Can the motorized water valve be manually closed?

In water treatment systems, industrial automation, and other fields, motorized water valves are becoming increasingly important. Many valve purchasers ask during selection: Can motorized water valves be manually closed? What should we do if we encounter an emergency power outage? This article will help you easily choose a motorized water valve with a manual reset function.

 

 

 

 

What is a motorized water valve, and why is a manual shut-off function necessary?

Motorized water valves are ball valves driven by electric motors. Unlike manual ball valves, they support remote control, angle modulation, signal feedback, and other functions.

However, in real-world operating conditions, emergency power outages, malfunctions, or signal interference can occur. In such situations, the manual shutdown function effectively prevents hazards and minimizes economic losses.

According to Jinfeng Valve's latest product data for 2025, 70%-85% of motorized water valves are equipped with manual operation capabilities.

 

Common Manual Operation Methods for Motorized Ball Valves

1. Pull & Turn Knob

Commonly found on household miniature smart ball valves

Operation Steps: Pull the knob on the valve actuator, rotate it to the “Close” position, then push the knob back into place.

Advantages: Simple operation requiring no additional tools; manually closes the valve in seconds.

2. Hex Wrench or Lever

Common in industrial-grade motorized ball valves (requiring higher torque operation)

Operation: Insert the included hex wrench into the side hole and rotate to close the valve.

Advantages: Suitable for industrial-grade large-diameter valves.

3. Capacitor Return + Manual

Valves can be equipped with automatic power-off shut-off functionality.

 

Advantages and Disadvantages of Manual Functions in Motorized Valves

Advantages:

Enhanced Safety: Prevents hazards caused by malfunctions and eliminates concerns about water leakage during power outages.

Simplified Maintenance: Operations can be performed without disassembling the valve.

Disadvantages:

Requires Regular Inspection: Prolonged disuse of the manual function may cause the handle to become stiff or jammed.

 

Conclusion

Can motorized water valves be manually shut off? The answer is yes.

Valve procurement can opt for motorized ball valves with manual override for added safety assurance.

FAQ

1. Do all motorized water valves come with a manual shut-off function?

No, but most products can be equipped with this feature. When purchasing, check the description for “manual override.”

2. Will a motorized water valve automatically close after a power outage?

To enable automatic closure after power loss, an additional capacitor module must be added to the actuator for power-fail reset functionality. Otherwise, manual operation is required.

3. Which manual override motorized ball valve is the best choice for 2025?

Jinfeng Valve's stainless steel series offers superior sealing, corrosion resistance, and straightforward operation.
