Q41FA Flange ball valve

Product Overview

The flange ball valve operates by rotating the valve stem to open or close the passage. It features easy operation, compact size, reliable sealing performance, simple structure, and convenient maintenance. The sealing surface and spherical surface remain in a closed state, making them resistant to erosion by the medium. This valve is widely used in various industries such as petroleum, chemical engineering, power generation, papermaking, nuclear energy, aviation, and rocket propulsion, as well as in daily applications.

Product Features

Simple structure, compact size, and lightweight

The fluid resistance is low, with its resistance coefficient equal to that of a pipe segment of the same length.

The ball valve is highly reliable and compact. Its sealing surface is widely made of plastic, offering excellent sealing performance and broad applicability. It features convenient operation with rapid opening and closing—only a 90° rotation is required to achieve full opening or closing—facilitating remote control. The valve is easy to maintain due to its simple structure and movable sealing ring, enabling quick disassembly and replacement.
