Actuation Spring Return Handle
A spring return 'dead man handle' for mounting on ball and butterfly valves (used mainly on ball valves). The handle is turned by the operator but as soon as the grip is released it springs back to its resting position. Please note that the above choice is to suit our ball valves. If you are fitting it on another brand please look at the dimensions page to make sure what you are buying is correct. Different valves can have different mounting pads and drive sizes.

What is a Valve Dead Man Handle?
A dead man handle is designed to mount on a 90 degree turn valve (usually a ball or butterfly valve) that will return the valve to a resting position when the user takes their hand off the handle.
-
How does a Dead Man Handle work?
The valve is operated as per a normal handle where the user will turn it 90 degrees to operate the valve. The handle itself contains a spring within it that provides the torque needed to open or close the valve (depending upon which way you set it up).
-
How long will my Dead Man Handle last?
The spring within the valve handle will fatigue over time however this will take a very long time. More than likely the valve it is operating will wear out before the handle.
-
How do I install a Dead Man Handle on a valve?
It is easiest to install and test this on your valve before it is installed in the line as you can make sure it has enough torque to fully close or open the valve. For mounting instructions it is probably best to view our video on mounting as there are a few steps and tips that are best viewed.
-
What are typical uses of a Dead Man Handle?
These are used in any application where a resting position valve is needed as a matter of safety. This could be that when the operator lets go of a valve handle after operation the valve will automatically return to a pre determined position (open or close).
-
How long will my product take to get to me?
This depends upon where you are based and the freight method chosen. If the express freight option is selected it is usually next day delivery to metropolitan areas in Australia for under 5kg. If free freight has been selected it will go by road freight which can be anywhere from 1 to 10 days depending upon your location. It usually averages 3 days.

What warranty do I get?
All of our products come standard with a 12 month warranty. The good news is we have very strict quality controls and all valves leave our warehouse tested (full material and testing certificates to API598 are available) and inspected so there are rarely any issues. Also once your valve is in and operating it will most likely continue to do so for a very long time.
