Ball valve with flange connection, 304 stainless steel material
The Q41F ball valve has two structural forms: full-bore and reduced-bore. Reduced-bore ball valves are suitable for pipelines transporting gases or media with physical properties similar to water, as they are approximately 30% lighter than full-bore ball valves, which helps reduce pipeline load and lower costs.
The Q41F ball valve can be applied to various media such as water, steam, oil products, liquefied petroleum gas (LPG), natural gas, coal gas, nitric acid, acetic acid, oxidizing media, and urea.
Its advantages lie in the stability of quality and high performance, making it widely used in various pipeline equipment such as urban gas, urban heating, petrochemical, shipbuilding, steel, pressure regulating stations, and power plants.
Product Features:
- Small fluid resistance, with a resistance coefficient equivalent to that of a pipe section of the same length; simple structure, small size, and light weight.
- Tight and reliable sealing, with valve sealing surfaces widely using plastics for good sealing performance, and it is also widely used in vacuum systems.
- Easy to operate and quick to open/close, requiring only a 90° rotation from fully open to fully closed, facilitating remote control.
- Convenient maintenance, as the pneumatic ball valve has a simple structure, and the sealing ring is generally movable, making disassembly and replacement easy.
- When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, preventing erosion of the valve sealing surfaces when the medium passes through.
