Ball Valves

SIO manufactures top-quality ball valves that clients can freely customize. Ball valves are a form of shut-off valves that will control the flow or either gas or liquid. This can be done by using a rotary ball that has a bore. By turning the ball 90 degrees, the gas or liquid is blocked or allowed to flow through. They are known to provide stable sealing even when they are not used for a period of time. They also feature a longer lifespan. In addition, they have better resistance to contaminants making them a more popular choice among other valves.

Trust SIO to produce only the best ball valves for all your gas and liquid handling applications!

    Ball Valve Manufacturer

    Ball valves are fast-acting quarter-turn valves that use a rotating ball in transferring media flow through a system. Thanks to their tight shut-off feature, they are gaining significance in multiple industries. Ball valves are used in oil and gas industries, petrochemicals, power industry, pipelines, and practically any application that requires fluid shut-off.

    Ball valves come in different types and have different add-ons, which can be overwhelming to take in. Also, while ball valves are mainly used for on/off applications, some types have become useful for throttling applications, like slurry valve and valves used in food and beverage. All of these make it challenging to choose which ball valve type best suits your application.

    Benefits of Using Ball Valves

    3-way-control-valve

    Cost-efficient

    Companies can find a wide variety of low-cost ball valves to solve a variety of engineering problems. Ball valves come in a variety of materials, including brass and steel.

    Corrosion-resistant

    Most of the ball valves are made of metal and corrosion-resistant materials that increase their lifespan. Ball valves are commonly used in industries that deal with abrasive chemicals.

    Suitable for extreme environments

    Ball valves are made of metal which is why they can withstand extreme conditions. These valves are commonly used in high temperature and high pressure as well as low pressure and low-temperature environments. Ball valves can also withstand hydraulic shock, intense vibrations, and extreme flashing.

    Standard and specification of Ball Valves

    The following standards should be present in the ball valve you are going to buy for industrial purposes-

    Stop Valve

    There is only a 90-degree rotation allowed by this stopper. To accurately regulate flow, it is often used in industries, such as petrochemicals and chemicals, workstations, plumbing services, and other essential machinery. Furthermore, it is a safety feature that ensures that the flow is completely stopped.

    Swing Check

    A swing check provides the benefits of a check valve to a ball valve. It prevents media flow from reentering the system.

    Position Indicators

    The direction of the flow is indicated using a position indicator. A ball valve with a multi-port is commonly equipped with this device. Another application is to ensure that the valve is properly aligned. A thorough understanding of valve operation is essential for industrial processes to avoid damage and serious injuries

    Fire-safe Design

    An additional metal seat provides fire safety for the ball valve. It is particularly useful when the system temperature rises to levels that may damage the soft seat. A backup seat will provide support in case the soft seat softens or melts, which could cause a fire if leakage occurs.

    Anti-static Device

    The anti-static device prevents static electricity from accumulating on valves due to valve friction. An accumulation of static can be a fire hazard, especially if the media is flammable.

    Standard Face-to-face Dimensions

    Dimensions that conform to ASME standards enable the valve to be replaced or modified with valves made by other manufacturers.

    Blow-out Proof Stem

    Having a blow-out proof stem in a ball valve ensures safe and efficient industrial operations. As a result, the valve stem won’t fly out or blow out when too much pressure is applied to the ball valve.

    Common Ball Valve Applications

    Before buying a ball valve, it is essential that you understand the specific requirements of your application. This is for the ball valve to function efficiently, and safely, and have a long service life. To guide you, here are the important factors that will help you select the right valve that will serve you for many years. Ball valve is commonly used in Marine, water distribution systems, and others.

    Oil and Gas Industries

    In the oil and gas industries , the pipelines used mostly need to be manually operated and should withstand critical service conditions. These will include extremely high pressures and temperatures or severely low pressures and cryogenic temperatures. These industries also include applications with high corrosion and erosion to which the ball valves must endure.

    Pipeline Industries

    In most applications, ball valves used in large pipelines need to be “piggable.” This means that the valve bore should have a diameter that fits a pipeline pig to perform inspections, cleaning, and maintenance tasks. In most services, full bore ball valves are used, which have a similar size with the pipelines when in an open position.

    Food and Beverage Industries

    Food and beverage industries require strict sanitary guidelines to which ball valves must comply. Some of these require the valves to have smooth surfaces without any pores and crevices in which materials and bacteria could build up. The materials the valves are made should not affect, like contaminate or degrade, the product.

    Water and Wastewater

    The materials of ball valves used in teflon lined water and wastewater should be able to endure the chemical substances present in the process flow. Most of these applications may involve water that contains solids and other types of materials that could lead to buildup. The valves used must be able to handle material buildups and clogging to avoid disrupting the entire system.

    Pharmaceutical and Chemical Industries

    Ball valves used in the pharmaceutical and chemical industries should adhere to strict safety standards depending on the process media. Materials of the valves must be non-reactive with any chemicals they will come in contact with and have excellent resistance to corrosion and abrasion. The ball valves used in these industries are required to provide accurate flow control and avoid any chances of leakage of dangerous materials.

    How to Choose the Right Ball Valves for Your
    Industrial Applications

    Before buying a ball valve, it is essential that you understand the specific requirements of your application. Ball valve is different from globe valve and gate valve. This is for the ball valve to function efficiently, safely, and have a long service life. To guide you, here are the important factors that will help you select the right valve that will serve you for many years.

    Factors to Consider When Choosing Ball Valves

    The Flow Media

    The characteristics of the process media have significant effects on the entire system, including how the ball valve operates. It is essential that you determine them to make sure you use the right ball valve for your application. The factors you need to take into account include, but are not limited to:

    The Application and Function

    Ball valves may need to perform other functions depending on the application. The range of ball valves available means they are well-suited for a variety of operations.

    For example, should the valve completely start and stop the flow or is it also used for throttling? Does it need to regulate or release system pressure? How much leakage can the system tolerate? How accurately should the valve be able to control the flow? Identifying the specific functions of your ball valve will lead you to the right type that will deliver safely and effectively.

    The Working Temperature

    The shut-off feature of ball valves is also used to manage hot and cold liquids. It is equally important you identify the temperature of the process media as this will help you choose the appropriate make of your ball valve. Different materials are used in the manufacture of industrial valves including stainless steel, carbon steel, PTFE, PVC, etc. Each one of them is fitted for specific temperature ranges.

    The Working Pressure

    The shut-off features of ball valves are designed to handle different pressures of liquid. It is important that you determine the pressure range that will flow through the ball valve. This allows you to choose the appropriate size and maximum pressure capacity to handle such an application.

    Maintenance and Cleaning Requirements

    Maintenance and cleaning requirements are also important since they affect the operation of the entire system. Is it easy to clean the valves? How regularly do the valves require maintenance? These questions help you determine whether the valves are ideal and practical for the overall application.

    Working With Other System Elements

    When choosing a ball valve, you also need to consider how well it will work with the other components of the system. For example, larger valves are capable of higher pressures but they are not suitable where there is limited space.
