Double Offset Butterfly Valve Design

Key Features and Structure

The double offset butterfly valve is special because of its design. It uses two geometric offsets to work better. The first offset moves the shaft away from the disc’s center. The second offset puts the shaft behind the sealing surface. These changes help the disc lift off the seat when you open the valve. The disc does not rub against the seat. This lowers friction and helps the valve last longer. You get smoother movement and less damage.

The second offset makes the disc move like a cam. The disc only touches the seat right before closing. This means you do not need much force to use the valve. You also get a tighter seal. The valve works well in high-pressure and hot jobs. It is good for oil, gas, and chemical plants.

TANGGONG VALVE uses strong materials for these valves. The body is often made from ductile iron or stainless steel. The seats use Stellite or reinforced Teflon. These materials handle high pressure and heat. They also last a long time.

Some double offset butterfly valves have new technology. Some models have smart sensors. These sensors show real-time data about flow and pressure. Other models use recyclable materials to help the planet. Some valves have safety locks for extra safety. You can even change the design to fit your needs.

How Double Offset Differs from Other Types

You might wonder how double offset valves are different from other types. The main types are concentric, double offset, and triple offset.

A concentric butterfly valve has its shaft in the middle. The disc always touches the seat when you open or close it. This causes more friction and faster wear. You need more force to use it. It works best for low-pressure jobs.

The double offset butterfly valve moves the shaft away from the center and behind the seat. This design means the disc and seat touch less. You get less wear and a higher pressure rating. The valve lasts longer and needs less fixing.

Triple offset butterfly valves add a third offset. This makes a cone-shaped sealing surface. The disc and seat only touch when the valve is fully closed. You get a bubble-tight seal. This type is best for very high pressure and temperature. It lasts longer but costs more.

• Triple offset valves stop leaks with their three-flanged design.

• Double offset valves seal well but not as well as triple offsets.

• Triple offset valves are best for tough jobs, while double offset valves work for most jobs.

Double offset butterfly valves give you good sealing, long life, and save money. They work in many industries. You can use them for water, steam, and chemicals. TANGGONG VALVE uses smart engineering so you get reliable results every time.

Tip: If you need a valve for very high pressure or heat, pick a triple offset valve. For most jobs, a double offset valve gives you the best value and performance.

TANGGONG VALVE Butterfly Valve Advantages

Reduced Seat Wear and Enhanced Sealing

You want your valves to last a long time. You also want them to work well. Double offset butterfly valves help with this because of their smart design. When you open the valve, the disc moves away from the seat quickly. This lowers friction and keeps the seat from wearing out fast. You do not need much force to use the valve. This saves energy and stops damage.

• The special shape of double offset butterfly valves lowers friction.

• The disc lifts off the seat as soon as you start opening. This reduces wear and makes the valve last longer.

• You get a tight shut-off with less force. This means less wear and longer use.

The double offset design helps you get a better seal. Two stem offsets let the seat move away from the disc when opening and closing. This movement lowers contact and wear. It is important for keeping a tight seal. You can trust this valve to stop leaks, even if pressure or temperature changes.

You can use high performance butterfly valves from TANGGONG VALVE for many jobs. These valves give you steady flow control. They help you meet strict safety needs. If you need class vi shut off valves for zero leaks, you can find them in the TANGGONG product line.

Tip: Pick double offset butterfly valves if you want less fixing and better sealing in your system.

High Pressure and Temperature Performance

You need valves that work in tough places. TANGGONG VALVE makes double offset butterfly valves for high pressure and heat. You can use them in oil, gas, chemical, and power plants. The valves use strong materials like stainless steel, ductile iron, and special alloys. These materials fight rust and last longer.

The valves pass many tests and meet top standards. You can see the certifications in the table below:

You get more than just strength. The double eccentric design gives you a tight seal under pressure. This feature lowers leaks and keeps your system safe. Reports show double offset butterfly valves can last up to 25% longer than standard valves. You spend less time and money fixing them.

Here are some key benefits you get with TANGGONG VALVE:

You can use quarter turn operation for fast and easy control. TANGGONG VALVE gives you many choices for butterfly valve actuation. You can pick manual, electric, pneumatic, or hydraulic. You get the right fit for your needs.

If you need high performance butterfly valves for tough jobs, you can look at triple offset butterfly valves. For most uses, double offset gives you the best mix of value, performance, and safety.

FAQ

What is a double offset butterfly valve?

This valve has two offsets in its design. The shaft is not in the middle of the disc. It sits behind and off to the side. This helps the disc move away from the seat fast. There is less rubbing, so the valve lasts longer.

Where can you use double offset butterfly valves?

You can use these valves in many places. They work in water plants and power stations. They are also used in oil and gas systems. Chemical factories use them too. These valves do well with high pressure or heat.

How do you choose the right seat material?

Tip: Use PTFE or RTFE seats for chemical jobs. Pick metal seats if you need to handle high heat. If you are unsure, ask TANGGONG VALVE for advice.

What certifications do TANGGONG butterfly valves have?

Can you automate a double offset butterfly valve?

Yes, you can automate this valve. You can use electric, pneumatic, or hydraulic actuators. This lets you control the valve from far away.
