Overview
The ASCO A773871 is a 2/2 normally closed solenoid valve designed for reliable on/off control in pneumatic and hydraulic applications. Built with a bronze body and 3/4″ NPT port connections, this ASCO A773871 solenoid valve handles pressures up to 150 PSI. The 2/2 configuration provides simple inlet-to-outlet flow control with energized opening, making it ideal for bleed-off, pilot control, and general process automation where intermittent or emergency shutoff is required.
Key Features
- 2/2 normally closed (NC) solenoid valve—blocks flow until energized
- 150 PSI maximum working pressure rating
- 3/4″ NPT threaded port connections for easy integration
- Bronze construction for corrosion resistance
- Compact, lightweight design simplifies installation
- New in box condition—fully inspected and ready to deploy

Compatibility & Replacements
Compatible With
- ASCO Numatics manifold blocks and cavity systems
- Pneumatic and hydraulic circuits rated 150 PSI or lower
- 3/4″ NPT port female threaded connections
- Standalone or pilot-operated solenoid valve applications
Replaces / Drop-In Replacement For
Verify compatibility with your system integrator before ordering, as ASCO solenoid valves must match pressure rating, port size, and solenoid voltage to ensure proper fit and function.
Works With
- AC or DC solenoid coils (confirm voltage and frequency requirements)
- Manual override operators for manual control
- ASCO valve manifold systems and cavity mounts
- Standard pneumatic and hydraulic hoses with NPT adapters
