Butterfly Valves

Description

Butterfly Valves Manufacturer & Supplier in Ahmedabad, Gujarat, India – Krishna Industries

Introduction to Butterfly Valves

Butterfly valves are one of the most widely used flow control devices in modern piping systems due to their compact design, cost efficiency, and reliable shut-off capability. A butterfly valve works by rotating a disc inside the valve body to regulate, throttle, or isolate the flow of liquids, gases, and semi-solids. Because of their simple construction and quick quarter-turn operation, butterfly valves are extensively used across industries such as water treatment, HVAC, fire protection, chemicals, pharmaceuticals, power plants, food processing, irrigation, and general industrial utilities.

Krishna Industries, based in Ahmedabad, Gujarat, India, is a trusted manufacturer and supplier of high-quality butterfly valves designed specifically for Indian industrial requirements. Our butterfly valves are engineered to deliver consistent performance, long service life, and low maintenance even under demanding operating conditions. We focus 100% on Indian buyers, offering competitive pricing, reliable lead times, and local technical support.

As an established butterfly valve supplier in Ahmedabad, Krishna Industries manufactures and supplies a wide range of concentric butterfly valves, double offset butterfly valves, triple offset butterfly valves, wafer type butterfly valves, lug type butterfly valves, and flanged butterfly valves. Our valves are available in cast iron, ductile iron, carbon steel, stainless steel, and special alloy constructions, suitable for a variety of pressure ratings and temperature ranges.

What is a Butterfly Valve and How It Works

A butterfly valve consists of four main components: the valve body, disc, stem, and seat. The disc is mounted on a rotating shaft. When the handle, gearbox, or actuator turns the stem by 90 degrees, the disc rotates from a fully closed position to a fully open position. In the open position, the disc is parallel to the flow, allowing fluid to pass with minimal pressure drop. In the closed position, the disc is perpendicular to the flow, effectively stopping it.

The sealing between the disc and the seat ensures tight shut-off. Depending on the application, butterfly valves can be used for on-off service as well as throttling service. Their lightweight design and compact face-to-face dimensions make them ideal for installations where space and weight are critical factors.

Types of Butterfly Valves Offered by Krishna Industries

Krishna Industries supplies a comprehensive range of butterfly valves to meet diverse industrial needs across India.

Wafer Type Butterfly Valves
Wafer type butterfly valves are designed to fit between two pipeline flanges. They are held in place by bolts passing through the flanges. These valves are compact, lightweight, and economical, making them a popular choice for water supply, HVAC, fire fighting, and general industrial services.

Lug Type Butterfly Valves
Lug type butterfly valves have threaded inserts or lugs around the valve body. This design allows the valve to be installed with bolts from one side only, enabling dead-end service. Lug type butterfly valves are suitable where pipeline isolation is required without shutting down the entire system.

Flanged Butterfly Valves
Flanged butterfly valves have integral flanges on both sides of the valve body. These are robust valves used in higher pressure applications and larger pipe sizes. They provide strong structural support and are commonly used in power plants, water treatment plants, and heavy industrial pipelines.

Concentric Butterfly Valves
In concentric butterfly valves, the stem passes through the centerline of the disc and the seat is elastomer-lined. These valves are widely used for low to medium pressure applications such as water, air, and non-corrosive fluids.

Double Offset Butterfly Valves
Double offset butterfly valves have an offset stem and disc, reducing friction between the disc and seat during operation. This design improves sealing performance and extends valve life. They are suitable for higher pressure and temperature applications.

Triple Offset Butterfly Valves
Triple offset butterfly valves feature three offsets that eliminate rubbing between the disc and seat, providing a metal-to-metal seal. These valves are ideal for high-temperature, high-pressure, and critical applications such as steam, oil, and gas services.
