DOUBLE OFFSET BUTTERFLY VALVES

Our BORE UD model double eccentric butterfly valves are a type of industrial valve designed for efficient fluid flow control in pipelines. The “double offset” refers to two distinct offsets in the valve’s design, contributing to enhanced performance and durability. The first offset occurs at the shaft, and the second offset is at the centerline of the disc.

These valves typically feature a construction with materials like cast iron, ductile iron, carbon steel, stainless steel, or other alloys, depending on the specific application. The disc, responsible for controlling flow, is often made of metal or composite materials, providing strength and corrosion resistance.

Operation is based on a quarter-turn principle, allowing quick and easy opening or closing. Double offset butterfly valves can be manually operated or automated using pneumatic, electric, or hydraulic actuators for remote and precise control. The sealing mechanism involves a resilient seat, commonly made of materials like EPDM, Nitrile, or PTFE, ensuring a tight seal against the disc and minimizing leakage. Key performance features include low torque operation, reducing the energy required for valve operation, and high performance in terms of reliable sealing, low pressure drop, and suitability for various applications. These valves find application across industries such as water treatment, chemical processing, oil and gas, power generation, and HVAC systems. They are versatile, serving both flow control and isolation duties with a balance between precision control and effective shut-off.

Advantages of double offset butterfly valves include reduced wear due to minimized friction and an extended service life, making them a cost-effective choice for fluid control in industrial settings.
