Fire Protection Basic Valves MODELS 30 30U 30CU
The Series 300 control valves are automatic, hydraulically actuated, diaphragm operated, rigid seal globe pattern control valves. These valves are designed for use in fire protection applications, including deluge, pre-action, pressure control, monitors, hydrants and are suitable for water, foam and seawater systems. The valves consist of three major components: body, cover, and internal trim assembly.
UL Listed Basic Untrimmed Valve Models: 30, 30U, 30CU
Model 30: Up to 375psi working pressure, globe pattern, flanged, grooved & threaded.
