SELECTOR VALVES

Argonite systems are particularly suited to the use of

selector valves, where one central storage of agent is

used to provide protection to two or more hazard areas.

Selector valves are available in six sizes, and are pneu-

matically operated. One common pressure regulator and

vented elbow are also required to reduce the actuation

pressure to each set of selector valves.

Figure 14. Selector Valve System

Table 9. Selector Valves and Components

NOZZLES

The brass discharge nozzles are available in four basic

sizes 1/2-inch, 3/4-inch, 1-inch and 1-1/2-inch. Each is fit-

ted with a drilled orifice to assure proper flow rates, agent

quality and proper discharge timing as determined by

flow calculations. Maximum nozzle spacing for room

mounted nozzles should not exceed 18.8 feet (5.7 m)

square. Nozzle height should not exceed 16 feet (4.9 m)

from a single layer of nozzles.
