METHOD AND APPARATUS FOR DAMPING AN ACTUATOR ON A FLUID REGULATOR

摘要

A damped actuator for a fluid regulator (10) includes a diaphragm (28) disposed in a housing and a damper (100) arranged to stabilize movement of the diaphragm (28) in response to changes in pressure inside the housing. The damper (100) includes a ball check valve (104) arranged to allow air to exhaust out of the housing when above a preselected pressure. The damper (100) may include interchangeable components so as to be modifiable to have different set point pressures to achieve different backpressures inside the housing.
