A triple offset butterfly valve is a type of industrial valve used to control the flow of fluids in pipelines. It is called "triple offset" because it incorporates three offsets:
Shaft Offset: The shaft, which connects the valve disc to the actuator, is offset from the centerline of the valve and is typically located behind the seat. This offset eliminates rubbing and friction between the disc and seat during operation, reducing wear and extending the valve's lifespan.
Disc Offset: The disc is also offset from the centerline of the valve body. This offset creates a cam-like action during operation, which ensures a tight seal against the valve seat, even under high-pressure conditions.
Lug or Rotation Offset: The third offset involves the rotation axis of the disc. Unlike traditional butterfly valves where the rotation axis is perpendicular to the pipe flow, in a triple offset butterfly valve, the rotation axis is tilted at a slight angle. This design reduces wear on the seat and seal during opening and closing, further enhancing the valve's performance and durability.
Triple offset butterfly valves are known for their tight shut-off capabilities, high-pressure resistance, and reliability in various applications such as oil and gas, petrochemical, power generation, and water treatment. They are often used in applications where a bubble-tight shut-off is required, even in high-temperature and high-pressure environments.
Triple offset butterfly valves offer several advantages over other types of valves, including:
Bubble-Tight Shut-Off: The triple offset design provides a tight seal between the valve disc and the seat, ensuring bubble-tight shut-off even in high-pressure and high-temperature applications. This feature minimizes leakage, enhances process efficiency, and reduces the risk of product loss or environmental contamination.
Reduced Wear and Longer Lifespan: The offset design reduces friction and wear between the disc and seat, as well as between the shaft and bearings. This results in extended valve lifespan, reduced maintenance requirements, and increased reliability, making triple offset butterfly valves a cost-effective solution over the long term.
High Pressure and Temperature Resistance: Triple offset butterfly valves are designed to withstand high-pressure and high-temperature environments, making them suitable for a wide range of industrial applications, including oil and gas, petrochemical, power generation, and refining.
Bi-Directional Sealing: Unlike some other types of valves, triple offset butterfly valves provide bi-directional sealing, meaning they can effectively control flow in both directions. This flexibility allows for greater versatility in system design and operation.
Low Torque and Easy Operation: The offset design of the valve disc reduces operating torque, making it easier to actuate the valve using manual, electric, or pneumatic actuators. This feature improves valve control and reduces the risk of damage to the actuator and other system components.
Compact Design and Lighter Weight: Compared to other types of valves, triple offset butterfly valves typically have a more compact design and lighter weight, making them easier to install and integrate into piping systems. This can result in cost savings in terms of installation, transportation, and maintenance.
Overall, the combination of tight shut-off capabilities, durability, high-pressure resistance, ease of operation, and compact design makes triple offset butterfly valves an attractive choice for a wide range of industrial applications where reliable flow control is essential.
A wafer type triple set butterfly valve is a type of butterfly valve that is designed to regulate or control the flow of fluid in a pipeline. It consists of a disc which is mounted on a rod. When the valve is in the open position, the disc is turned parallel to the direction of flow, allowing fluid to pass through with minimal obstruction. When the valve is closed, the disc is turned perpendicular to the flow, blocking the passage of fluid.
The "wafer type" refers to the design of the valve, where it is sandwiched between flanges without the need for additional bolts or nuts. This design simplifies installation and reduces space requirements.
The "triple set" designation likely refers to the three sealing surfaces on the valve - one on the periphery of the disc and two on the valve body. This configuration ensures tight shut-off and prevents leakage when the valve is closed.
Overall, a wafer type triple set butterfly valve is often used in various industries for applications where precise control and reliable shut-off of fluids are required.
