipes. This makes them important in any hydraulic system. These two are just a few of the control valves used in different industries.
