A triple offset butterfly valve is a type of butterfly valve that is designed to provide a reliable and tight sealing performance even in high-temperature and high-pressure applications.The triple offset design of the valve ensures that the seal ring is constantly in contact with the sealing surface throughout the entire range of travel, providing a bubble-tight seal. This design also reduces friction between the seal ring and the sealing surface, resulting in a longer service life and better operating efficiency.Triple offset butterfly valves are commonly used in industries such as oil and gas, power generation, chemical processing, and pulp and paper. They are particularly popular for applications that require bi-directional shut-off capabilities or for handling abrasive, corrosive, or high-temperature fluids.At Supcon, we offer a wide range of triple offset butterfly valves to meet the needs of various applications. Our valves are manufactured to stringent quality standards, ensuring exceptional performance and reliability.

Triple Offset Butterfly Valve manufacturer in the topmost Triple Offset Butterfly Valve manufacturer in 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. 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.

Electric Triple Offset Butterfly Valve The electric triple eccentric butterfly valve adopts a three-dimensional eccentric structure, and has the advantages of strong applicability, small torque force, less friction, and good sealing performance. When the electric triple eccentric butterfly valve is opened, the disc will instantly separates the sealing surface of the seat, which reduces friction and interference with the sealing surface, and greatly improves the service life of the butterfly valve. Moreover, the electric triple eccentric butterfly valve disc and the seat sealing surface are made of stainless steel, so that the butterfly valve has reliable guarantee of corrosion resistance, temperature resistance, pressure resistance and wear resistance, and is a high-performance energy-saving electric butterfly valve.
