INTRODUCTION
The U.S. Solid 1/4 in normally open brass solenoid valve is designed for electrically controlled ON/OFF flow control in air, water, oil, pneumatic, and compatible fluid systems. The valve remains open when power is off and closes when the 12 V DC coil is energized, making it suitable for systems that require an open flow path by default. Its direct-acting design operates from 0 PSI without requiring a minimum pressure differential. The 2.5 mm orifice supports working pressures up to 319 PSI, while the VITON fluoroelastomer seal provides reliable sealing across a -30°C to 150°C temperature range. The compact brass body provides a sturdy construction for equipment and piping installations, and IP65-rated protection helps resist dust and water. With a Kv 0.18 m3/h flow coefficient and 16 W rated power, the valve is suitable for industrial automation, pneumatic equipment, air compressors, water systems, and other compatible fluid-control applications.

CE CERTIFICATION
VALVE ATTRIBUTES
Ingress Protection: The listed protection class is IP65. Keep the connector properly assembled and follow the product documentation for installation and maintenance.
Disconnect electrical power and depressurize the line before installation, inspection, or servicing. Confirm fluid compatibility, thread fit, and system pressure and temperature limits before operation. Do not exceed the ratings of the valve or connected components.
FAQ
1. What is the valve’s normal state?
It is normally open: the valve remains open when the coil is de-energized and closes when the rated voltage is applied.
2. Does this direct-acting valve require a minimum inlet pressure?
The product data specifies operation from 0 PSI without a minimum pressure differential.
3. What fluids can it control?
The listing specifies air, water, oil, and other compatible media. Confirm compatibility with the valve body and VITON seal before use.
4. What is the working pressure range?
See the specification table for this model’s listed working pressure. Confirm the complete system and fittings are rated for the intended pressure.
5. Is an original instruction manual included?
No standalone manufacturer manual or wiring diagram was included with the supplied files. Follow the wiring documentation shipped with the physical valve.
