Triple Offset Butterfly Valve
The Triple Offset Butterfly Valve is a state-of-the-art addition to our range of high-quality industrial valves. This advanced valve is designed to provide exceptional performance, superior flow control, and enhanced durability in demanding industrial conditions.
Constructed with precision engineering, the Triple Offset Butterfly Valve features three separate offsets. Two of these offsets are placed in the position of the shaft in relation to the centerline of the disc and the body. The third offset, which gives this valve its name, is the design of the seating surface, creating a conical shape. This unique design enables the disc to be fully rotated, opening and closing the valve without any friction.
The absence of friction not only reduces wear and tear, resulting in a longer lifespan for the valve, but also ensures a tighter seal when the valve is closed. This makes the Triple Offset Butterfly Valve particularly effective for handling high-pressure, high-temperature, and corrosive flow applications.
The body of the Triple Offset Butterfly Valve is crafted from robust materials, providing resistance to corrosion and ensuring it can withstand harsh operating environments. It’s designed to handle a variety of media, including liquids, gases, and semi-solids, making it versatile across multiple industries, from oil and gas to power generation and chemical processing.
One of the standout features of the Triple Offset Butterfly Valve is its excellent flow control capabilities. The triple offset design allows for precise modulation of flow, responding swiftly and accurately to changes in pressure, temperature, and flow rate. This makes it an optimal choice for systems requiring precise flow regulation.
Despite its complex design, the Triple Offset Butterfly Valves is easy to operate. Equipped with either a manual handle or an actuator, it offers smooth and efficient operation, reducing the effort required to control the flow of media.
In conclusion, the triple offset valve is a high-performing and reliable solution for your flow control needs. Its unique triple offset design, durability, and precise control make it an invaluable asset for a wide range of industrial applications.
Flanged triple offset butterfly valve provides zero leakage through no-rubbing 90-degree rotation across a wide range of pressure and temperature conditions.
Widely used in many industries such as Oil & Gas, Chemical & coal, petrochemical, desalination plants, waterworks, fossils, district heating, nuclear, Iron & Steel, Mining, automotive, shipyards, aerospace.
