Automatic Water Control Valve
Description:
Hydraulic automatic flow water 400X-16 control valve automatically reduce a higher inlet pressure to a steady lower downstream pressure, regardless of chaning flow rate and varying inlet pressure.
This control valve is an accurate, pilot-operated regulator capable of holding down steam pressure to a re-determined limit. When downstream pressure exceeds the pressure setting of the control pilot, the main valve and pilot valve close drip-tight.
Size: DN 50 – DN 600
Flange drilling is suitable for BS EN1092-2 PN10/16.
Epoxy fusion coating for control valve body.
Principle of work
By the pressure transmission of the main valve with a small change in the pilot valve size and adjustment.
Installation:horizontal,vertical installation for more information please contact us.
Features
1.This control valve adjust and maintain a preset maximum flow rate regardless of the outlet how the upstream and downstream of changes in pressure.
2.This control valve is used to adjust the flow pipe from the pump or irrigation system flow,head road or from the flow of the secondary pipeline network traffic.
