6 Types of Flow Controller Devices with Benefits

Having a controlled and stable flow rate of liquids flowing inside the pipes is vital for accurate use of water and other liquids. The purpose is generally served by the flow control valves that are available in different types. Their work varies from simple to complicated, but all are beneficial to use. They work automatically to alter the flow and pressure of liquids as per the signals commanded by the flow meters. So, here is a guide to know the best 6 flow controlling devices with their benefits.

Gate Valves

The most commonly used flow controllers are gate valves that are used in applications with straight-line for liquid flowing. These devices are easy to operate by using a stem to stop and resume the flow.

Benefits

These valves cause low obstruction in the liquid flow consequently, the chance for loss of pressure is minimal.|
These valves have a convenient and faster opening and closing mechanism, so they have the best performance.
The versatility of these valves lets them control the flow of fluids like oil, steams, and viscous liquids.

Pinch valves

These flow controllers contain rubber tubes that become pinched to discontinue the flow of liquids. Working with these devices is ideal in the case of liquids having suspended solids such as soil, wastewater particles, and biological solids. These valves can tightly close the flow of liquids to prevent unnecessary flow.

Benefits

These are inexpensive flow-controlling devices.
Pinch valves require less maintenance as compared to others.
These valves have simple installation and have clean working due to low airborne contaminants.

Globe valves

Using these flow control valves is useful to stop, resume, and regulate the flow of liquids. As the name suggests, these valves contain a flow-stopping disk that is made in the globe shape. These valves are ideally used for on and off-throttling applications. The disk inside this valve can work to close the flow by obstructing the path. As the disk is removed from the flow path, the flow of liquid would resume. However, globe valves are suitable for flow controlling where pressure drop in a flow is not a primary controlling factor.

Benefits

These controllers have good shut-off capacity than other valves.
This valve has unique working capabilities as they are available in angle patterns, tee, and wye.
These valves provide tight closing to prevent even the minimal leakage of water and other liquids.

Needle valves

Among the range of flow controllers, these devices are used to restrict the flow of liquids in small pipes. These valves contain an orifice that serves as the seat for the cone-shaped and tipped rod. These valves are used in various industries since they allow several measuring instruments to install and removed safely.

Benefits

These valves are considered best at accurate flow control.
The small size of these valves enables easy installation.
These valves have easy shut-off capabilities.
They use perfectly for throttling purposes.

Diaphragm valves

The working principle of these flow control valves contains a flexible disk that works to contact the seat of the valve body. It works perfectly to seal the flow of liquids and is easy to open and close to regulate the flow. The elastomeric diaphragm attaches to the compressor that separates the flow stream.

Benefits

These valves are ideal for regulating unnecessary flow with dirty fluids.
They are extremely clean and feature tight leak-proof sealing.
The ease of use and maintenance makes these valves the primary choice among various industries.

Ball valves

These valves use in household water-flowing pipelines. They put into the pipe with a revolving ball to control the flow. They operate by hand usually.

Benefits

Easy operation
Better leak-proof technology
Light in weight and easy to maintain
Flexible in choosing due to availability in several sizes and shapes

Conclusion

These are the top-rated 6 flow control valves that are used primarily for preventing the unnecessary flow of liquids. They are available in the market to purchase. It advises to operate them after a thorough understanding of use.
