SYSTEM CONTROLS AND INDICATORS

2-2.1

General

Compressed HFC-227ea liquid is held in the cylinder by a discharge valve. When the discharge
valve is actuated by a control head, the valve piston is displaced and the compressed liquid
escapes through the discharge port of the valve and is directed through the distribution piping
to the nozzles. The nozzles provide the proper flow rate and distribution of HFC-227ea.
