Advantages of Ball Valve
High Efficiency
Due to the size of the opening in the ball, ball valves are considered high recovery valves since they have a low-pressure drop and high flow capacity. There is little turbulence or resistance to fluid flow when the valve is fully open.
Convenient Usage
As a result of their simple quarter-turn (90-degree) operation, ball valves are efficient and convenient to use. As the valve is relatively lightweight and small, it is also easy to install and remove.
Low Maintenance
Compared to other types of valves, ball valves are simple and require less maintenance. Because the ball valve stem rotates without axial movement, the packing seal on the valve stem does not easily wear or fail. Ball valves are easy to disassemble and repair, and worn parts can be easily replaced.
Cost-efficient
The cost of ball valves is affordable compared to more complex valve types. Also, as they have low maintenance needs, they’re cheaper to maintain/implement in the long term.
Types of Ball Valve
Flanged ball valve refers to a ball valve that connects valves and pipes through flanges. Flanges are joints between pipes and a way of connection. Flange connection is composed of flange, gasket and bolt and nut connection. It is a detachable connection that can be.
2 inch high pressure ball valve refers to a ball valve with an inner diameter of 2 inches and a pressure range between 300lb-2500lb. The inner diameter of the valve is generally marked as inches internationally, and dn in China.
1 inch high pressure ball valve refers to the nominal diameter of the valve is 1 inch, the inner diameter is about 25mm, and the outer diameter is 33.4mm, which is dn25 valve or one inch ball valve.
The high pressure pneumatic actuated ball valve is composed of a double (single) acting pneumatic piston actuator and a high pressure ball valve, and is an integrated self-control valve driven by compressed air. It can also adopt intelligent.
The high pressure electric actuated ball valve is composed of an electric actuator and a ball valve. High pressure electric actuated ball valve is also called motorized ball valves, motor operated ball valve or electrically operated ball valve. It is a pipeline component for industrial automation process control, usually used for remote opening and closing (connecting and cutting off medium) control of pipeline medium.
High-pressure stainless steel ball valves refer to valves used in pipelines with a pressure range of 300lb-2500lb. Because most of them are made of stainless steel, high-pressure stainless steel ball valves can also be referred to as ss ball valves.
Application of Ball Valve
Oil And Gas Industry
In the petroleum industry, the job of regulating crude oil as well as natural gas flow through pipelines is handled by ball valves. The fact that they can function in such tough conditions and also be under high pressure makes them an integral part of this field.
Chemical Processing
In chemical processing plants, the flow of different chemicals is controlled by ball valves. Their materials can be selected to be resistant to corrosion, thus enhancing their longevity and safety.
Food And Beverage Industry
In the food and beverage industry, sanitary ball valves are utilized for handling the flow of liquids, such as water, juices and dairy products. These valves are made to meet stringent hygiene standards so as not to have any contamination.
Pharmaceutical Industry
Precise control of fluids in medicine manufacturing by the pharmaceutical industry depends on ball valves. The cleanliness standards that must be met for these valves are stringent to prevent contamination.
Water Treatment Plants
The flow of water through various stages of the treatment process in water purification plants is controlled by ball valves. They are responsible for regulating the inflow of raw water, managing flows through filtration systems, controlling addition of chemicals and ensuring an effective distribution of treated water.
Materials Used in Ball Valve
Brass
Brass, an alloy primarily composed of copper and zinc, is easily recognized by its dull yellowish to reddish hue, which varies based on zinc content. It is a popular choice for ball valves due to its strength, durability, and ability to handle high temperatures and pressures. Brass also boasts antimicrobial properties thanks to its copper content, which helps prevent microbial growth on its surface.
Stainless Steel
Stainless steel is a high-strength alloy known for its excellent corrosion resistance, achieved through its high chromium content and, in many cases, nickel. It maintains its strength and durability even under high temperatures and pressures, making it a reliable material for demanding applications.
Polyvinyl Chloride
Pvc is a tough, rigid plastic material known for its durability and affordability compared to brass and stainless steel. While it generally has lower strength and a lower temperature and pressure rating (up to 150 psi and 140°f, respectively), pvc is resistant to corrosion and most acids, bases, and salt solutions.
Polypropylene Ball Valve
Polypropylene is a versatile, resilient, and lightweight thermoplastic derived from propylene monomer. It is known for its high resistance to many acids and bases, although its compatibility with organic compounds and solvents is somewhat limited. The material's chemical resistance diminishes at elevated temperatures, with a maximum service temperature of 82°c.
Glass Fiber-reinforced Polypropylene Ball Valve
Glass-fiber-reinforced polypropylene incorporates glass fibers into polypropylene to enhance its dimensional stability, rigidity, and chemical resistance, while also reducing its thermal expansion coefficient. With a 40% glass fiber composition, the heat deflection temperature can reach up to 150°c at 264 psi.
Polyvinylidene Difluoride Ball Valve
Pvdf is a high-purity, robust thermoplastic fluoropolymer with a high molecular weight. It is produced through the free-radical polymerization of vinylidene fluoride gas. Additionally, pvdf is known for its resistance to abrasion.
