摘要：
An actuator for a fluid regulator includes two or more control springs operatively connected to a diaphragm such that at least two of the control springs bias the diaphragm independently in parallel and have different natural frequencies. A method for retrofitting a prior art actuator to include a second control spring is also disclosed.
