PRODUCT INTRODUCTION
1. Description
The 700X pump control valves is a kind of check valves intended for installation at outlets of pumps in high-rise buildings and other water supply systems to prevent reverse flow of the medium. When the pump is about to stop water supply, the valves first shuts off slowly by about 90% so as to avoid water hammer caused by the sudden shutdown of the pump. When the pump comes to a complete stop, the valves then shuts off completely so as to prevent the reverse flow of water pumped out. This can effectively protect the pump and avoid the reverse rotation caused by the impact of reverse flow. This product is an indispensable protective device at outlets of pumps.It has a streamlined design, can realize precise turning on/off through guidance and is controlled by the solenoid valves. Furthermore, our pump control valves is safe, reliable, effectively avoids water hammer, boasts a long service life and is easy to install and maintain.
Pressure Rating: PN10. PN16. PN25/Class150
Size Range: DN20mm-DN800mm (3/4" - 32")
Test and inspection: GB/T 13927 API598
2. Application
The valves eliminates damaging water surges (hammer) caused when pump starts up and shuts off. The electrically activated valves gradually opens when pump starts up, and slowly closes before the pump is switched off. The valves also operates as a slow control check valves, preventing reverse flow and water hammer when power failure.
