About Triple Eccentric Butterfly Valve:
A triple eccentric valve, also known as a triple offset valve, is a high-performance valve designed to provide reliable and precise flow control in demanding applications. Its unique design features three offsets, which ensure a tight seal and reduce wear and tear on the valve components. These valves are commonly used in industries where high pressure, high temperature, and critical shutoff are required, such as in oil and gas, petrochemical, power generation, and shipbuilding. As a top Triple Eccentric Butterfly Valve Manufacturers in India, we focus on quality and performance.
The design of the valve incorporates three distinct offsets that differentiate it from traditional butterfly valves:
1. First Offset: The shaft is offset behind the centerline of the sealing surface, allowing the disc to rotate without interference.
2. Second Offset: The shaft is also offset from the centerline of the pipe and valve, creating a cam-like motion for the disc.
3. Third Offset: The sealing surface of the disc is conical rather than flat, which eliminates rubbing and minimizes friction during operation.
These offsets ensure that the disc only contacts the seat at the final moment of closure, reducing wear on the sealing surfaces and extending the valve’s lifespan. The body and disc of the valve are typically made from durable materials such as stainless steel, carbon steel, or exotic alloys, depending on the application requirements. The seats are often laminated or solid metal, providing a reliable seal even in harsh conditions.
Operating Mechanism:
The working of the valve majorly depends on the motion produced by the three offsets. The shaft rotates in response to movement of the actuator or handle, which moves the disc away from the seat in a manner akin to a cam. By ensuring that the disc does not come into contact with the seat until the valve is almost closed, this motion helps to minimize wear and friction. The conical sealing surface of the disc contacts with the seat as the valve gets closer to closing, producing a tight metal-to-metal seal. With this design, a bubble-tight cutoff is possible even in conditions with high temperatures and pressure. Triple Eccentric Butterfly Valve Manufacturers in India operate with reduced rubbing and friction, which reduces maintenance needs and lengthens service life.
Benefits:
1.Bubble-Tight Seal: Offers a dependable seal even at elevated temperatures and pressures.
2.Decreased Wear and Tear: The valve lasts longer when there is less friction and contact between the disc and seat.
3.Low Maintenance: Less regular maintenance is required due to durable designs and decreased wear.
4.High Performance: Suitable for essential applications requiring accurate flow control and shutdown.
5.Adaptable Use: Capable of managing an extensive variety of fluids, such as gases, liquids, and slurries.
