How A 2-Way Normally Closed Solenoid Valve Works

How does a 2-way Normally Closed Solenoid Valve work? What is a Solenoid Valve? A solenoid valve is an electromechanical device used for controlling liquid or gas flow. Solenoid valves make automation of fluid and gas control possible. Modern solenoid valves offer fast operation, high reliability, long service life, and compact design. What are the different parts of a 2-way Normally Closed Solenoid Valve? Stop Magnetic stainless steel Lead Wires Electrical Connection Coil When energized produces a magnetic field. Coil Housing Plunger Guide Tube Compensating Seal Used in 3- and Normally Open vales Plunger Magnetic stainless steel Compensating Spring Valve Body Body Orifice Seal Plunger Return Spring Stainless steel, provides positive plunger return regarless of mounting position. O-Ring Body Seal Inlet Port Outlet Port How does a 2-way Normally Closed Solenoid Valve work? 1 The valve is controlled by electrical current that passes through the solenoid. When power is off plunger is down seals against orifice and closes the valve. Pressurized liquid or gas goes through the Inlet Port into valve cavity. Pressurized liquid or gas When the coil is energized, a magnetic field is created, causing plunger to rise up inside valve unsealing orifice and opening valve. The plunger directly opens an orifice inside the valve. This allows the pressurized liquid or gas to pass the valve.
