The Diaphragm Solenoid Valve (Solenoid Valve Diaphragm Type) is a valve that controls the flow of liquids or gases using a diaphragm and solenoid to open and close the valve. It is commonly used in automatic systems such as water supply systems, irrigation systems, compressed air systems, and various industries.
How Solenoid Valve Diaphragm Type Works
Main Components
Solenoid Coil (Electromagnetic Wire Winding): Creates a magnetic field when electric current flows through it.
Plunger (Movable Iron Rod): Moves up and down with the magnetic field.
Diaphragm (Flexible Rubber/Silicone Sheet): Opens and closes the liquid flow path.
Pilot Port (Pressure Control Port): A small port that helps control pressure on both sides of the diaphragm.
Operating Mode
Normal Closed (NC) – Normally Closed
No power → Plunger closes pilot port → Pressure on both sides of diaphragm is equal → Diaphragm closes valve
Power applied → Plunger is drawn up → Pilot port opens → Pressure above diaphragm decreases → Fluid from below pushes diaphragm up → Valve opens
Normal Open (NO) – Normally Open
Similar principle but reversed pressure side → No power valve is open, with power valve closes
Advantages of Diaphragm Valve
Quick opening and closing
No leakage (because diaphragm does not wear like other valves)
Easy maintenance
Suitable for clean liquids such as water, air
Usage Details
Drinking water system used to control water in filters and cold water machines
Automatic watering system opens and closes water according to schedule
Food/Pharmaceutical industry used with clean liquids that need precise control
Pneumatic system controls air supply in machinery
Home appliances such as washing machines, coffee makers
