Introduction

In modern Indian industrial infrastructure, flow control equipment plays a decisive role in ensuring safety, efficiency, and long-term operational reliability. Among the most widely adopted flow control solutions across water supply, effluent treatment, HVAC, chemical processing, power plants, and general industrial pipelines is the Rubber Lined Wafer Type Double Flange Butterfly Valve. This valve design has become a preferred choice for Indian engineers, contractors, EPC companies, municipal corporations, and industrial maintenance teams because it offers an optimal balance of durability, tight shut-off, cost efficiency, and ease of installation.

The Rubber Lined Wafer Type Double Flange Butterfly Valve is engineered to regulate or isolate the flow of liquids and gases in pipelines where consistent sealing, corrosion resistance, and compact installation are critical. Unlike conventional gate valves or globe valves, butterfly valves use a rotating disc mechanism, which allows quick operation with minimal torque and reduced space requirements. When combined with a precision-molded rubber liner and double flange mounting arrangement, the valve delivers superior leak-proof performance even in demanding Indian operating conditions such as fluctuating pressures, variable water quality, and high ambient temperatures.

At Krishna Industries, Ahmedabad, Gujarat, India, we specialize in supplying high-quality Rubber Lined Wafer Type Double Flange Butterfly Valves tailored for Indian industrial and infrastructure requirements. With years of experience as a trusted valve supplier and industrial solutions partner, Krishna Industries understands the exact needs of Indian buyers, whether they are sourcing valves for municipal water projects, factory pipelines, commercial buildings, or OEM integration. Our valves are manufactured and supplied with strict quality control, ensuring compatibility with Indian standards, Indian piping practices, and Indian operating environments.

This product is closely associated with several related flow control components such as cast iron butterfly valves, rubber seated butterfly valves, wafer type butterfly valves, double flanged butterfly valves, and industrial isolation valves. These related valve categories often work together within the same piping system, and the Rubber Lined Wafer Type Double Flange Butterfly Valve stands out as a versatile and reliable solution across multiple applications.

Understanding the Rubber Lined Wafer Type Double Flange Butterfly Valve

A Rubber Lined Wafer Type Double Flange Butterfly Valve is designed with a circular disc mounted on a central shaft. The disc rotates by 90 degrees to open or close the flow path. The inner body of the valve is lined with an elastomeric rubber liner that provides excellent sealing, corrosion resistance, and protection to the valve body. The wafer-type design allows the valve to be installed between two pipe flanges, while the double flange compatibility ensures secure alignment, proper sealing, and uniform load distribution across the pipeline.

The rubber liner plays a critical role in ensuring bubble-tight shut-off. It acts as both a sealing element and a protective barrier between the process media and the metallic valve body. This makes the valve especially suitable for water, wastewater, slurry, mild chemicals, and air applications commonly encountered in Indian industries and municipal systems.

The double flange installation configuration ensures that the valve remains stable even in larger diameters and higher flow velocities. It reduces the risk of misalignment, leakage, or vibration-related issues that can occur in long pipeline runs. This is particularly important in Indian infrastructure projects where pipelines may experience uneven loads, thermal expansion, or external stress.

Construction and Design Features

The Rubber Lined Wafer Type Double Flange Butterfly Valve supplied by Krishna Industries is designed with robustness and service life in mind. The valve body is typically manufactured from high-grade cast iron or ductile iron suitable for Indian pressure and temperature conditions. The internal rubber lining is bonded or molded with precision to ensure uniform thickness, strong adhesion, and long-term performance.

The disc is engineered for smooth flow characteristics and minimal pressure drop. It is carefully machined and balanced to reduce operating torque and wear. The shaft is supported by suitable bearings or bushings to ensure smooth rotation and long operational life even with frequent operation.

The valve design allows for manual operation using lever or gearbox depending on valve size and application requirements. The compact face-to-face dimensions make it easy to install in confined spaces, which is often a requirement in Indian industrial plants and retrofitting projects.

Advantages for Indian Buyers

Indian buyers prioritize reliability, value for money, ease of maintenance, and availability of spares. The Rubber Lined Wafer Type Double Flange Butterfly Valve addresses all these priorities effectively.

One of the key advantages is cost efficiency. Compared to gate valves or ball valves of similar size, butterfly valves are more economical while still providing dependable shut-off and flow control. The rubber lining reduces corrosion-related failures, extending service life and lowering maintenance costs.

Another major advantage is ease of installation. The wafer-type design allows quick fitting between flanges without extensive pipeline modifications. This saves installation time and labor costs, which is especially beneficial for Indian contractors working under tight project schedules.

The rubber liner also ensures compatibility with varying water qualities found across different regions of India, including hard water, treated water, raw water, and wastewater. This makes the valve suitable for use in municipal water supply systems, sewage treatment plants, and industrial effluent pipelines.

Applications in Indian Industries

The Rubber Lined Wafer Type Double Flange Butterfly Valve is widely used across multiple sectors in India.

In water supply and distribution systems, these valves are used for isolation and regulation in pumping stations, overhead tanks, underground pipelines, and treatment plants. Municipal corporations and private water projects rely on these valves for dependable performance and long service life.

In wastewater and sewage treatment plants, the rubber lining provides resistance against corrosive and abrasive media, making the valve suitable for sludge lines, effluent pipelines, and recycling systems.

In HVAC systems, these valves are used in chilled water and cooling water circuits to control flow efficiently while maintaining compact installation.

In industrial plants such as chemical factories, textile units, food processing plants, paper mills, and power plants, the valve is used wherever moderate pressure and temperature conditions exist, and where reliable isolation is required.

In irrigation and agricultural water management systems, these valves help control water flow in canals, pump houses, and distribution networks.
