EN331 ball valve is available in ¼ inches to 4 inches sizes. The valve can have different finishes according to the en331 standard. The finishes can be brass nickel plated body and PTFE seats. The different sizes are used in different applications. The en331 pn 25 has ISO228 thread type. The NBR o-ring is a standard feature of the en331 mop5 can operate up from cryogenic temperatures to 80 degrees Celsius temperatures. The en331 valve can be used in different applications with different dimensions. The working pressure of the en331 approved ball valves can range differently. The most common working pressure for these valves is 5 bar. There are different references inside the en331 standard such as AL331115, Al331122 and Al331128. Each of them have different properties that specify them for different applications. The EN331 Gas Approved Brass Ball Valves are used in gas pipe lines for leak proof connections. The size differences of each reference type of the valves ranges from 15mm, 22mm to 28mm. The connection of the Gas Ball Valves EN 331 is compression type. The body is brass and the plating is nickel. The BSPT taper male thread is needed for the installation of the En 331 Approved Lever Operated Ball Valve.
