Spring return handles for instrumentation ball valves protect personnel and environment from sample waste, this is particularly required for sampling valves. Function is spring return to closed position when the handle will be released. The spring return handles also known as “deadmans” handles, the function in this case is always that the valve is (spring) return to closed position when the handle will be released.
Panel Mounting
All models Mechatest spring return handle can be used as panel mounting.
Panel hole: 22,5 mm (diameter)
Panel thickness: max. 7 mm
Failsafe Operation
It often happens that manual operated instrumentation ball-valves are not turned in the required position after operation. Most times this means that the valve is not closed. It can be very important (for safety reasons) that the ball-valve automatically rotates back in close position. This can be achieved by mounting a spring return adapter on top of a manually operated ball-valve.
For this purpose Mechatest designed two spring return handle adapters, one with 90° rotation for 2-way ball-valves and one with 180° rotation for 3-way ball-valves.
The Mechatest spring return handle can directly mounted to several types Swagelok, Fitok and Hoke instrumentation ball-valves, check in our webshop all other possibilities.
Applications
Effectively dealing with the effluent and waste from sample taps is a concern to both environmental and safety engineers at petrochemical plants.
The Mechatest spring return handle guarantee failsafe operation for small instrumentation ball valves with automatic (spring) return to closed position.
The spring return handle with ball-valve is the perfect solution for the most common lab sample points.
