Principle

PRECISE® B11 series submerged multi-jet sleeve valve's flow control and energy consumption are achieved by switching the amount of jet of the sleeve. The sleeve jets are specially designed for each specific engineering. The sleeve valve has excellent anti-cavitation performance, through the unique anti-cavitation structure, so that the occurrence of cavitation valve could be away from the wall metal surface area, avoiding cavitation damage to the valve and reducing valve vibration and noise during run-time.

In practical operation of each project, the PRECISE ® B11 series of submerged multijet valve sleeve can provide optimal flow control or pressure control.
