NOR'EAST CONTROLS 30685491-004 Reverse Diaphragm 01-11

The NOR'EAST CONTROLS 30685491-004 functions as a Reverse diaphragm that serves pneumatic HVAC control systems. The flexible material diaphragm functions together with pressure differentials to operate valves or dampers inside the system. The connected component responds to diaphragm movement that occurs when pressure levels change. Reverse diaphragms exist in air handlers and valve actuators and dampers. The application of diaphragms in HVAC systems provides dependable and accurate flow control which results in improved HVAC performance alongside temperature management capabilities. These devices maintain themselves easily because of their basic design.
