Specialty Valve stands out as a dependable Double Offset Butterfly Valve Manufacturers in India , celebrated for its unwavering commitment to quality.
The double eccentric butterfly valve, an advanced iteration of its single eccentric counterpart, boasts dual offsets - one in the shaft and another in the center of the disc, enhancing sealing performance, minimizing friction, and prolonging the valve's lifespan. Primarily designed for controlling fluid or gas flow within pipelines, this valve finds versatile applications across industries.
Overview
The term "offset" in valve context denotes an offset or deviation from the center. In a double offset butterfly valve, having two offsets - one in the shaft and another in the center of the disc - contributes to improved sealing and operational efficiency.
How a Double Offset Butterfly Valve Works
Basic Design: Like all butterfly valves, a double offset butterfly valve consists of a circular body with a disc (also known as a "butterfly") mounted inside. The disc is connected to a stem that extends out of the valve body.
Offset Axes: The "double offset" design refers to the fact that both the shaft and the center of the disc are offset from the centerline of the valve. This offset configuration helps reduce wear and friction during operation.
Sealing Mechanism: The sealing of a double offset butterfly valve is typically achieved through a resilient seat material, such as rubber or PTFE, which forms a tight seal against the disc when the valve is closed. The offset design allows the disc to make a more perpendicular contact with the seat, improving sealing performance and reducing the likelihood of leakage.
Operation: When the valve is in the fully closed position, the disc forms a seal against the valve seat, blocking the flow of fluid through the pipeline. To open the valve, the stem is rotated, causing the disc to pivot away from the seat, allowing fluid to flow through the valve. The double eccentric design ensures that the disc moves smoothly and efficiently without excessive friction.
Control: Double offset butterfly valves can be operated manually, pneumatically, or electrically, depending on the specific application requirements.
