0927400 1'' Diaphragm Solenoid Valve BEST-NR.0200 AC220V DC24V

0927400 is a 2/2-way normally closed (N.C.) pilot-operated diaphragm solenoid valve in the 0927 series. It is the 1-inch port / 25 mm orifice size of the series and is commonly used for controlling air, water, light oil, and other compatible fluids.

Working Principle

The 0927400 uses a pilot-operated diaphragm structure.

When the coil is de-energized, the valve remains closed. When the coil is energized, the pilot mechanism changes the pressure balance above the diaphragm, allowing the main valve orifice to open.

Because it is a pilot-operated design, the valve requires a suitable pressure differential for reliable switching. This is an important consideration when using it in low-pressure or zero-pressure applications.

Typical Applications

The 1-inch 0927400 is suitable for fluid-control systems such as:

Air compressors
Pneumatic equipment
Water supply systems
Industrial pipelines
Automatic production equipment
Light-oil control
Process-control systems

The brass body and selectable NBR/EPDM/FKM sealing configurations allow the valve to be matched to different media and temperature conditions.
