Middleeast valve is a top Wafer butterfly valve suppliers in Saudi Arabia. We supply to cities like Ajman, Hatta, and Kho Fakkan.
A wafer butterfly valve is a type of industrial valve used to control the flow of various fluids, such as gases, liquids, and slurries, within a pipeline. It is named after its disc or “butterfly” shaped closing mechanism.
The term “wafer” in “wafer butterfly valve” refers to the valve’s design, which allows it to be sandwiched between two pipe flanges without the need for additional nuts and bolts. This design makes installation and maintenance easier compared to other types of valves.
The main components of a wafer butterfly valve include:
- Body: The main housing of the valve that contains the flow path.
- Disc or Butterfly: The disc is a flat, round or oval-shaped component that pivots within the valve to regulate the flow. It can be rotated 90 degrees from fully open to fully closed.
- Stem: The stem connects to the disc and is operated by the valve actuator. It controls the movement of the disc.
- Seat: The seat is a sealing element that comes into contact with the disc when the valve is closed, ensuring a tight shut-off.
- Actuator: The actuator is a mechanism responsible for opening and closing the valve. It can be manual (hand-operated), electric, pneumatic (air-operated), or hydraulic, depending on the application.
The primary function of a wafer butterfly valve is to regulate the flow of fluid within a pipeline. By adjusting the position of the disc, the valve can control the flow rate or completely shut off the flow. When the disc is rotated perpendicular to the flow direction, it blocks the passage of fluid, providing a tight seal. When the disc is rotated parallel to the flow direction, it allows fluid to pass through the valve.
When the valve is in the open position, the disc is turned parallel to the flow direction, allowing fluid to pass through the valve with minimal resistance. The disc is rotated 90 degrees to close the valve, effectively blocking the flow. The actuator is used to control the position of the disc. The seat ensures a tight seal when the valve is closed, preventing leakage.
Middleeast valve is a topmost Wafer butterfly valve suppliers in Saudi Arabia and are popular due to their compact design, ease of installation, and cost-effectiveness. However, their suitability for certain applications depends on factors such as pressure, temperature, flow rate, and the type of fluid being controlled.
