Operating Principle
The Pneumoselect is a Rotary Switch that has a unique “Pull-Twist-Push” mechanism that eliminates the unwanted signals that normally occur with a rotary valve as the head rotated from one selection to the other.
The operating head of the Pneumoselect is pulled out clear of the individual valves as the head is rotated; therefore no unwanted signals are produced. Once the required position is reached the head is pushed home to give the output signal.
