1. A valve drive system comprising:
- a valve drive device having a pneumatic actuator including a pneumatic cylinder and a piston moveable within the cylinder;
a hand-operated apparatus to trigger control actions in the valve drive device, wherein the hand-operated apparatus includes a magnet arrangement, and wherein a magnetic field generated by the magnet arrangement in the hand-operated apparatus triggers the control actions in the valve drive device in a contactless manner;
wherein the valve drive device includes a magnetic field sensor arrangement located within a housing of the valve drive device and adjusted to the magnet arrangement of the hand-operated apparatus; and
wherein the hand-operated apparatus causes signals to be generated in the valve drive device, with each signal having an associated valve command to trigger a corresponding operation of the valve drive device.

17. A valve drive system comprising:
-
a valve drive device having a first housing associated with a pneumatic actuator that includes a pneumatic cylinder and a piston moveable within the cylinder; a hand-operated apparatus to communicate with the valve drive device in a contactless manner, wherein the hand-operated apparatus includes a magnet arrangement received within a second housing that is separate from the first housing; wherein the valve drive device includes a magnetic field sensor arrangement located within the first housing, the magnetic field sensor arrangement being responsive to the magnet arrangement of the hand-operated apparatus in a contactless manner; and wherein the interaction between the magnetic arrangement and the magnetic field senor arrangement causes signals to be generated in the valve drive device, with each signal having an associated valve command to trigger a corresponding operation of the valve drive device. - View Dependent Claims (18, 19, 20)
