Product Description – Wafer Mounted Butterfly Valve
One of the most versatile and widely used flow control valves in Indian industries.
Wafer Mounted Butterfly Valve is one of the most widely used flow control valves in Indian industries due to its compact design, cost-effectiveness, and ease of installation. These valves are designed to fit between two pipe flanges without the need for additional flange bolts, making them ideal for space-constrained piping systems. In India, wafer mounted butterfly valves are extensively used in water supply projects, fire fighting systems, HVAC plants, chemical processing units, power plants, sugar mills, cement plants, and general industrial pipelines where reliable shut-off and throttling performance is required.
Our wafer type butterfly valves are manufactured keeping Indian working conditions in mind, including fluctuating pressure, varying water quality, and demanding site environments commonly encountered in municipal water supply networks, industrial process plants, and infrastructure projects across the country. These valves are available in multiple body materials including Cast Iron (CI) for economical water applications, Ductile Iron (DI) for higher strength requirements, and Stainless Steel (SS 304/SS 316) for corrosion-resistant applications in chemical, pharma, and food processing plants.
The butterfly valve operates on a simple quarter-turn principle — a 90-degree rotation of the handle or gear operator moves the disc from fully open to fully closed position. This fast operation makes butterfly valves ideal for both isolation (on-off) and flow regulation (throttling) services. The resilient seat provides bubble-tight shut-off, ensuring zero leakage when the valve is fully closed. Compared to traditional gate valves and globe valves, wafer mounted butterfly valves offer significant advantages in terms of weight (up to 80% lighter), size (much shorter face-to-face), installation speed, and overall cost.
As a trusted valve supplier in Ahmedabad, Gujarat, Krishna Industries supplies wafer mounted butterfly valves to EPC contractors, municipal water boards, fire safety companies, HVAC installers, sugar mills, cement plants, and industrial buyers across India. Our valves are designed as per Indian and international standards (IS / BS / DIN) and undergo strict quality checks.

How a Butterfly Valve Works
Simple quarter-turn operation for fast, reliable flow control.
1
Quarter-Turn Operation
A 90-degree rotation of the handle or gear operator rotates the disc inside the valve body. Aligned with pipe = fully open; perpendicular = fully closed. Fast operation, typically under 5 seconds.
2
Disc Positioning
When fully open, the disc is parallel to the flow direction, offering minimal resistance and low pressure drop. When closing, the disc rotates perpendicular and presses against the resilient seat for tight shut-off.
3
Resilient Seat Sealing
The EPDM/NBR/Viton seat provides bubble-tight shut-off when the disc is in the closed position. The seat also protects the body and disc from the flowing media, extending service life.
4
Throttling Capability
Unlike gate valves (designed for on-off only), butterfly valves can be positioned at any angle between 0 and 90 degrees for flow regulation, making them suitable for both isolation and throttling services.

Wafer type is the most cost-effective butterfly valve design. No integral flanges means lower material, machining, and installation cost. Preferred for budget-conscious projects.
🛠
Wafer: Lightest Design
Lightest butterfly valve type — easy to handle, ship, and install. Ideal for large-diameter valves (12″+) where weight becomes a critical installation factor.
⏱
Wafer: Fastest Installation
Clamped between flanges — no independent flange bolts. Reduces installation time significantly. Most common style for water and fire systems in India.
🔄
Lug: End-of-Line Capability
Lug type has threaded lugs allowing dead-end service (end-of-line) installation where one side of the piping may be removed. Wafer type cannot do this.
🛡
Lug: Easier Pipe Removal
With lug type, downstream piping can be disconnected without disturbing the valve. Useful for maintenance access on branch lines and equipment connections.
✔
Choose Based on Application

