700X Pump Control Valve Descriptions
700X pump control valve is one type of non-return valve which is applicable to be mounted on the pump outlet of high building and other water supply systems to prevent of medium backflow. When the water pump is about to stop water supply, the valve will close about 90% in advance to prevent of water hammer and water attack caused by pump sudden stop. When the pump stops fully, the valve will close fully then to prevent of water backflow, so that it protect the pump effectively to be safe from reversal caused by water backflow attack.
700X pump control valve is must protector mounted on the pump outlet. It is streamline design, achieving its open and close through solenoid valve pilot control. It has safe and reliable performance to prevent of water hammer and attack. It has long service life and convenient installation and repair. Flowspec Luokai can manufacture the 700X pump control valve mounted on the pipeline sizes≤DN600mm.
