Triple Eccentric Butterfly Valve

Triple Eccentric Butterfly Valve Manufacturer & Supplier in India

A Triple Eccentric Butterfly Valve, also known as a Triple Offset Butterfly Valve,
is a high-performance industrial valve designed for zero-leakage shut-off, long service life,
and reliable operation under high pressure and high temperature conditions.
In demanding Indian industries such as power plants, refineries, steel plants,
oil & gas, petrochemicals, fertilizers, and process industries, triple eccentric butterfly valves
are increasingly preferred over conventional gate valves and globe valves.

Krishna Industries, based in Ahmedabad, Gujarat, India,
is a trusted supplier of triple eccentric butterfly valves to customers across India.
We supply valves suitable for Indian operating conditions, Indian standards,
and Indian project requirements, ensuring cost-effective solutions without compromising
on quality or performance.

This product page provides detailed technical information, applications, advantages,
specifications, materials, testing standards, and FAQs to help Indian buyers,
consultants, contractors, and maintenance engineers make an informed decision.

What is a Triple Eccentric Butterfly Valve?

A Triple Eccentric Butterfly Valve is a metal-seated butterfly valve
designed with three distinct offsets (eccentricities) between the shaft, disc,
and sealing surface. These three offsets eliminate friction between the seat and disc
during operation, ensuring a true cam-action closing mechanism.

Unlike concentric or double eccentric butterfly valves,
the triple eccentric design ensures that the sealing surfaces
only come in contact at the final moment of closure.
This prevents wear, galling, and deformation of sealing surfaces,
making the valve suitable for high temperature and high pressure services.

In Indian industries where leakage control, fire safety,
and long operational life are critical,
triple eccentric butterfly valves have become a preferred choice.

However, among these, the Triple Eccentric Butterfly Valve
offers superior sealing performance, longer life,
and lower maintenance costs for critical Indian industrial applications.

Why Triple Eccentric Butterfly Valves are Preferred in India

Indian industries operate under harsh conditions such as fluctuating temperatures,
dusty environments, corrosive media, and continuous duty cycles.
Triple eccentric butterfly valves are designed to handle these challenges effectively.

• Suitable for high temperature steam lines
• Excellent for high pressure fluid systems
• Reliable shut-off in corrosive and abrasive media
• Low torque operation reduces actuator size
• Long service life reduces replacement cost

For Indian buyers looking for durability, safety, and long-term value,
triple eccentric butterfly valves are a practical investment.

Design Principle of Triple Eccentric Butterfly Valve

First Eccentricity

The shaft is offset from the centreline of the disc,
reducing friction between disc and seat during opening.

Second Eccentricity

The shaft is offset from the pipeline centreline,
allowing the disc to move away from the seat quickly.

Third Eccentricity

The sealing surface is inclined at an angle,
ensuring true metal-to-metal sealing with zero rubbing.

These three offsets together create a cam-action movement
that ensures tight shut-off with minimal wear.
