Description
The pneumatic actuator assembly (p/n C70-233) provides a pneumatic means of discharging the CO2 system when an automatic detection and control system is not desired. The assembly consists of a machined brass valve, stainless steel lever mechanism, and a spun steel container finished with red gloss, baked enamel paint. The pneumatic actuator includes a pressure gauge to monitor the nitrogen pressure in the cylinder, and a safety relief device that will rupture if the pressure in the cylinder rises to 2,650 – 3,000 psi (18,270 – 20,685 kPa) per NFPA 12.
