ABSTRACT:
A switch mounting arrangement enables close monitoring of seat position in a single-axis double-seat valve. The switch mounting arrangement includes a switch element disposed within a longitudinal bore of a mounting block. The bore also houses a transducer element that is adjustable within the bore to permit relative placement between the switch element and the transducer element so that very slight movement of the switch element and corresponding movement of the valve seat may be detected. This arrangement may then be incorporated into a monitoring circuit and/or control system.
