Visual valve position indication with Proximity explosion-proof position
indicators provides convenience and enhanced safety in valve monitoring.
For
the convenience of the control valve user, a compact, adjustable stainless
steel visual indicator is provided on all direct-drive Proximity position
indicating switches and transmitters. These industrial switches are
commonly mounted on quarter-turn pneumatic actuators and valves. A
magnetic design provides maximum safety by allowing complete sealing
of the switch cavity. Over 2000 specific applications are covered with
an extensive line of mounting kits built for individual valve and actuator
brands and model numbers. As the valve and actuator is cycled, the
input shaft of the position indicator rotates, causing a stainless
steel cylinder to rotate inside a second stainless steel cylinder with
windows. When the valve is open, the word "OPEN" appears in the two
windows located 180° apart. The compact and durable visual indicator
displays discrete endpoints (OPEN or CLOSED) as well as scaled degrees
(0-90). LED and flow path outputs are available options. Up to three
conduit entrances allow utilization of this flexible indicator as a
junction box for additional convenience as well as material and labor
cost reduction to the user.
