Brief Introduction

ZYA9000 piston airbag type water hammer arrestor has a air chamber inside body, and a piston at the bottom. When the water hammer shock wave goes into the water hammer arrestor, the water shock wave works on the piston, the piston will move to the direction of the air chamber, the piston moves up and down under the pressure of chamber and water hammer to form a dynamic balance, so that the irregular water shock wave will be  eliminated.
