Gauge Snubbers | Features and Benefits

AS-Schneider Gauge Snubbers are used to improve the output or readability of the instrument, and to reduce the effect of pressure surges on the instrument.

They also limit the external discharge of the pressure medium, in the event a discontinuity should occur on the instrument side of the snubber. Closing the valve increases the dampening action.
