What provides remote emergency operations to main drainage system valves?

• A. Remote Control Panel
• B. SCADA System
• C. Manual Valve Controller
• D. MVHC

Answer: (D)

Remote emergency valve actuation needs a device that can move the valve from a distance when time and accessibility are critical. The Motorized Valve Hydraulic Controller delivers that function by providing the hydraulic power and control signals to position the main drainage system valve remotely. It converts electrical control commands into hydraulic motion to open or close the valve as needed during an emergency, ensuring fast isolation of portions of the drainage system. A remote control panel is just the interface to send commands; SCADA is supervisory and may coordinate actions but does not directly actuate the valve; a manual valve controller requires someone on the spot to operate it. So the MVHC is the component that actually provides remote emergency operation for the valves.
