Operation

The Upstream Pressure applies balanced opening and closing hydraulic forces under the Diaphragm and above the Plug . The Downstream Pressure applies hydraulic closing force under the plug, which seeks to reach equilibrium with the Set Spring force.

Should rise above setting, the hydraulic closing forces rise above the mechanical force of the spring, pushing the plug to modulate closed, and reducing P2 back to setting
