The Position-Feed-Back Shaft, projected at the top of the valve, moves up and down as the valve opens and closes. The shaft can transmit the motion of the valve to a microswitch for sending a reliable feedback signal of the on-off status to the control system.

Effectively, by feeding back the valve motion itself, the Position-Feed-Back Shaft enhances the reliability by constant monitoring the valve status in comparison with traditional methods monitoring an electrical current sent to the valve. Highly recommended for reliability-oriented applications.
