ASCO 8551A117 Valve
The ASCO 8551A117 Valve is a high-performance pneumatic spool valve engineered for precise fluid and gas control in demanding industrial environments. This 5/2-Way pilot operated valve features a robust brass body and a stainless steel spool, ensuring superior durability and resistance to corrosive conditions. Designed with a 1/4" NPT pilot connection, the ASCO 8551A117 integrates a unique sealing system that combines hard T-seals and flexible o-rings to provide bubble-tight shutoff and a multimillion-cycle service life. Its compact design allows for seamless installation in space-constrained applications, while the integrated NAMUR interface enables direct mounting to actuators. Ideal for process control, robotics, and HVACR systems, this valve operates efficiently across a pressure range from vacuum to 125 PSI. By replacing the B551A117 model, it offers a reliable solution for modernizing pneumatic circuits with advanced pilot-operated spool valve technology.
Key Benefits:- Corrosion Resistance: Durable brass and stainless steel construction for harsh environments.
- Operational Versatility: Convertible design suitable for both 3/2 and 5/2 flow configurations.
- Actuator Compatibility: Features a standard NAMUR mount for easy integration with industrial actuators.
- Extended Lifecycle: Advanced T-seal design provides resistance to dirt and frequent cycling.
- Manual Override: Includes a manual override for simplified troubleshooting and maintenance.
- What are the primary applications for the ASCO 8551A117? It is widely used in industrial automation, chemical processing, and HVACR pneumatic systems.
- Can this valve handle vacuum applications? Yes, it is rated for a pressure range from vacuum up to 125 PSI.
- Is the NAMUR interface standard? This model is designed specifically to mount directly to actuators with a NAMUR interface per VDI/VDE 3845.
