SERIES 100

Fire Protection

SERIES 100

The OCV Series 100 control valves are automatic, hydraulically actuated, direct diaphragm sealing globe/weir type valves with a proven and reliable design. These valves are designed for use in fire protection applications including deluge, pre-action, pressure relief, monitors, hydrants and are suitable for water, foam and seawater systems. The valves consist of three major components: body, cover and diaphragm assembly.

UL Listed basic untrimmed valve models: 44, 68, 77

Model 44: Up to 230psi working pressure, threaded.
Model 68: Up to 375psi working pressure, flanged & grooved with drain port.
Model 77: Up to 230psi working pressure, flanged & grooved.
