Why Choose a Valve with a Deadman Handle?

Otherwise known as a spring return handle, a deadman handle on a valve serves a specific purpose. Without it, tasks like drawing a media from a drum or tank; introducing an addition to a media; or performing any job that demands that an unattended valve must not be left open would be rather difficult. A deadman handle makes it easy.

What is a Deadman Handle?

While the true origin of the moniker, deadman handle, may be impossible to trace, its meaning is quite simple. Another name was, deadman switch. Basically this morbid joke meant that if an operator were to suddenly die, the switch or handle would move automatically, in spite of tragedy. In this way, a valve--let's use a ball valve--equipped with a deadman handle, will automatically shut itself off when you let go of the handle. This is due to spring action. Without the pressure against the spring, the handle will return to its original position.

This is a must have in any shop or factory, and has a virtually endless list of possible applications. While they all perform the same task, there are different models available.  The following are just a few examples.
