Bosseal factory is a professional valve manufacturer for Spring Return Ball Valves, or called Deadman Lever Ball Valves.

What is a Deadman Lever Ball Valve?

A deadman valve requires manual operation to open, and it automatically shuts off when the handle is released, due to the action of a spring. Without pressure against the spring, the handle will return to its original closed position.

A deadman valve may also be referred to as a "spring return handle valve".

These valves are used in applications where it is crucial to prevent incorrect operation and ensure the valve remains in the correct open or closed position.

The valve remains in the closed position by default.

The operator must open it by rotating the lever 90 degrees when necessary (spring is stretched).

When the operator releases the handle, the valve returns to the closed position due to the spring action.

Common Issues with Deadman Lever Ball Valves in the Market

In the market, there are many different models of deadman lever ball valves, but there are some common issues that may arise at the job site, potentially leading to human injury or safety accidents.

Disadvantage 1: The lever and stem may lack a fixing nut, which can cause the lever to loosen, potentially injuring the operator and preventing the valve from closing properly.

Disadvantage 2: The bolt that attaches the lever is threaded directly into the valve body, which can compromise the strength of the valve.

Disadvantage 3: The spring in the lever mechanism may blow out, posing a risk of injury to the operator's hand.

Various manufacturers offer deadman lever ball valves, but they may share similar issues that compromise safety and performance.
