product use
Q41F type PN16~PN64 valve for each kind of pipeline Class150~Class1500, PN16~PN64, JIS10K~JIS20K, used to cut off or connect the line of medium, use different materials, can be separately applied to water, steam, oil, liquefied petroleum gas, natural gas, coal gas, nitric acid, acetic acid, oxidizing medium, urea and other media.
product characteristics
1. In all kinds of valves, the flow resistance of the ball valve is the smallest. When the full diameter ball valve is opened, the sphere passage, the valve body passageway and the connecting pipe diameter are equal and become a diameter, and the medium can flow almost without loss.
2. The ball valve is rotated 90 degrees can be closed to open, open and close rapidly. Compared with the same gate valve, cut-off valve, small ball valve, light weight, easy to install the pipe
