700X pump control valve is a kind of check valve which is 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 water supply, the valve shall be slowly closed for about 90% to prevent water hammer and water hammer caused by sudden stop of the pump; when the water pump is completely stopped, the valve shall be fully closed to prevent the backflow of water from being pumped out and effectively protect the pump from reverse rotation caused by the impact of backflow. The product is an essential protection device for pump outlet. The valve is of streamline design and can be opened and closed accurately through the guidance and control of the solenoid valve. It is safe and reliable to use and effectively prevent water hammer and water hammer sound. It has a long service life and is convenient for installation and maintenance.
1. The valve body adopts full channel and streamline design, with small fluid resistance and large flow rate.
2. The joint of body, cover and piston rod is double sealed by sealing gasket and sealing ring without leakage.
3. Double guide of valve body, piston cylinder and piston ensures stable and reliable movement.
4. All stainless steel piston cylinder, integral casting piston and NBR sealing ring. Perfect combination greatly prolongs service life.
5. The detachable valve seat with advanced technology has ingenious structure, novel conception and convenient maintenance and replacement.
6. For the piston cylinder with guide hole, properly increase the resistance to make the piston movement more stable.
