3.2 Cylinder Valves (300112 & 302118)
Each cylinder is equipped with a nickel-plated brass valve. The cylinder valves are backpressure type design. A piston in the valve bore is equipped
with a seat seal that keeps the FK-5-1-12 clean agent under pressure within the cylinder. A small hole in the piston allows cylinder pressure to equalize
on both sides of the piston. Since the surface area above the piston is greater than the surface area below the piston, the net force seals the piston
against the primary valve seal. When the pressure above the piston is relieved by any means, there is only cylinder pressure acting against the piston
seal and the piston slides to its fully open position, allowing for agent discharge.
The valve is equipped with a pressure gauge to monitor cylinder pressure and a quarter turn ball valve that interfaces with the Firetrace Detection
Tubing. The ball valve must be kept closed at all times when the cylinder is not in service.
