Description
The Wilkerson R26-04-000 is a heavy-duty relieving-type air pressure regulator engineered for reliable performance in demanding pneumatic and compressed air systems. Built with a durable zinc body, this regulator delivers precise downstream pressure control while automatically relieving excess pressure when the outlet pressure exceeds the set point — a critical safety feature in sensitive pneumatic circuits.
Key Features
- Relieving-type regulator design automatically vents excess downstream pressure
- Zinc body construction for strength and corrosion resistance
- 1/2″ NPT port size for easy integration into standard compressed air lines
- High 185 SCFM flow capacity to support demanding applications
- Wide adjustable pressure range of 5–125 PSIG for versatile system tuning
- Handles maximum supply pressure up to 300 PSIG
- Two 1/4″ gauge ports for convenient upstream and downstream pressure monitoring
