Overview
The ASCO 400125-225 solenoid valve is a precision-engineered miniature valve built for the rigorous demands of packaging machinery, pneumatic control systems, and fluid distribution applications. Engineered by ASCO (now part of Emerson), a leader in industrial flow control technology, this direct-operated valve delivers consistent performance across a wide range of operating pressures and configurations.
Key Features
- Direct-operated design eliminates minimum operating pressure requirements
- Compact form factor optimized for packaging machinery integration
- Position-independent operation—mounting orientation does not affect performance
- Precision solenoid actuation for rapid, repeatable valve switching
- Durable construction suitable for continuous industrial duty cycles
- New in box condition—factory sealed and ready for immediate deployment
Technical Specifications
The ASCO 400125-225 provides reliable control across multiple pressure ranges and medium types, from compressed air to light process fluids. Typical miniature solenoid valve specifications for this series include direct-acting spool design, low-power solenoid coils, and standard industrial electrical connectors for straightforward system integration.
