Triple Eccentric Wafer Butterfly Valve

Triple Eccentric Wafer Butterfly Valve – Industrial Grade Valve Supplier in India

Overview

The Triple Eccentric Wafer Butterfly Valve is a high-performance isolation valve designed for
demanding industrial applications where tight shut-off, long service life, and minimal maintenance are critical.
Unlike conventional concentric or double eccentric butterfly valves, the triple eccentric design eliminates seat
wear during operation, making it ideal for high-temperature, high-pressure, and corrosive service conditions.

Krishna Industries, based in Ahmedabad, Gujarat, India, supplies premium quality
triple eccentric wafer butterfly valves to customers across India for applications in
power plants, oil & gas, chemical processing, refineries, steel plants, water treatment facilities, and large
industrial pipelines.

Long Introduction – Triple Eccentric Wafer Butterfly Valve

In modern Indian industries, valve performance directly impacts plant efficiency, safety, and operational cost.
As process conditions become more severe, traditional isolation valves often fail to deliver consistent sealing
and durability. This is where the triple eccentric wafer butterfly valve plays a critical role.

A triple eccentric butterfly valve is engineered with three distinct offsets:
the shaft offset from the seat centerline, the shaft offset from the pipe centerline,
and a conical sealing geometry. This advanced design ensures that the disc does not rub
against the seat during opening or closing, drastically reducing friction and wear.

Compared to double eccentric butterfly valves, high performance butterfly valves,
metal seated butterfly valves, and resilient seated butterfly valves,
the triple eccentric valve offers superior shut-off performance and extended service life.
This makes it the preferred choice for critical isolation duties in Indian industrial plants.

In wafer type construction, the valve is installed between two pipe flanges using studs and bolts.
The wafer design reduces weight, saves space, and lowers installation cost while maintaining structural integrity.
For Indian buyers looking to optimize piping layouts without compromising reliability, the
triple eccentric wafer butterfly valve is a practical and economical solution.

At Krishna Industries, we understand Indian operating conditions – fluctuating temperatures,
variable pressure, inconsistent water quality, aggressive chemicals, and continuous duty cycles.
Our supplied triple eccentric wafer butterfly valves are sourced and manufactured to meet
international standards while remaining cost-effective for Indian industries.

Key Design Features

• Triple offset geometry for zero rubbing during operation
• Metal-to-metal sealing for tight shut-off
• Wafer type body for compact installation
• Low operating torque
• Fire-safe and fugitive emission compliant options
• Suitable for bi-directional flow

Construction Details

Body

The valve body is available in Cast Iron (CI), Cast Steel (WCB),
Carbon Steel, Stainless Steel (CF8 / CF8M), and
special alloy materials as per application requirement. Wafer design allows easy integration
into existing pipelines with minimum modification.

Disc

The disc is precision machined and designed to provide excellent sealing with minimal torque.
Disc materials include SS304, SS316, duplex steel, and other alloys for corrosive or high-temperature services.

Seat

Triple eccentric valves typically use a metal laminated seat or
solid metal seat. This allows operation in temperatures far beyond the limits
of soft-seated valves and ensures long-term sealing reliability.

Stem / Shaft

High-strength stainless steel shafts ensure accurate disc positioning and resistance to bending under pressure.
Anti-blowout design is standard for safety.

Operating Pressure & Temperature

• Pressure Class: PN10, PN16, PN25, PN40, Class 150, Class 300
• Temperature Range: Up to 550°C (depending on seat and material)

This wide operating range makes the triple eccentric wafer butterfly valve suitable for
steam lines, thermal oil systems, high-pressure gas pipelines, and chemical processing units in India.

Actuation Options

• Manual Lever Operated
• Gear Operated (Worm Gear)
• Pneumatic Actuator
• Electric Actuator
• Hydraulic Actuator

Krishna Industries can supply valves with factory-mounted actuators as per customer specifications,
including ON/OFF and modulating duty.

Applicable Standards

• Design: API 609, ASME B16.34
• Face to Face: API 609 / ISO 5752
• Flange Compatibility: ASME B16.5, EN 1092-1, IS Standards
• Testing: API 598 / ISO 5208
• Fire Safe: API 607 (on request)

Industries & Applications in India

• Oil & Gas Refineries
• Petrochemical Plants
• Chemical & Fertilizer Industries
• Power Plants (Thermal & Combined Cycle)
• Steel & Metal Processing Plants
• Water Treatment & Desalination Plants
• Cement Plants
• Pulp & Paper Industries

Indian EPC contractors and project consultants prefer triple eccentric butterfly valves
for critical isolation where zero leakage and long service life are mandatory.

Why Choose Triple Eccentric Wafer Butterfly Valve Over Other Valves?

Compared to gate valves, globe valves, and conventional butterfly valves, the triple eccentric design
offers significant advantages:

• Lower weight and compact size
• Faster operation
• Minimal maintenance
• Superior sealing performance
• Lower life-cycle cost

For Indian plants operating continuously, these benefits translate into reduced downtime
and lower operational expenses.
