The cylinder valves are back pressure type valves.
A piston in the valve is equipped with a rubber seal that keeps the HFC-227ea Clean Agent under pressure within the cylinder.
A small hole in the piston allows cylinder pressure to be equalized on both sides of the piston.
Since the area at the top of the piston is greater than the area at the bottom of the piston, the net force seals the piston against the valve discharge outlet.
When the cylinder pressure on the top of the piston is relieved by means of automatic or manual actuation, there is only cylinder pressure acting against the piston seal, and the piston slides to its full open position, allowing cylinder discharge through the distribution network.
Luke offers valves in two materials, Stainless Steel and Brass.
The functions of both valves are identical.
