Description
Convalve valve indicator is a rotary position device used to confirm the valve position when mounted to a pneumatic actuator. The visual indicator on top of the device can clearly display the valve position for local detection. Mechanical limit switches provide an electrical signal output to PLC’s or other devices to confirm both the open and closed valve position.
Features
- Multiview visual valve position indicator
- Dual limit switches for remote valve position confirmation
- Standard Namur VDI/VDE-3845 mounting
- Weatherproof Type 4, Nema 4X and IP67 construction
- Polyester powder coated aluminum housing
- Universal mounting bracket included
Applications
Valve monitors (limit switch boxes) are rotary position devices used for both local and remote indication of valve position. Indicators are typi- cally mounted to the top of standard pneumatic rotary actuators via the standard Namur VDI/VDE-3845 mounting pad.
Operation
Output shaft from the air actuator rotates 90º turning the input shaft of the monitor and moving the visual indicator from closed to open (reverses to close). In addition, limit switches provide a dry contact output signal in both the open and closed position. This signal is used to remotely confirm the valve position.
