Product Details of Solenoid Valve Model : WD25L(1")-N-4-AC110V / Diaphragm Type 2/2 way NC, NBR Seal, For Water, Air, Gas L

The Diaphragm type 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 a Diaphragm Solenoid Valve Works

Main Components

• Solenoid Coil (Electromagnetic Wire Winding): Creates a magnetic field when electrical current flows through it.
• Plunger (Moveable Iron Rod): Lifted up/down by the magnetic field.
• Diaphragm (Flexible Rubber/Silicone Sheet): Opens and closes fluid pathways.
• 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 electricity → Plunger closes pilot port → Pressure on both sides of the diaphragm is equal → Diaphragm closes valve.
• When powered → Plunger is pulled up → Opens pilot port → Pressure above the diaphragm decreases → Fluid from below pushes the diaphragm up → Valve opens.

Normal Open (NO) – Normally Open 

• Similar principle but pressure sides are reversed → When no power valve is open, when powered valve closes.

Advantages of Diaphragm Valves

• Rapid opening and closing.
• No leakage (because the diaphragm does not wear like other valves).
• Easy to maintain.
• Suitable for clean fluids such as water, air.

Usage Details

• Potable water system – Controls water in filters and cold water machines.
• Irrigation systems – Opens/closes water according to schedule.
• Food/Pharmaceutical industry – Used with clean fluids that need precise control.
• Pneumatic systems – Controls air supply in machinery.
• Home appliances – Such as washing machines, coffee makers.
