Wafer Type Electric Actuated Butterfly Valve
ORFA Industrial Products Industry and Trade Inc. sells Wafer Type Electric Actuated Butterfly Valves. These valves offer ideal solutions for fluid control in industrial and commercial applications. Butterfly valves use a disc rotating around a shaft positioned vertically as the closing element. By rotating around its axis, the disc completely opens or closes the pipe section. Sealing is achieved between the metal flap and the elastic or plastic sealing elements lining the body. These elements also act as a gasket on the flange between the valve and the pipe.
The Wafer Type Electric Actuated Butterfly Valve stands out for its easy installation, high performance, and reliability. The disc, the closing element, allows fluid to flow freely or blocks it. Before installation, the disc should be checked for free movement. The valve stem can be positioned horizontally or vertically, but horizontal installation is preferred for valves larger than DN300.
The advantages of this type of butterfly valve include low pressure loss, easy opening and closing, high sealing, light weight, and a small footprint. Single-acting pneumatic actuators automatically close when the valve is opened, saving energy and minimizing operator intervention.

Wafer Type Electric Actuated Butterfly Valve Working Principle
1. Disc and Shaft Mechanism: The basic component of the Wafer Type Electric Actuated Butterfly Valve is a disc-shaped closing element that rotates around a vertically positioned shaft. This disc controls fluid flow by opening and closing a full section of pipeline.
2. Electric Actuator: An electric actuator is a device that provides the power needed to rotate the valve shaft. When it receives an electrical signal, a motor within the actuator activates, rotating the valve disc to a specific angle. This angle determines whether the valve is open or closed.
3. Sealing: A butterfly valve provides a seal between the metal surface of the disc and the elastic or plastic sealing elements within the valve body. These elements prevent fluid leakage when the valve is closed. They also act as a gasket on the flange between the valve and the pipe, enhancing sealing.
4. Opening and Closing Movement:
Opening: When the electric actuator commands the valve to open, the disc rotates around the shaft and releases fluid from the pipeline. The disc moves to the fully open position, allowing flow to pass through.
Closing: When the closing command is given, the disc rotates in the reverse direction, closing the pipeline and preventing the passage of fluid.
5. Position Control: Electric actuated butterfly valves can precisely control the disc position. This allows for partial opening or closing of the valve. The actuator can regulate fluid flow by maintaining a specific position.
6. Mounting and Position: The valve stem can be mounted horizontally or vertically. However, for large-diameter valves (DN300 and above), horizontal mounting is preferred. This ensures more efficient and reliable disc movement.
Butterfly Valve Advantages
Remote Control: Thanks to the electric actuator, the valve can be controlled remotely and automatically.
Fast Response: Electric actuator valves provide effective solutions in emergency situations with their fast opening and closing times.
Precise Control: The position of the disc can be adjusted precisely, thus maintaining the fluid flow rate at the desired level.
Durability: Manufactured using stainless steel and high-quality materials, these valves are long-lasting and reliable.
