Double Offset Butterfly Valve
TVCCL double offset butterfly valve, known as a high-performance butterfly valve, has an extensive range of applications nowadays.
The double offset structure in the stem center deviates from the centers of the disc and valve itself. Upon these features, the disc can leave the seat quickly. Furthermore, reducing unnecessary squeezing and scraping between the two parts. The wearing process then is decreased, and the valve prolongs its operation life.
TVCCL double offset butterfly valve, also known as a high-performance butterfly valve or a double eccentric butterfly valve, is a type of butterfly valve designed to improve sealing and reduce wear on the valve components. The "double offset" refers to the way the stem is positioned in relation to the disc and the valve body, which is different from a conventional (centric) butterfly valve. Reduced Wear and Tear: The double offset design minimizes the contact between the disc and the seat during operation, reducing wear and extending the valve's lifespan.
Features
- Protecting Stem Blowout caused by pressure and optional Anti-electrostatic.
- Tangentially positioned half in disc and half in stem to eliminate of failure.
- A no-screw-floating deign to climate cold flow. This design provides positive tight shut-off of seat. Surface roughness is 125-200AARH.
- Tangentially positioned half in disc and half in stem to eliminate potential of failure.
- We have soft and fire safe's seat, we can provide Higa-PTFE, RTFE, UHMWPE etc...
- Higa-PTFE purchase from overseas market; its Load strength is two and a half times of general material Patented floating seat retainer; Bi-direction Zero Leakage.
- Uses RTFE+S.S 316 Stem bush. Has excellent working temperature, Strength rating, and low friction factor. Maintain good seat sealing capa-bility even after high-cycle operations.

Applications
- TVCCL double-offset valves are easier to open and close because they require less operating torque than other valve types, the valve has a higher flow capacity than other types, making it ideal for applications where a large volume of fluid needs to be processed.
- TVCCL double offset butterfly valves feature a flexible seat design that ensures a tight seal, even when the valve is partially open.
- They are versatile and can be installed in both horizontal and vertical positions, making them suitable for a wide range of applications.
More Knowledge about TVCCL valve:
Double Offset Butterfly Valvecan be used for shutoff and throttling control.High-Performance Double Offset Butterfly Valve structural feature is that the axis of the valve stem is both deviated from the center of the disc and away from the center of the body. The double eccentric effect allows the disc to be quickly disengaged from the valve seat after the valve is opened, which greatly eliminates unnecessary over-squeezing and scraping of the valve flap and the valve seat, reduces the opening resistance, reduces wear and get longer of seat life. The double-offset butterfly valve is used in the pipe systems requiring higher pressure resistance. The disc is positioned in the center of the pipe bore and arranged to increase sealing ability and decrease wear to the valve. TVCCL high-performance butterfly valve is ideal for handling water, oil, steam, and gas in a cost effective, light weight design.
