YNTO Stainless Steel Pneumatic Flanged 90° Quarter-Turn Ball Valve
The Pneumatic Flanged Ball Valve (Q641F) is a quarter-turn ball valve that features excellent sealing performance, high flow capacity, low flow resistance coefficient, simple structure, easy maintenance, and long service life.
Product Overview
The Pneumatic Flanged Ball Valve (Q641F) is a quarter-turn ball valve that features excellent sealing performance, high flow capacity, low flow resistance coefficient, simple structure, easy maintenance, and long service life. The valve body channel and connecting pipe diameter are equal and consistent, allowing the medium to flow through with minimal loss. It is typically paired with a KES actuator and is commonly used in applications with strict sealing requirements. In addition to controlling gases, liquids, and steam, it is also suitable for controlling mediums containing fibrous impurities in water. This valve is widely used in various industries, including petroleum, chemical, metallurgy, light industry, papermaking, power generation, and refrigeration.
