Zoloto butterfly valve is a type of valve used for regulating or isolating the flow of fluids in a piping system. It consists of a circular disc or "butterfly" that is mounted on a shaft in the center of the valve body. When the valve is open, the disc is rotated so that it is parallel to the flow of fluid, allowing it to pass through the valve unimpeded. When the valve is closed, the disc is rotated so that it is perpendicular to the flow of fluid, blocking it completely.Zoloto butterfly valves are commonly used in industrial applications, particularly in the chemical and pharmaceutical industries, where they can handle corrosive and abrasive fluids with ease. They are also commonly used in water and wastewater treatment facilities, as well as in HVAC systems, due to their ability to provide precise control over the flow of fluids.
