Sensus QR-S Damping Device 319848-301 or if there is visibleThe Sensus QR S Damping Device is a purpose built mechanical component designed to optimize gas pressure regulator performance in high demand environments. Engineering teams developed this device to address the rapid ignition cycle requirements of modern high efficiency boilers, burners, and generators. When high efficiency equipment triggers an electronic ignition, the sudden draw can create significant negative pressure, often leading to excessive
