Pump Control Valve

الوصف

Basically, centrifugal pumps should be started in front of the closed outlet valve, and after the pump pressure reaches zero discharge pressure (Shut off Head), the outlet valve should be opened slowly, so that firstly, it is easier to start the pump, and secondly, to prevent ram blow.

To be implemented Also, when turning off the pump, the outlet valve of the pump should be closed slowly and then the pump should be turned off to reduce the impact of the ram to the minimum possible. For this purpose, it is necessary to spend a huge amount of money to use ordinary shut-off valves such as butterfly valves or sliding valves equipped with electric drives with a suitable command circuit system to open and close the valve in time, or easily use the valves He used the pump control valve with high reliability, long life, more safety and lower cost. Since the body of these valves is globe type, as a result, they have a longer life than other valves, also instead of the 380 volt three-phase electrical system, you can use D.C. electricity in different voltage types, which brings more safety.
