700X Features
700X pump control valve is installed at the pump's outlet in high building and other feeding system to prevent fluid flowing backwards. Before the pump stops, the valve closes 90% or so ahead to prevent water hammering and water hitting at the pump's instant stop; after the pump completely stops, the valve closes fully to prevent fluid flowing backwards at the outlet of the pump to protect the pump and prevent it from turning backwards due to backward flow of the fluid. This is necessary protection equipment for the pump. It is flow-line designed and it can open or close to electric-magnetic valve's pilot. It is safe to use and it is easy to install and to maintain this kind of valve.

JD745X Features
JD745X pump control valve is mounted on the water pumps outlet pipeline of the high buildings and other water
supply systems to prevent of the mediums back-flow and the water hammer and water shock.
JD745X pump control valve has good effect of water hammer removal. Integrating the technical principles of water
hammer removal by means of slow open, quick close and slow close, so as to prevent of the water hammers at both
pump start and stop.
Easy operation. The valve will open or close automatically as per the operation procedures of the pump, once
operates the On-Off button of the pumps motor.
Good effect of energy saving. The valve body is designed as full-path straight-flow type, resulting in small
pressure loss, big flow, small volume and light weight.
