CAN A BALL VALVE BE USED AS A CONTROL VALVE?

-

The most common type of valve available today is the ball valve if you have basic valve knowledge. Ball valves are typically quarter-turn valves with a perforated ball in the middle to control flow. Although these valves are known for their durability and excellent shutoff, they do not always provide very precise control. It's okay to use a ball valve as a control valve when there are certain conditions.


Due to their cost effectiveness, ball valves are still commonly used despite not being the best flow control device. An application that doesn't require precise control and adjustment can be handled by a ball valve. Ball valves, for example, should be able to maintain a given level within a few inches of a large tank. We are the leading ball valve manufacturer in India. 


When Choose your ball valve, you must take into account all the conditions of the process. It includes the material or product, the size of the pipe, the flow rate, etc. Ball valves may not be the best choice if you're trying to control an expensive material that you don't want to waste.



Due to their small adjustment range, ball valves do not provide very precise adjustments for large amounts of flow. It is also difficult to control precisely because there is a 'slop' or 'play' between the stem and the ball. Additionally, ball valves cannot be finely adjusted near their "closed" and "open" positions because of the torque needed to adjust them.


A globe valve will provide more accurate control over your application than a ball valve. Because globe valves are good at regulating flow, they are considered the industry standard for control valves. Ball valves are better for on/off control without causing pressure drops.


Depending on your application, you may want to consider different types of ball valves if you need to control your process with one. Some situations require a trunnion or v-port ball valve that performs better and can be adjusted more precisely.


There is an additional mechanical anchoring of the ball at the top and bottom of the trunnion ball valves. The ball and stem are connected by a splined or keyed stem connection that eliminates play. Ball valves with V-ports have a V-shaped ball rather than a round hole. With its tapered opening, this allows for more linear flow, which allows for more control.

Motorized Sanitary Butterfly Valve Description: There is a type of valve widely used in the sanitary industry called the sanitary butterfly valve. This type of valve is called a butterfly valve not because of its shape, but because it has a relatively simple structure, is convenient to operate, looks compact, and is flexible. This device is called a sanitary butterfly valve because the butterfly is also a small and flexible insect. A motorized sanitary butterfly valve is a stainless steel butterfly valve that is operated by an electric actuator. The valve is also known as a food-grade motorized butterfly valve or a hygienic electric butterfly valve. The food sanitary electric butterfly valves are widely used in food, pharmaceuticals, cosmetics, clean steam, alcohol, beverages, and biochemical industries. Electric sanitary butterfly valves have precision polished and sterilized flow channels, sealed with PTFE, and easy-to-clean corners. A standard electronic polishing process is used on...

If you've ever wondered how those big, round valves work that is often used in water lines and other types of piping, you're in luck. This blog post will give you a comprehensive guide to butterfly valves, including how they work and the different types that exist. You'll also learn about the advantages and disadvantages of butterfly valves so that you can decide if they're the right choice for your needs. Introduction A butterfly valve is a quarter-turn valve that regulates the flow of liquids and gases by opening, closing, or partially obstructing a passageway. Butterfly valves are named for their disc-shaped bodies and wing-like handles. Butterfly valves are often used in systems that require a frequent operation, such as in HVAC (heating, ventilation, and air conditioning) systems. They are also well suited for applications where space is limited, as they are much smaller and lighter than other types of valves. There are two main types of butterfly valves: lug-type ...
