Overview
The Coilhose 8804K regulator is part of the Heavy Duty Series 88 line of pneumatic air regulators. This 1/2″ FNPT port model features a die-cast aluminum body and 0 to 125 psi pressure range, making it ideal for controlling compressed air systems in factories, maintenance shops, and pneumatic tool operations. The balanced poppet valve design maintains precise downstream pressure and the diaphragm stop prevents ruptures in the event of surges.
Key Features
- Tamperproof design prevents unauthorized adjustments, ensuring consistent pressure settings and enhancing system safety
- Balanced design with diaphragm stop to prevent ruptures and maintain stable pressure
- 80 cfpm flow rate capacity
- Relieving design allows excess pressure to vent safely
- Compact die-cast aluminum construction for durability in harsh industrial environments
- Proven, timeless design ensures long, trouble-free service life
