Wafer butterfly valve
The Wafer Butterfly Valve is a versatile valve solution designed to cater to a wide variety of industrial applications. It seamlessly combines the compactness and efficiency of a butterfly valve with the convenience and cost-effectiveness of a wafer-style design, offering superior control over fluid flow in various systems.
Constructed from high-quality materials, the Wafer style Butterfly Valve is engineered to withstand varying temperature and pressure conditions. Its key distinguishing feature is the wafer-style design. This design allows the valve to be sandwiched between two flanges using bolts or studs and nuts, making it an ideal choice for large valve installations due to its lightweight and cost-effective nature.
One of the key advantages of this valve is its straightforward operation. The valve features a disc that pivots on a rod. When the rod is rotated by a handle or actuator, it opens or closes the valve, controlling the fluid flow. This simple operation makes the valve user-friendly and easy to maintain.
The Wafer type Butterfly Valve can come equipped with a manual, pneumatic, hydraulic, or electric actuator, depending on your specific needs. Manual actuators are operated using a handwheel or lever, while automated actuators provide remote operation and increased safety.
The valve features a full or reduced bore design, providing minimal resistance to fluid flow when fully open, maximizing flow rates, and reducing pressure drop across the valve. This makes it an ideal choice for systems requiring high flow rates.
The body of the Wafer Butterfly Valve is typically made from metals like stainless steel, cast iron, or bronze, providing excellent resistance to corrosion and ensuring a long service life. The internal components of the valve are precision-engineered to provide a tight seal when closed, preventing any leakage and maintaining the integrity of the system.
In conclusion, the Wafer Butterfly Valve is an efficient, durable, and versatile valve solution suitable for a diverse range of industrial applications. Its wafer-style design, simple operation, and robust construction make it a reliable choice for controlling the flow of fluids in your system.
