Triple Eccentric Wafer Type Butterfly Valve Metal & Soft Seated

Description

TRIPLE ECCENTRIC WAFER TYPE BUTTERFLY VALVE – METAL & SOFT SEATED
Manufactured & Supplied by Krishna Industries, Ahmedabad, Gujarat, India

INTRODUCTION

In modern industrial flow control systems, the demand for reliable shut-off, zero leakage, long service life, and minimal maintenance has increased significantly. Industries such as power plants, refineries, steel plants, chemical processing units, water treatment facilities, cement plants, and large infrastructure projects require valves that can withstand high pressure, high temperature, corrosive media, and continuous operation. To meet these demanding conditions, the Triple Eccentric Wafer Type Butterfly Valve has emerged as one of the most advanced and dependable valve designs available in the Indian industrial market.

Krishna Industries, based in Ahmedabad, Gujarat, India, offers high-quality Triple Eccentric Wafer Type Butterfly Valves in both metal seated and soft seated designs, specifically engineered to meet Indian operating conditions, Indian standards, and Indian buyer expectations. With strong technical understanding, reliable sourcing, and strict quality control, Krishna Industries positions itself as a trusted supplier for industries across India seeking performance-oriented butterfly valves at competitive prices.

Unlike concentric or double eccentric butterfly valves, the triple eccentric design eliminates rubbing between the disc and seat during operation. This design innovation ensures extended service life, tight shut-off, and consistent performance even in severe service applications. These valves are widely used as isolation valves in pipelines carrying steam, thermal oil, gas, water, chemicals, hydrocarbons, and other process fluids.

The Triple Eccentric Wafer Type Butterfly Valve is often compared alongside high-performance butterfly valves, metal seated butterfly valves, soft seated butterfly valves, wafer type butterfly valves, and zero leakage isolation valves. These related valve categories highlight the versatility and technical superiority of triple eccentric designs in industrial flow control systems.

Krishna Industries focuses on supplying these valves to Indian buyers including EPC contractors, project consultants, industrial plants, maintenance departments, OEMs, dealers, and bulk traders who require dependable valves with assured quality and after-sales support within India.

PRODUCT OVERVIEW

The Triple Eccentric Wafer Type Butterfly Valve is designed with three distinct offsets between the shaft, disc, and seat geometry. This triple offset design ensures that the disc only contacts the seat at the final moment of closure, achieving a cam-like action that provides tight shut-off without frictional wear.

The wafer type construction allows easy installation between flanges, reduces weight, and saves space compared to lug or double-flanged valves. This makes it an ideal solution for large diameter pipelines where compact design and cost efficiency are important.

Krishna Industries supplies both metal seated and soft seated variants to suit different service conditions. Metal seated valves are preferred for high-temperature, high-pressure, and abrasive services, while soft seated valves are ideal for applications requiring bubble-tight shut-off at relatively lower temperatures.

DESIGN FEATURES AND ENGINEERING

Triple Eccentric Design
The triple eccentric geometry consists of three offsets: the shaft is offset from the disc center, the shaft is offset from the pipeline centerline, and the sealing surface is inclined. This design eliminates seat wear and ensures smooth operation.

Wafer Type Body Construction
The wafer type body is compact, lightweight, and suitable for installation between standard flanges. It reduces installation cost and is especially suitable for space-constrained piping systems.

Metal Seated Option
Metal seated triple eccentric butterfly valves are designed for high-temperature and high-pressure services. The seat is typically made from stainless steel or hard-faced alloy, ensuring durability and resistance to thermal expansion.

Soft Seated Option
Soft seated versions use materials such as PTFE, reinforced PTFE, or elastomers depending on application requirements. These valves provide excellent sealing performance for water, air, and low-temperature process media.

Bi-Directional Sealing
The valve design allows tight sealing in both flow directions, making it suitable for complex piping layouts.

Low Operating Torque
Due to the friction-free sealing mechanism, operating torque is significantly lower than conventional butterfly valves, reducing actuator size and operating cost.

Fire Safe Construction
Metal seated variants can be supplied with fire-safe design suitable for critical applications.
