0927 Series Solenoid Valve 0927200 1/2'' Brass Normally Closed Valve
0927 Series Solenoid Valve 0927200 1/2'' Brass Normally Closed Valve
0927200 is a 2/2-way normally closed (N.C.) diaphragm pilot-operated solenoid valve. It belongs to the 0927 series and is designed for general-purpose control of air, water, oil, and other compatible fluids.
Working Principle
The 0927200 uses a pilot-operated diaphragm structure. When the coil is de-energized, the valve remains closed. When the coil is energized, the pilot circuit changes the pressure balance across the diaphragm, allowing the main valve to open.
Because it is pilot-operated, the valve requires a minimum pressure differential for normal operation. An older Norgren/Buschjost technical document for the 09270 series specifies a minimum differential of 0.7 bar, so the exact minimum should be confirmed against the particular manufacturer's version before replacement.
Typical Applications
The 0927200 can be used for fluid control in:
Pneumatic systems
Water supply systems
Air compressors
Industrial pipelines
Automatic production equipment
Light oil systems
General process-control equipment
For contaminated media, an upstream filter is recommended to reduce the risk of particles affecting the pilot or diaphragm mechanism.
