Wafer Type Butterfly Valve Single Acting Pneumatic Actuator
At ORFA Industrial Products Industry and Trade Inc. , we are proud to offer the highest quality valves in the industry. Our single-acting pneumatic actuated Wafer-Type Butterfly Valves are an excellent choice for your industrial applications. Our products' superior performance, durability, and sealing properties make your operations more efficient and safer.
Wafer-type butterfly valves offer a simple and effective closing mechanism. These valves rotate around their axis when installed, using a disc as the closing element to open or close the pipe section. Sealing is achieved between the disc and the elastic or plastic sealing elements lining the body, which also act as a gasket on the flange between the valve and the pipe.
During installation, the disc should be checked for free movement. The valve stem can be horizontal or vertical, but horizontal installation is preferred for valves larger than DN300. These valves offer advantages such as low pressure losses, easy opening and closing, good sealing, light weight, and a small footprint. The use of a reducer type is recommended for all diameters, and only the reducer type is available for butterfly valves DN350 and larger.

Wafer Type Butterfly Valve with Single Acting Pneumatic Actuator - Working Principle
Wafer-Type Butterfly Valves with Single-Acting Pneumatic Actuators are frequently preferred in modern industrial systems, providing effective and reliable flow control solutions. These valves are used to control a variety of fluids (water, seawater, dust, gas, wastewater, and air). Here's a detailed overview of their operating principles.
Working Mechanism
The operating principle of wafer-type butterfly valves is based on the rotation of a disc, used as a closing element, around a shaft positioned vertically. When the valve is open, the disc aligns with the pipeline, allowing flow to pass freely. When the valve is closed, the disc completely closes the pipeline, stopping flow.
Disc and Shaft Movement: The butterfly valve disc rotates around a shaft located in the center of the valve. The shaft is usually located at the top and bottom of the valve body. Rotation of this shaft causes the disc to open or close. The disc can rotate between 0° (fully closed) and 90° (fully open).
Pneumatic Actuator: A single-acting pneumatic actuator uses compressed air to open or close a valve. Single-acting actuators use air pressure to provide movement in one direction only, while a spring provides movement in the opposite direction. This allows the valve to automatically return to the closed or open position in the event of a power outage.
Sealing Elements: In butterfly valves, sealing is achieved between the metal disc and the elastic or plastic sealing elements lining the inside of the body. These elements prevent the disc from completely sealing the pipeline when closed, preventing flow leakage. These sealing elements also act as a gasket on the flange between the valve and the pipe.
Actuator Control: Pneumatic actuators are controlled by control signals. The air pressure supplied to the actuator is adjusted through control systems. These systems determine whether the valve is open or closed and make the necessary pressure changes.
Advantages and Features
Low Pressure Loss: Butterfly valves offer minimal resistance to flow, which minimizes pressure losses.
Quick and Easy Opening/Closing: It can be opened and closed quickly and easily with a 90° rotation of the disc.
Good Sealing: Metal disc and elastic/plastic sealing elements provide high sealing.
Lightweight and Compact Design: Butterfly valves can be easily installed even in narrow spaces thanks to their lightweight and compact structure.
Versatile Use: Can be used with various fluids and application areas.
Application Areas
Wafer Type Butterfly Valve Single Acting Pneumatic Actuated valves are effectively used in various industrial areas such as heating, ventilation and air conditioning systems, water treatment and distribution systems, mining industry, shipbuilding and drilling facilities, sugar industry, food and chemical enterprises, fire extinguishing systems.
The operating principle of Wafer Type Butterfly Valves with Single-Acting Pneumatic Actuators is based on a simple and effective closing mechanism. The fast and reliable control provided by pneumatic actuators makes these valves preferred in industrial applications. These valves offer a wide range of applications, with advantages such as low pressure loss, easy opening/closing, good sealing, and light weight. These products, offered by ORFA Industrial Products Industry and Trade Inc. , are designed to meet high quality and performance standards.
