Flange type Butterfly Valve

A Flange Type Butterfly Valve is a type of butterfly valve designed with flanged ends for secure bolted connections between pipeline flanges. It consists of a circular disc mounted on a rotating shaft, which turns 90° to open or close the flow. When the disc is parallel to the flow, the valve is fully open, offering minimal resistance; when perpendicular, it provides a tight shut-off.

Flange type butterfly valves are widely used in water supply, HVAC, chemical, and industrial pipelines where secure connections, easy installation, and reliable sealing are required. Their robust construction, compact design, and quick quarter-turn operation make them ideal for large-diameter pipelines and high-flow systems. They are available in various materials and sizes to suit different pressure, temperature, and application requirements.

Features

Flanged End Connections – Provides secure, easy, and leak-proof installation between pipeline flanges.
Quick Quarter-Turn Operation – Allows fast opening and closing of the valve.
Compact and Lightweight Design – Saves space and reduces installation weight.
Reliable Shut-Off – Ensures tight sealing to prevent leakage.
Versatile Applications – Suitable for water, oil, gas, chemical, and HVAC systems.
Durable Construction – Made from high-quality materials for long-term performance and low maintenance.
