Normally Closed (Air to Open)
Valve opens when air pressure is applied and closes when air is released.
Normally Open (Air to Close)
Valve closes with air pressure and opens when air supply is removed.
Working Principle of Pneumatic Diaphragm Valves
A pneumatic diaphragm valve operates through compressed air supplied to an actuator assembly. When air pressure is applied, the actuator moves a flexible diaphragm connected to the valve stem. This movement adjusts the valve position to regulate the flow of process media.
Depending on system requirements, the valve can fully open, fully close, or continuously modulate flow rates to maintain desired operating conditions. The responsive nature of pneumatic actuation allows accurate control of pressure, temperature, and fluid movement within industrial systems.
The diaphragm acts as a sealing barrier between the process fluid and operating components, helping reduce leakage risks while enhancing reliability and operational safety.
