Information About WT8551A001MS
The WT8551A001MS is part of the ASCO Series 8551 family of pilot-operated spool valves developed for pneumatic actuator control in demanding industrial environments. Its watertight enclosure provides NEMA Type 1, 2, 3, 3S, 4, and 4X protection, making it suitable for indoor and outdoor installations exposed to moisture and washdown conditions. The valve features a compact anodized aluminum body, 1/4-inch NPT ports, and a convertible spool that supports multiple directional control functions depending on the application. With NAMUR direct mounting, manual override capability, and compatibility with air and inert gas, it integrates easily into automated valve and process control systems.
Key Features:
- Series 8551 Design: Engineered for compact pneumatic directional control applications.
- Watertight Enclosure: Provides NEMA Types 1, 2, 3, 3S, 4, and 4X environmental protection.
- NAMUR Mounting: Allows direct installation on quarter-turn pneumatic actuators.
- Convertible Valve Function: Supports 3-way/2-position, 4-way, and 5-way/2-position configurations.
- Pilot-Operated Spool: Combines reliable shifting with long operating life.
- Aluminum Valve Body: Offers lightweight construction with corrosion resistance.
- 120 VAC Operation: Designed for 120 VAC 60 Hz and 110 VAC 50 Hz power supplies.
- Manual Override: Enables manual valve operation during commissioning or maintenance.
The WT8551A001MS delivers the reliability and precision required for pneumatic actuator control and industrial automation systems.
