Pulsation dampener


The pulsation dampener is used in cases of unstable pneumatic signal in the sensing line. This accessory helps smooth out abnormal pulsations or spikes and improve regulator performance.

It is often installed when it is not possible to comply with the distance between the regulator and the sensing line connection recommended by the manufacturer or when the downstream line size (diameter) is too small, generating excessive turbulence due to high velocity.

This accessory helps to minimize pilot’s contamination from gas dirt and is suitable for natural gas and all non-aggressive gases applications.
