Product Overview

Flanged Butterfly Valves are high-performance quarter-turn valves engineered for reliable shut-off and flow regulation in medium to large diameter pipelines. These valves are designed with integrally cast flanges conforming to international standards such as ANSI, DIN, BS, and IS specifications, enabling secure bolted connections to pipeline flanges.

At Krishna Industries, we supply precision-manufactured flanged butterfly valves suitable for water treatment plants, HVAC systems, chemical processing units, fire fighting lines, power plants, irrigation systems, marine installations, and general industrial piping networks.

Our valves are engineered for durability, minimal pressure drop, bubble-tight sealing, and long service life under demanding industrial conditions.

Long Introduction – Industrial Significance & Application Scope

In modern industrial infrastructure, efficient fluid control is critical for operational safety, process stability, and energy efficiency. Among various flow control devices, the flanged butterfly valve has emerged as a preferred solution for large-diameter pipeline systems due to its compact design, lightweight structure, cost efficiency, and quick actuation.

Unlike conventional gate or globe valves, flanged butterfly valves operate using a rotating disc mounted on a shaft. When rotated 90 degrees, the disc moves from fully open to fully closed position, enabling rapid shut-off. The flanged body construction allows direct bolting between pipeline flanges without additional lug or wafer-style retention hardware.

These valves are widely used in systems where space optimization, low torque operation, and quick maintenance are priorities. In comparison to a Wafer Butterfly Valve, the flanged design provides enhanced structural rigidity and is suitable for high-pressure installations. Compared to a Lug Type Butterfly Valve, the flanged type ensures stronger axial retention and is preferred in permanent installations.

In many industrial applications, flanged butterfly valves are integrated alongside Gate Valves, Globe Valves, and Check Valves to create complete flow management systems. They are especially suitable for isolation duty, throttling service, and bi-directional flow control.

Krishna Industries ensures that every flanged butterfly valve supplied is dimensionally accurate, hydrostatically tested, and compliant with relevant industrial standards. As a Supplier, Wholesaler, Exporter, Distributor and Trader from Ahmedabad, Gujarat, India, we maintain strict quality control processes before dispatch.
