77MO/RC Hydraulically / Pneumatically Controlled Monitor Valve

The hydraulically / pneumatically controlled monitor valve is designed for fire protection systems, particularly the supply lines to fire monitors, where water flow must be managed remotely or through a controlled operating sequence. The 77MO/RC provides faster, more controlled operation and supports system integration compared with manual operation. By controlling the water supply to the monitor line, it reduces operator workload during a fire and simplifies system management. Typical applications include industrial facilities, tank farms, filling areas, ports and high-flow fire protection systems. The 77MO/RC has a GGG50 ductile iron body designed for heavy-duty conditions. Flanged connections provide secure installation in fire protection piping. Its maximum operating pressure is 300 psi / 21 bar, with a maximum operating temperature of 80°C. It provides a professional solution for monitor applications requiring remote on/off operation or sequence-based control.
