Rolling Diaphragm is a device that uses a flexible, usually cylindrical diaphragm as the active component to move a plunger or gate in a linear motion. In this design, the diaphragm is moved by a motor and rollers, which create a rolling wave motion that drives the diaphragm and plunger in a linear path. This type of device is typically used in hydraulic or pneumatic applications for controlling pressure regulation and flow control.
