SG series water hammer absorberDetailed product description：

The SG9000-16/25P piston type water hammer absorber can effectively eliminate irregular water shock waves and oscillations that may occur due to water hammer and surge in the transmission system of various fluids without the need to prevent fluid flow, thereby achieving the purpose of eliminating destructive shock waves and providing protection.

Working Principle
The SG9000-16/25P piston type water hammer absorber has a sealed air chamber inside, with a piston at the lower end. When the shock wave enters the water hammer absorber, the water hammer wave acts on the piston, and the piston will move towards the air chamber. The stroke of piston movement is related to the gas pressure in the chamber and the size of the water shock wave. Under the dual action of gas at a certain pressure and irregular water shock, the piston moves up and down to form a dynamic balance, effectively eliminating irregular water shock wave oscillation.
