    Product overview

    700X pump control valve is a kind of reverse valve installed at the pump outlet of high-rise buildings and other water supply systems to prevent medium backflow. When the water pump is about to stop supplying water, the valve closes slowly about 90% to prevent water hammer and water hammer caused by sudden shutdown; when the pump stops completely, the valve closes completely again to prevent the return flow of water from the pump, effectively protecting the pump from the impact of the return flow and causing reversal. This product is an indispensable protective device for pump outlet. The valve is streamlined. It can be opened and closed accurately through the guidance of the solenoid valve. It is safe and reliable to use. It can effectively prevent the sound of water hammer and water hammer. It has a long service life and is easy to install and maintain.
