The statement of oxygen pipeline valve

1、This valve consists of valve body, bonnet, valve disc etc.

2、Ball type valve body can balance the pressure.

3、This valve is manual to operate, clockwise turn the handwheel to shut the valve, and anticlockwise turn the handwheel to start the valve.

4、No ball bearing for those less than DN50, but DN150, DN150,DN200,DN250,DN300etc. these big diameter valves are extra equipped with auxiliary valve disc, and the medium flows from the upper part of valve disc to its down part.

Main characteristics

1、This product is a specially-designed silicon brass stop valve, mainly used on the pipeline paid with the pressure by oxygen pressure machine.

2、This valve is agile to start and shut, according to different diameters,it adopts two structures, small diameteris the general structure, big one is equipped with auxiliary valve disc, and reduce the startup&shutting moment by balancing the pressure differences between valve frontal and valve back.

4、The outside part of valve rod can prevent the dust and smear, and the bracket bearing adopts the alicyclic fluoride as lubrication.
