Fail Safe Close Manual Ball Valves

Have you ever experienced a valve malfunction, leading to costly downtime and repairs? Valves play a critical role in controlling fluid flow in industrial processes, making valve failures a major concern for many industries.

What is the Difference Between a Fail-Safe Close Manual Ball Valve and a Standard Manual Ball Valve?

A fail-safe close manual ball valve and a standard manual ball valve may look similar, but they have significant differences in functionality.

A fail-safe close valve features a spring return handle that is designed to automatically shut off the flow of liquid or gas when the handle is released. These valves are also commonly referred to as a dead man’s handle and spring return lever valves. This ensures that the system remains safe and prevents damage or accidents.

On the other hand, a standard manual ball valve must be manually turned off by an operator. This means that in the event of an emergency, the valve may not be shut off in time, leading to potential hazards or damage.

Why Use a Fail-Safe Close Manual Ball Valve?

When it comes to controlling the flow of fluids and gases, safety should always be a top priority. That’s why fail-safe close manual ball valves are so important.

These valves are designed with a fail-safe mechanism that ensures the valve will close automatically when the handle is released by the operator. This can prevent dangerous leaks, spills, and other hazards that could cause harm to people or the environment.

Where Would a Fail-Safe Close Manual Ball Valve be Used?

A fail-safe close manual ball valve is typically used in applications where safety is paramount.

Some typical uses of this product are:

  • A drain or sampling valve must have the ability to return to the closed position after being released, particularly when installed in a tank, in order to prevent product waste if left open.
  • It is important to isolate critical processes, such as diesel filling lines, to avoid potential disasters caused by leaving them in the open position.


In conclusion, investing in fail-safe close manual ball valves is a smart decision for any industrial operation. With their reliable performance and ability to prevent costly accidents, these valves offer peace of mind and protection for both your equipment and your employees.
