Name of Commodity: JIS F7474 Cast Steel 20k screw-down Check Angle Valves
 
Product Description
1. The flow path is simple, small dead zone and vortex area, scouring action by means of the media itself, which can effectively prevent the media from clogging. And has good self-cleaning properties.
 
2.Small flow resistance, flow coefficient smaller than the single seat valve, equivalent with the flow coefficient of double-seat valve.
 
It's suitable for the case of high viscosity fluid containing suspended particulate matter,or to request a place at right angles to the pipe. Its flow is generally bottom into the side.
