In industries and municipal water systems where space, efficiency, and budget matter, wafer type butterfly valves have become a go-to solution. Compact, reliable, and easy to install, they offer a simple yet powerful way to control flow in pipelines carrying water, chemicals, air, or gas.
In this blog, we’ll break down everything you need to know about wafer type butterfly valves, their working principle, features, and applications. We’ll also explain how they compare to other valves like sluice valves, air valves, and pressure reducing valves.
🔧 What Is a Wafer Type Butterfly Valve?
A wafer type butterfly valve is a quarter-turn valve designed to regulate or isolate flow. The valve consists of a metal disc (the “butterfly”) mounted on a rotating shaft. When the handle or actuator turns the shaft 90 degrees, the disc opens or closes the valve to control the fluid flow.
The “wafer” design refers to how the valve is mounted. It is sandwiched between two pipe flanges, making it more compact and lightweight than other flanged valve types.
✅ Key Features of Wafer Type Butterfly Valves
Wafer butterfly valves are widely used due to their cost-efficiency and space-saving design. Below are the standout features that make them popular:
1. Slim Profile & Lightweight
Wafer valves are compact, making them ideal for tight spaces and easy installation. Their lightweight design also reduces load on the piping system.
2. Quick Operation
These valves can be operated manually or automatically and require only a quarter-turn to fully open or close, saving time and effort.
3. Leak-Proof Sealing
Modern wafer butterfly valves come with resilient elastomer seats that provide a bubble-tight seal, even in low-pressure systems.
4. Corrosion Resistance
Valves from reliable manufacturers like resilientgatevalve are coated with epoxy or powder coatings, which help prevent corrosion and ensure longer service life.
5. Low Maintenance
Due to fewer moving parts, wafer butterfly valves require minimal servicing and have a longer operational lifespan.
🛠 Where Are Wafer Type Butterfly Valves Used?
These valves are used across various sectors due to their adaptability. Common applications include:
- 🚰 Municipal Water Supply Systems
- 🏭 Industrial Flow Control (chemicals, oils, gas)
- 🚜 Irrigation Systems
- 🔥 Fire Fighting Networks
- 💧 Sewage & Wastewater Management
- 🌾 Agricultural Water Lines
For municipal projects, engineers often prefer resilient seated sluice valves and wafer butterfly valves together for different pressure zones and flow control.
🆚 Wafer Butterfly Valve vs. Other Flow Control Valves
To choose the right valve for your project, it’s important to understand how wafer type butterfly valves compare with other types:
🔹 Resilient Seated Sluice Valve
These are gate-type valves that provide full bore flow and tight shut-off. They are better for on-off applications in underground water systems.
Use When: You need full flow or zero obstruction.
🔹 Metal Seated Sluice Valve
Ideal for dirty water or high-temperature fluids, where rubber seats may wear out. These valves are heavy-duty but not suitable for tight spaces.
Use When: You have high-pressure, abrasive fluids.
🔹 Air Valves Single and Double
Not used for stopping water, but for removing trapped air in the line. They ensure efficient flow and prevent water hammer.
Use When: You need air release at pipeline high points.
🔹 Non Return Valve (NRV)
Also called check valves, NRVs allow flow in one direction and prevent backflow. Often installed downstream of pumps.
Use When: You need to prevent reverse flow.
🔹 Pressure Reducing Valve
These valves reduce incoming high pressure to a safe level. Ideal for urban water supply or drip irrigation.
Use When: You need controlled pressure zones.
In Summary:
For compact spaces and quick shut-off, wafer butterfly valves are best. But for buried lines or flow regulation, sluice valves or PRVs may be more suitable.
