Butterfly Valve Manufacturer in USA
SVR Global is a trust-worthy Butterfly Valve Manufacturer in USA with a large selection of Butterfly Valves. Our products have been well received for several years by various prestigious organizations.
What is a Butterfly Valve?
A butterfly valve is a member of the family of quarter-turn, bi-directional, rotary motion valves used to stop, control, or start flow.
Quarter valves are the kind of valves that only require a quarter turn of the disc to fully open or fully close the flow. In order to transition from the completely open to the fully closed position, quarter turn valves simply need to be rotated 90 degrees. They are also known as fast-acting valves for this reason.
The shape and movement of the plug give the butterfly valve its name.
The plug has a rod running through it and is formed like a disc, giving it the appearance of wings. The disc rotates by a quarter when the rod is turned, falling perpendicular to the flow and stopping it. The disc is rotated back to its original position, which is away from the flow in order to restart the flow. To regulate the flow, the valve can also be opened gradually.
Advantages of Butterfly Valve:
- A high-pressure rebound follows the low-pressure decrease.
- Can be installed/removed easily without disrupting the piping system
- Costs less because there is less raw material.
- Design is small & requires little room.
- Durable
- Easy to install and operate
- Energy efficiency has improved.
- Good for on/off and throttling
- Good for slurries
- Large seating area
- Larger sizes are available.
- Less assistance is required.
- Lightweight
- Low operation torque allows for simple operation.
- Low-pressure drop.
- Maintenance is easier, inexpensive and less required.
- No gas pockets
- Numerous actuation methods are available.
- Piping system easily supports the weight.
- Quick operation; little time spent opening or closing.
- Quite accurate.
- Various seat and disc materials are available.
Disadvantages of Butterfly valve:
- Cavitation and choked flow are possible.
- Disc provides little resistance to flow when fully open.
- Due to low-pressure drop, throttling is limited.
- Even in an open state, the valve disc is constantly under pressure and might interrupt the flow.
- Flow turbulence affects disc movement, which is unguided.
- High differential pressure is not recommended.
- Poor sealing.
- Regardless of the setting, a pressure switch occurs over the valve.

Types of Butterfly Valves:
A centric or concentric butterfly valve is the most common type of butterfly valve arrangement.
The stem is in the center of the disc and the disc is in the center of the valve body. The disc stays in the passage, but it provides very little resistance to the flow due to its thinness. When the seat opens or shuts, some portions of the disc are always in touch with or scraping the seat. The seat is subjected to friction every time the valve is utilized as a result of this arrangement.
Concentric butterfly valves are also known as resilient seated butterfly valve as it depends on the flexibility of the seat rubber when the flow is closed, for the reliability of the seal.
Single Offset Butterfly Valve
The shaft is offset from its body center line.
The double eccentric offset butterfly valve is also known as the high-performance butterfly valve or double eccentric butterfly valve.
The shaft is offset both from its body center line as well as the pipe’s center line.
This valve is suitable for thicker media with high pressure due to its design which prevents excessive contact between the disc and the seat. The valve’s balance is controlled by the stem, which is placed behind the circular disc. It allows the disc to self-adjust to the center, ensuring a solid fit. Even when fully opened, the valve does not touch the soft seat, ensuring a longer service life.
Triple offset butterfly valves are another name for triple eccentric butterfly valves.
The shaft is offset from its body center line as well as the pipe’s center line like the double offset butterfly valve. In addition, there is a conical offset shape in its seal & disc connection.
Thermal shocks and pressure peaks are reduced because of the metal sealing, and the design allows for low torque operation. The composite stainless steel sealing ring on the disc of our triple eccentric butterfly valve ensures that there is no leakage. The unique triple eccentric method achieves right-angled rotation with minimal friction. This approach makes the triple eccentric butterfly valve more resistant to high temperature, high pressure, and corrosion than standard butterfly valves. The metal hard seal begins more easily because of the triple eccentric’s unique shape. There is no friction between the disc and the valve body throughout the rotation process when the valve is opened and closed. A zero-friction right-angled rotation was possible thanks to the triple eccentric arrangement. High-frequency opening and shutting applications, as well as harsh applications, call for these valves.
Based on Valve Geometry-
The butterfly valve body construction varies in the ways they are joined:
- Double flanged valve: two bored flanges ensure a free connection of the flanged pipes by bolts.
- Wafer-style valve: four centering through-holes allow to use the same bolts for both pipes;
- Lug-style valve: multiple threaded centering bores secure the valve with several bolts and no nuts;
- Butt-welding ends: both ends of the valve body are welding-ready to be joined to the pipes.

Triple Offset Butterfly Valve manufacturer in USA
SVR Global is the topmost Triple Offset Butterfly Valve manufacturer in USA. We provide high-quality and reliable valves at competitive prices. The triple offset butterfly valve is also known as a Triple eccentric butterfly valve. Because of its metal sealing, the thermal shocks and pressure peaks are getting reduced.
This design allows for low-torque operation. The composite stainless steel sealing on our triple offset butterfly valve ensures that there is no leakage. This makes the valve more resistant to high temperature, high pressure, and corrosion. Whenever the valve body is opened or closed, there is no friction happens between the disc and the valve body throughout the rotation.
Difference between Double offset and Triple offset butterfly valve:
|
Double offset butterfly valve |
Triple offset butterfly valve |
|
A high-performance butterfly valve is a double offset butterfly. Since there is less contact between the disc and the seat, it is perfect for thicker media. They can therefore bear great pressure. |
A triple offset butterfly valve was first created as a water supply shut-off valve. They are now most effective for controlling fugitive emissions and important processes. They are also known as triple eccentric valves. In place of larger and more expensive valves, they make the perfect substitute. |
|
The two offsets in double butterfly valves are:
• A small distance to the right of the centerline.
• The disc and stem are linked somewhere near the centre of the valve. |
The three offsets of a triple offset butterfly valve are:
• At the centre of the disc and the seat. • Situated directly at the bore’s centerline and attached to the stem. • The valve’s centre, where the seat cone’s axis is located. |
Triple Offset Butterfly Valve is used in industries like:
- Power generation
- Oil and gas
- Pulp and paper
- HVAC
- Chemical
- Shipbuilding
Advantages of Triple Offset Butterfly Valve:
- It has a lengthy lifespan
- It has excellent regulating capabilities
- It is easy to open and shut off
- It has a simple structure, compact dimension, and lightweight
