INTRODUCTION

In modern industrial flow control systems, the demand for reliable, high-performance, and long-life valves has increased significantly. Industries such as water treatment, power generation, chemicals, oil & gas, HVAC, fire protection, sugar plants, cement plants, steel plants, and large infrastructure projects require valves that can withstand high pressure, high temperature, frequent operation, and demanding service conditions. The Double Eccentric High Performance Butterfly Valve is specifically designed to meet these requirements with superior sealing performance, reduced operating torque, extended service life, and dependable shut-off.

Krishna Industries, based in Ahmedabad, Gujarat, India, is a trusted manufacturer and supplier of industrial valves catering to Indian buyers across all major industrial regions. With deep technical knowledge, manufacturing capability, and a strong supply network, Krishna Industries supplies Double Eccentric High Performance Butterfly Valves suitable for demanding Indian industrial applications. Our focus is on durability, precision engineering, compliance with Indian and international standards, and cost-effective solutions for bulk buyers, EPC contractors, government projects, OEMs, and industrial end users.

The Double Eccentric High Performance Butterfly Valve, also known as a double offset butterfly valve, is an advanced evolution of the conventional concentric and single eccentric butterfly valve. In this design, the disc is offset from the valve seat in two directions: first from the shaft centerline and second from the body centerline. This double offset geometry ensures that the disc only contacts the seat during the final stage of closing, minimizing friction, wear, and operating torque. As a result, the valve provides bubble-tight shut-off, longer seat life, and reliable performance even in high-pressure and high-temperature conditions.

This valve category is often selected as an alternative to gate valves, globe valves, and plug valves due to its compact design, lighter weight, faster operation, and lower maintenance requirements. The Double Eccentric High Performance Butterfly Valve is widely used where tight shut-off, frequent operation, and long service life are critical. Related products frequently used alongside this valve include concentric butterfly valves, triple offset butterfly valves, resilient seated butterfly valves, metal seated butterfly valves, wafer type butterfly valves, lug type butterfly valves, and flanged butterfly valves.

PRODUCT OVERVIEW

The Double Eccentric High Performance Butterfly Valve is designed to provide excellent sealing performance with minimal wear. The double offset shaft arrangement reduces seat abrasion and ensures smooth opening and closing. This design significantly improves valve life compared to conventional butterfly valves.

The valve is suitable for both on-off and throttling services, although it is primarily recommended for tight shut-off applications. It is available in wafer type, lug type, and double flanged configurations depending on installation requirements. The valve can be operated manually using a lever or gearbox, or automated using electric or pneumatic actuators.

Krishna Industries supplies these valves in a wide range of sizes and pressure ratings suitable for Indian industrial standards. Each valve is manufactured with strict quality checks to ensure dimensional accuracy, sealing integrity, and operational reliability.

KEY DESIGN FEATURES

Double Offset Design
The double eccentric geometry ensures that the disc moves away from the seat immediately during opening. This reduces friction between the disc and seat, minimizing wear and tear. The result is longer service life and consistent sealing performance over thousands of cycles.

High Performance Seat
The seat design offers excellent sealing even under high pressure and temperature conditions. Depending on application requirements, soft seat or metal-backed seat options can be provided to suit water, steam, oil, gas, and chemical services.

Low Operating Torque
Due to reduced friction and optimized disc geometry, the valve requires lower operating torque compared to concentric butterfly valves. This makes manual operation easier and reduces actuator size and cost for automated systems.

Compact and Lightweight
Compared to gate valves and globe valves of similar size, the Double Eccentric High Performance Butterfly Valve is compact and lightweight. This reduces installation space requirements, foundation load, and overall project cost.

Bi-Directional Sealing
The valve is designed to provide effective sealing in both flow directions, making it suitable for flexible piping layouts commonly found in Indian industrial plants.

Wide Range of Sizes
The valve is available in small, medium, and large diameters to suit various pipeline requirements across industries.
