1 more element
A control regulator comprising:
- a valve body forming a fluid inlet and a fluid outlet connected by a fluid passageway;
- a valve plug disposed within the valve body, the valve plug cooperating with a valve seat to control a flow of fluid through the valve body;
- an actuator coupled to the valve body, the actuator including a diaphragm assembly that is operatively connected to the valve plug by a valve stem, the diaphragm assembly including a diaphragm having an upper layer, a middle layer, a lower layer, and a locally weakened area that forms a pressure relief mechanism;
- and a diaphragm plate that supports the diaphragm,
- wherein the locally weakened area is formed by an opening in the middle layer.