Frequently Asked Questions (FAQ)
Quick answers to common queries about Wafer Mounted Butterfly Valves.
What is a wafer mounted butterfly valve?
A wafer mounted butterfly valve is a quarter-turn flow control valve designed to be installed between two pipe flanges without additional flange bolts. It consists of a circular disc mounted on a rotating shaft inside a short body. When the disc is parallel to the flow (0 degrees), the valve is fully open; when perpendicular (90 degrees), it is fully closed. The wafer-type design means the valve body has no integral flanges — it is clamped between the mating pipe flanges using stud bolts and nuts. This makes it the most compact, lightweight, and economical butterfly valve design, widely used in Indian water supply, fire fighting, HVAC, and industrial piping systems for both isolation (on-off) and flow regulation (throttling) services.
Is this valve suitable for Indian water supply projects?
Yes, wafer mounted butterfly valves are the most widely used valve type in Indian municipal water supply, irrigation, and infrastructure projects. The CI (Cast Iron) body with EPDM seat is the standard specification for water applications in India. Their compact size, lightweight design, fast quarter-turn operation, and economical pricing make them the preferred choice over gate valves for water distribution networks. The resilient EPDM seat provides bubble-tight shut-off, ensuring no water leakage. These valves are extensively used by municipal corporations, water boards, irrigation departments, and EPC contractors across all Indian states for water supply projects.
Can it be used for fire fighting systems?
Yes, these valves are commonly and extensively used in fire fighting pipelines across India. They are installed in fire hydrant systems, sprinkler networks, fire pump discharge lines, and combined fire protection systems. When manufactured as per required pressure ratings (PN10/PN16) and fire safety standards, wafer butterfly valves provide reliable shut-off and flow control for emergency fire protection applications. The fast quarter-turn operation allows rapid opening and closing, which is critical in fire emergency situations. EPDM seat material is standard for fire fighting water applications, and the wafer design allows easy integration into fire pump room piping layouts.
What is the difference between wafer and lug type butterfly valves?
Wafer type valves fit between flanges and are held in place by the flange bolts of the adjacent piping. They cannot be used for dead-end service (end-of-line). Lug type valves have threaded lugs (integral flange bosses) with their own independent bolting — they can be used for end-of-line service where one side of the piping may be removed for maintenance. Lug type is slightly more expensive and heavier but offers more installation flexibility. For most continuous pipeline applications in India (water, fire, HVAC), wafer type is the preferred and more economical choice. Lug type is selected when dead-end service or independent pipe removal capability is required.
What operating options are available?
Wafer mounted butterfly valves are available with two primary operating options. Lever operated (also called handle operated) is standard for smaller sizes, typically up to 6″ (DN150). The lever provides a visible indication of valve position and requires no tools for operation. Gear operated is used for larger sizes, typically 8″ (DN200) and above, where the torque required to operate the valve exceeds what a manual lever can comfortably provide. The gear operator multiplies the input force, allowing smooth operation of large-diameter valves. Both lever and gear operated valves can be further equipped with pneumatic, electric, or electro-hydraulic actuators for automated or remote control applications on request.
Are these valves suitable for throttling applications?
Yes, butterfly valves can be used for throttling as well as on-off service. Unlike gate valves (designed only for fully open or fully closed position), butterfly valves can be positioned at any angle between 0 and 90 degrees to regulate flow rate. However, for precise throttling applications where accurate flow control is required over a wide range, the disc position between 10 degrees and 60 degrees from closed provides the most linear and controllable flow characteristic. For throttling in aggressive media or at high velocities, the disc and seat may experience accelerated wear. In such cases, a more specialized control valve may be recommended. For general industrial flow regulation in water, HVAC, and utility systems, wafer butterfly valves provide excellent throttling performance.
What seat materials are commonly used?
Three seat materials are most commonly used in Indian butterfly valve applications: EPDM (Ethylene Propylene Diene Monomer) is the most common and is used for water, air, and neutral fluids. It offers excellent water resistance, long life, and is the standard choice for Indian municipal water and fire fighting applications. NBR (Nitrile Butadiene Rubber) is used for petroleum products, oil, diesel, and fuel applications where EPDM would swell or degrade. Viton (Fluorocarbon rubber) is used for aggressive chemicals, acids, solvents, and high-temperature applications where superior chemical resistance is required. The seat is typically interchangeable, allowing field replacement to adapt the valve to different media without changing the entire valve body.
What maintenance is required?
Minimal maintenance is required for wafer mounted butterfly valves when operated under recommended conditions. Routine maintenance typically involves periodic visual inspection of the external body for corrosion or damage, checking that the disc rotates freely and smoothly through the full 0-90 degree range, verifying that the lever or gear operator is functioning properly, and inspecting flange bolting for tightness during scheduled plant shutdowns. The resilient seat and disc are the primary wear components and may need replacement after extended service in abrasive or aggressive media. The wafer-type design allows the valve body to remain in the pipeline while the seat and disc are replaced, significantly reducing maintenance downtime and cost.
Can these valves handle bi-directional flow?
Yes, wafer mounted butterfly valves are designed for bi-directional flow — they can be installed with flow in either direction without affecting performance. The symmetrical body design and the resilient seat seal equally well from both directions. This bi-directional capability provides significant flexibility in piping design, allowing the valve to be installed without worrying about flow direction markings (though most valves do have an arrow cast into the body indicating the preferred orientation). This is particularly advantageous in ring main systems, fire fighting loop layouts, and complex piping networks where flow direction may vary or is difficult to determine at the design stage.
Do you provide test certificates?
Yes, manufacturer test certificates can be provided as per customer requirement. Standard documentation includes GST invoice and material declaration. On request, we can provide: material test certificates (MTC) as per EN 10204 Type 3.1 with chemical composition and mechanical properties, hydrostatic shell test reports showing the valve was tested at 1.5x rated pressure, seat leakage test reports confirming bubble-tight shut-off performance, and dimensional inspection certificates. These documents are essential for EPC project documentation, third-party inspection requirements, government tender compliance (especially Jal Jeevan Mission and AMRUT water projects), and quality management system records. Please specify your documentation requirements at the time of order placement.
