Flow control valves are also used to help prevent excessive flow rates. This is such a crucial purpose as it could prevent potential damage to equipment or cause system instability. Therefore, by limiting the fluid flow, the valves can ensure that systems are operating safely while preventing potential hazards or costly damages.

There are not only examples of techniques and mechanisms that flow control valves can use. Flow regulation can be achieved using disks, spools, or plates. The different mechanisms used depend on the specific design and application requirements.

As we have demonstrated above, flow control valves are essential devices in fluid systems that offer a way for operators to precisely control flow within a system. From irrigation systems to hydraulic systems, regulating flow rates can ensure system functionality, avoid damage to systems and ensure optimal performance.

While you may need a flow control valve to control the rate of fluid within a circuit you may be wondering how a flow control valve works and in what settings they’re most likely used. Here in this article, we will delve into the main purposes of flow control valves. You will learn about the different types of flow control valves that are available and how does flow control work across different settings. Read on to find out more.

ASME Section VIII, CE, CRN certified for unfired vessel protection.Used for many applications to protect or relieve pressure for Air / Gas or Steam.Set pressures: Air up to 300 PSI (20.7 Bar), Steam to 250 PSI (17.2 Bar).

You can find flow control valves are used extensively across a wide range of industrial settings. In particular, within the oil and gas industry. Flow control valves are used within this sector in pipelines, offshore platforms and refineries to regulate the flow of various fluids including crude oil and natural gas. They’re used within this setting to ensure safe and efficient processing, distribution and transportation of fluids and gasses.

While the concept of a flow control valve may sound confusing and complicated, in fact, they are pretty straightforward. A flow control valve adjusts and controls the flow of air or liquid within a system. Many people get confused between flow control valves, pressure controllers, and regulators. But while there are similarities, they do not work in the same way. For example, the use of a pressure regulator to control flow has the potential to damage components and can result in wasted energy.

Another example of where fluid control valves are used is within water management systems that control the flow of water in wastewater treatment plants, dams and irrigation networks. These valves play a crucial role in maintaining optimal water levels and ensuring effective water distribution and preventing flooding.

Another purpose of flow control valves is to balance flow distribution. This means that within systems that have multiple outlets or branches, valves can be used to ensure a precise balancing of fluid distribution. Adjusting each valve individually allows operators to ensure that each branch receives the flow rate required to ensure the overall performance and functionality of the system.

Therefore, flow control valves work by using mechanisms to control the flow rate. One of the most common flow control valve types is the needle valve This features a needle-like plunger that allows or restricts fluid flow by adjusting its position. This works as when the needle valve is partially closed the space through which the fluid travels is made smaller, which leads to a reduced flow rate. However, if the opening valve increases the size of the space then more fluid can pass through.

The ball valve is another type of flow control valve and it uses a spherical ball with a bore through the centre. Operators can control the flow rate using this kind of valve by rotating the ball. When the ball is rotated to line up with the pipeline fluid can be free-flowing. But if the rotating ball is perpendicular to the pipeline then the flow is restricted.

One of the main purposes of flow control valves is to allow users to regulate and adjust the flow rate of fluids within a specific system. They’re used by operators to increase or decrease the volume of fluid passing through a pipeline by manipulating the valve’s settings. This is particularly popular in scenarios where specific process requirements are needed.
