Overview
The Wabco 572 740 solenoid valve is a directional control solenoid valve designed for pneumatic air flow management across industrial automation and vehicle braking systems. Built by WABCO WESTINGHOUSE, this valve uses solenoid actuation to provide reliable, repeatable control of compressed air pressure and flow. The 572 740 series delivers consistent performance in demanding applications requiring precise pneumatic modulation.
Key Features
- Solenoid-actuated directional control for pneumatic systems
- 5-way, 2-position spool configuration typical in the 572 740 series
- Rated for compressed air media in industrial and vehicle suspension/braking applications
- Compact, durable construction engineered for long-term reliability
- Available in multiple voltage and pressure ratings depending on configuration
