Pipeline Ball Valve Function

Flow Control in Pipelines

A pipeline ball valve helps control how fluids move. Its main job is to manage the flow rate. You turn the handle to open, close, or partly block the pipe. This lets you control water, gas, or oil in pipes. Ball valves react fast, so you can change things quickly.

Here are the main jobs of pipeline ball valves in industry:

1. Flow Regulation: You change the flow rate by moving the valve.

2. Pressure Control: You keep the pressure safe and steady.

3. Isolation of Flow: You stop the flow for repairs or emergencies.

Ball valves work well in oil and gas pipes. They give a tight shut-off and quick action. The V-shaped ball helps control the flow and keeps it steady. You see these valves used in many parts of pipeline work. Floating ball valves are good for low and medium pressure. Trunnion ball valves are best for high pressure.

Ball valves can control flow rates very closely. They respond quickly, so your system stays efficient. The table below shows how ball valves compare to other types:

TANGGONG VALVE makes ball valves with low pressure drop. Fluids move easily, so you save energy. You can get custom valves for your needs. These valves last longer in tough places and need less care.

Shut-Off and Sealing Performance

Pipeline ball valves give strong shut-off and sealing. When you turn the handle, the ball blocks the flow. This makes a tight seal and stops leaks. Sealing is very important in oil and gas pipes to keep things safe.

Modern ball valves use new sealing methods. Some have tiny textured surfaces to seal better. Others use an annular jacket and spring energizer. This keeps the seal strong even when temperatures change. Special seat materials and self-adjusting parts keep the seal tight. These features stop fluid from leaking past the seal.

Operators pick sealing methods based on pipe size, pressure, and fluid type. Soft seats are good for low and medium pressure. Metal seals last longer in high heat and pressure. Back-up seals help in high-pressure jobs.

Industry rules help check shut-off performance. Pipeline valves must pass strict tests like API 6D, API 607, and ISO 15848-1. These rules require leak, fire, and pressure tests. The table below lists some key standards:

TANGGONG VALVE ball valves are known for great sealing. High-pressure models use strong metal seals. These valves stop leaks and keep your system safe. You spend less time and money fixing them. They last long and are easy to care for, making them a smart choice.

Tip: Always check the sealing method and shut-off rules before picking a pipeline ball valve. This helps keep your piping system safe and working well.

Ball Valve Structure

Main Components

You can understand a pipeline ball valve better by looking at its main parts. Each part has a special job in the structure. The table below shows the key components and what they do:

You will find that the structure of a ball valve uses strong materials. Common choices include carbon steel, stainless steel, duplex steel, and nickel alloys for the body. The ball often uses stainless steel or special coatings for better performance. Seats can be soft, like PTFE or PEEK, or metal, like Stellite. These materials help the valve last longer and work well in tough piping jobs.

TANGGONG VALVE offers many options for body, seat, and seal materials. You can pick the right structure for your pipeline based on pressure, temperature, and the type of fluid.

Working Principle

The operation of a ball valve is simple but very effective. You can think of it like a water faucet with a ball inside. When you turn the handle, the ball rotates. The ball has a hole through the middle. If the hole lines up with the pipeline, fluid flows through. If you turn the ball 90 degrees, the hole blocks the flow, and the valve closes.

• The ball rotates inside the valve housing.

• Turning the handle or actuator moves the shaft, which spins the ball.

• When the hole is open, fluid moves easily through the valve.

• When you turn the ball, the hole faces away from the flow, and the valve stops the fluid.

This simple structure lets you open or close the valve quickly. You get fast shut-off and easy flow control. Some valves use pneumatic actuators for even faster operation. These valves respond quickly to signals and help keep your system safe.

TANGGONG VALVE designs its ball valves for smooth operation and reliable sealing. You can trust their valves to work well in many types of pipelines.

Floating vs. Trunnion Designs

You will see two main types of ball valve structure: floating and trunnion-mounted. Each type has a different way of supporting the ball and controlling the operation.

• Floating Ball Valve: The ball floats inside the valve. Fluid pressure pushes the ball against the seat to make a seal. This design works best for small and medium pipes with low to medium pressure. It has a simple structure and costs less. You may need more force to turn the valve when pressure is high.

• Trunnion Ball Valve: The ball is held in place by supports called trunnions. This keeps the ball steady and makes it easier to turn, even under high pressure. Trunnion valves work well for large pipes and high-pressure jobs. They have a more complex structure and cost more, but they give better performance in tough conditions.

Here is a table to help you compare the two designs:

You should choose the right structure based on your pipeline needs. Floating ball valves are good for simple jobs. Trunnion ball valves are better for high-pressure and large pipelines. TANGGONG VALVE gives you both options, so you can match the valve to your system for the best operation and sealing performance.

Tip: Always check the pressure, pipe size, and fluid type before picking a ball valve structure. The right choice will give you safe and efficient flow control in your piping system.

Types of Pipeline Ball Valves

There are different types of pipeline ball valves. Each type has special features for certain jobs. Knowing about these types helps you pick the best valve for your pipeline.

One-Piece Ball Valves

One-piece ball valves have a small, single-body shape. They are light and simple to put in. These valves do not cost much. The flow path is a bit smaller than the pipe. They are good for turning flow on or off in low-pressure systems. You can use them with hot fluids or fluids that might turn solid. There are different ways to connect them, like threaded, flanged, or wafer. The strong body stops leaks and keeps the seal tight.

• Small and light

• One-piece body is strong

• Saves money

• Works in low-pressure and hot jobs

• Many ways to connect

Two-Piece Ball Valves

Two-piece ball valves have a body made of two parts. You can take them apart to clean or fix them. This gives you more options than one-piece valves. They are easier to care for and use in more places. The table below shows how one-piece, two-piece, and three-piece ball valves are different:

Three-Piece Ball Valves

Three-piece ball valves are easy to fix. You can take out the middle part for repairs. You do not need to cut the pipe. This saves time and lowers leak risk. You also save money because you do not replace the whole valve. The table below shows the main good points:

Full Welded Ball Valves

Full welded ball valves have a body that is fully welded. This makes them very strong and stops leaks outside the valve. They are best for high-pressure and hot pipelines. You often see them in underground gas or fuel lines. The welded body keeps the flow safe and lasts a long time. The table below shows where these valves work best:

TANGGONG VALVE sells all these types of pipeline valves. You can pick from many sizes, materials, and ways to connect. The company can also make custom valves for your pipeline needs.
