2. Application

The VR51 is a valve designed to be operated by both hands simultaneously at the startup of an
actuator through button operation to ensure the safety of the worker.
As the worker uses both hands in operation of the start button, it is possible to prevent accidents
including pinching of hands in a work process.

3. Features

1) If the difference in input timings (time of devices to be operated) between two air signals is 0.5
seconds or longer, there will not be an output.
2) If one air signal input is lost while VR51 is performing output, the output will be stopped.
3) To resume the output, it is necessary to simultaneously input two air signals again.
4) VR51 is compliant with Category 1, Type III A of the European Standards [Safety of machinery --
Two-hand control devices -- Principles for design and selection] (CE/UKCA MARKED EN
ISO13851:2019).
