Prevent pulsating pressure of your pressure gauge!

Example of use



  • Abrupt surge pressure on the pressure gauge is absorbed by the ASK proprietary damper mechanism. So the possibility of pressure gauge breakdown is completely eliminated.
  • Pulsation at the normal pressure is also removed; therefore, durability of the pressure gauge is greatly improved.
  • SAH-100 is a needle valve to allow pulsation to be adjusted. Furthermore, the product can also be used as a stop valve.
