Trunnion ball valves are used in the distribution of water and steam, as well as other fluids such as air, oil and gas. They have a much higher flow rate than standard rotary valves and can handle very high pressures. Trunnion ball valves come in many different sizes and shapes to suit your application.
Trunnion ball valves are one of the most common types of valves used today. Trunnion ball valves are available in a wide range of materials including brass, stainless steel and aluminum. The key difference between trunnion ball valves and standard rotary valves is that these valve bodies have a longer stem that extends from the body into the valve seat, making them faster acting.
Two moving parts are used in trunnion ball valves.
Trunnion ball valves use two moving parts: the stem and stem cap/crown (sometimes referred to as head or seat). The stem cap/crown slides onto the stem in order to create a seal between them so that there’s no leakage through the valve body itself.
Trunnion ball valves are used in applications where a high flow rate and low-pressure drop are required. They have a large opening area and are capable of handling large flows. The valve body is mounted in a circular trunnion, which allows the valve to rotate about its axis. This is important for many applications, as it allows for more accurate control of the flow rate.
Both manual and automatic trunnion ball are offer
Trunnion ball valves are available in both manual and automatic operation. The manual model has some advantages over the automatic version, since it is easier to control manually. However, the automatic version has several advantages over its manual counterpart, such as improved stability and reduced maintenance requirements.
The trunnion ball valve is a specialized type of ball valve that is designed for high-pressure applications. The trunnion ball valve has a unique design that includes a floating ball that is supported by two trunnions, or pivots. This design allows the trunnion ball valve to withstand higher pressures than a standard ball valve. The trunnion ball valve is typically used in oil and gas pipelines, as well as in other high-pressure applications. The trunnion ball valve is available in a variety of sizes and designs to meet the needs of different applications.
What is the difference between a floating ball valve and a trunnion ball valve?
Through the valve stem’s top shaft and the trunnion’s bottom shaft, a trunnion ball is fastened to and centered inside the valve body. A floating ball and the valve body are only connected via the valve stem. The floating ball therefore “floats” in the valve seats.
Trunnion ball valves are one of the most reliable and versatile valve designs available on the market today. Used in a wide variety of industries, from oil and gas to chemical processing, these valves are able to provide superior performance in even the most demanding applications.
Trunnion ball valve design
While there are many different types of ball valves available, the trunnion design is widely considered to be the best option in terms of both reliability and performance. In a trunnion ball valve, the ball is supported by two metal seats (known as trunnions) that are located on either side of the valve body. This design provides a number of advantages over other types of ball valves, including:
· Reduced wear
The trunnion support design minimizes wear on the ball and seats, resulting in a longer lifespan for the valve
· Improved sealing
The trunnion design provides a more reliable seal than other types of ball valves, making it an ideal choice for applications where leakage is not tolerable.
· Greater strength
The trunnion support design gives the valve greater strength and durability, making it ideal for use in heavy-duty industrial applications.
Trunnion ball valve vs ball valve
There are many different types of valves on the market today, each with their own advantages and disadvantages. Two of the most popular types are trunnion ball valves and ball valves. Which one would suit your needs the best, then? Trunnion ball valves have a number of advantages over ball valves. First, they are less likely to leak because the ball is supported by trunnions on both sides. This design also allows for a higher-pressure rating than ball valves. Additionally, trunnion ball valves are easier to maintain because the internals are more accessible.
However, there are some disadvantages to trunnion ball valves as well. They are typically more expensive than ball valves, and they can be difficult to automate. Additionally, they are not as widely available as ball valves.
So, which type of valve is best for you? Your requirements and financial situation actually determine this. If you need a high-pressure valve that is easy to maintain, then a trunnion ball valve is a good choice. However, if you need a lower-cost valve that is widely available, then a ball valve may be a better option.
