What Is the Difference Between High and Low-pressure Ball Valves?

High-pressure ball valves and low-pressure ball valves are the two kinds of ball valves available for controlling the fluid flow mechanism. 

It is important to note that the differences between low-pressure and high-pressure ball valves are significant. When using a valve for low-pressure applications, it is preferable to utilise a low-pressure valve. A high-pressure ball valve is designed to withstand more significant working pressures while allowing a continuous fluid stream to flow through the valve. They are also more durable due to their structure and high-quality manufacturing.

Difference between ball valves with high and low pressures:

Applications for Low-pressure Ball Valves

Low-pressure ball valves are found in household equipment, including toilets and sinks. Their operation does not generate significant pressure since the water flow is delivered by gravity. Generally speaking, they are more prevalent in businesses where long-term dependability is essential. They are capable of withstanding pressures of up to 200 psi. A ball valve may regulate high-pressure fluid flow under certain conditions.

Applications for High-pressure Ball Valves

Generally, high-pressure ball valves are used in applications that need consistent shut-off power. They are widely used in the oil and gas sector for various purposes. They are often utilised as backpressure and suction controls in pipelines, respectively and have a tiny bore in the ball and can sustain pressures of up to 500 pounds per square inch. There is a strong emphasis on design for high-pressure settings. 

What are they used for?

Low-Pressure Ball Valves

For flow limitation, low-pressure ball valves benefit from a high-pressure seal and a low-pressure design, making them an excellent choice. However, although gate valves are more efficient and simpler to operate than ball valves, they require more torque and are thus more costly. 

High-Pressure Ball Valves

High-Pressure Ball Valves are intended to manage high-pressure fluids while also allowing for free flow of the fluid. They may be used in flange connections and pipe systems, among other applications. When they are closed, they enable the safe separation of system fluids. Water hammering can occur if these fittings are not used in a flanged connection.

Final Thoughts

Although high-pressure ball valves are often used in chemical facilities, there are many considerations to make when selecting a valve for high-pressure process activities, including the material of the valve and its leaking characteristics. 

Before choosing between low-pressure and high-pressure ball valves, it is essential to grasp the distinctions between the two kinds of ball valves. When it comes to systems that demand dependable shutdown power, high-pressure ball valves are the most commonly used. It is common in the oil and gas sectors to see them used. Back-pressure valves, suction controllers, and recirculation valves are all examples of applications for these devices. 

If you’re in the market for ball valves, you have various options to choose from. Even though you may get them from the traditional searches, it is preferable to purchase from a recognised expert provider such as Dawsonstech since your dimension and measurements will most likely be quite exact.
