Stainless steel flange ball valve Q41F-16P is an important type of valve mainly used for pipeline connection and control. Its basic structure includes valve body, sphere, valve seat, valve stem, and actuator. There is a circular channel in the middle of the sphere, and the valve can be opened and closed by rotating the sphere. Valve seats are usually made of elastic materials such as polytetrafluoroethylene to ensure good sealing performance of the valve in the closed state
Working principle
Stainless steel flange ball valves rely on rotating valve stems to keep the valve open or closed. When the valve stem rotates 90 degrees, the channels on the sphere align or offset with the channels on the valve body, thereby achieving the opening or closing of the fluid. This design enables the valve to open and close quickly, with simple and fast operation, and is easy to achieve automation and remote control
Applicable medium and temperature range
Stainless steel flange ball valves are suitable for various media, including water, steam, oil products, liquefied gas, natural gas, coal gas, nitric acid, acetic acid, oxidizing media, urea, etc. It has a wide temperature range, from -20 ° C to+180 ° C, and can even reach 550 ° C
Material and Manufacturing Standards
The valve body material of stainless steel flange ball valve is usually stainless steel 304, 316 or 316L. Manufacturing standards include national standards such as GB, German DIN, American API, and ANSI. These standards ensure the reliability and durability of valves under different operating conditions
Application areas and maintenance
Stainless steel flange ball valves are widely used in fields such as petroleum, chemical, power, environmental protection, water conservancy, heating, water supply and drainage, industry, and machinery.
