Switch Options
An improved, more rugged method of damping turbulence, pulsations, and surges — preventing false actuation signals.

Identical in function to the Dash Pot (-DP) model but utilizing damping action on the stem itself with a special built-in, fully adjustable dampener. This model is particularly suited to the pulsating action of positive-displacement pumps.
Damping action applied directly to the stem — more rugged than external dash pot designs.
Special built-in dampener is fully adjustable to match your specific flow conditions.
Eliminates false signals caused by turbulence, pulsations, and surges in the flow.
Particularly suited to the pulsating action of positive-displacement pumps.
Both options prevent false actuation from turbulent flow. The stem dampener applies damping directly to the stem mechanism, while the dash pot uses a separate pneumatic damping assembly. The stem dampener is generally more compact and better suited for pulsating pump applications.
