SERIES 300

SERIES 300

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.
Model 30U: Up to 375psi working pressure, globe pattern, flanged, grooved & threaded, with drain port.
Model 30CU: Up to 375psi working pressure, globe pattern, double-chamber, flanged, grooved & threaded, with drain port.

UL Listed under the following categories:
  – “Special Systems Water Control Valves” Deluge (VLFT) – Models 30U &
30CU
  – “Fire Pump Pressure Relief Valves” (QXZQ) – Model 30
  – “Special System Water Control Valves, Pressure Reducing and Pressure Control” (VLMT) – Models 30 & 30U
• Lloyd’s type approval
• GOST-R
• Manufacture and conformity assessment of pressure equipment & assemblies Directive (97/23/EC / EN1074)

Consult the UL listing guide or contact OCV Fluid Solutions for a complete list of approved applications and valve sizes.
