Product pressure grade: SDR11, SDR13.6, SDR17, SDR21.
Application areas:
Polyethylene pipe industry globe valves used in urban water supply projects in rural areas, industrial and mining water projects, irrigation and livestock drinking water, garden irrigation projects.
***Workflow of HDPE Stop Valve
HDPE Stop Valve is closed parts (valve) moves along the centerline of the valve seat. According to this form of valve moves, changes in port of the valve seat and the valve stroke is directly proportional relationship. As such the valve stem to open or close the relatively short trip, but also very reliable cut-off function, and because the trip is proportional valve port and valve changes, very suitable for flow regulation. Therefore, this type of valve is suitable for cutting or regulation and throttling.
