Lug butterfly valve
The Lug Butterfly Valve is a high-quality valve solution designed to cater to a wide variety of industrial applications. It combines the efficiency and compactness of a butterfly valve with the robustness and stability of a lug style design, offering superior control over fluid flow in various systems.
Constructed from top-tier materials, the Lug Butterfly Valves is built to withstand extreme temperature and pressure conditions. Its key feature is the lug style design, which involves threaded inserts at both sides of the valve body. This allows it to be installed into a system using two sets of bolts without nuts, enabling it to be sandwiched between two flanges. This design makes the lug butterfly valve an ideal choice for end-of-line service where downstream removal of piping components is necessary without taking the entire system out of service.
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, thus controlling the fluid flow. This simple operation makes the valve user-friendly and easy to maintain.
The Lug style Butterfly Valve can come equipped with a manual, pneumonic, 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 Lug 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 Lug Butterfly Valve is an efficient, durable, and versatile valve solution suitable for a diverse range of industrial applications. Its lug design, simple operation, and robust construction make it a reliable choice for controlling the flow of fluids in your system.
