VALVE MONITOR

The Convalve valve gauge is a rotary position device used to verify valve position when mounted on a pneumatic actuator. The visual indicator on the top of the device can clearly display the valve position for local detection. Mechanical limit switches provide electrical signal output to PLCs or other devices to verify both open and closed valve position. Features Multiview visual valve position indication 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 body Universal mounting bracket included Applications Valve monitors (limit switch boxes) are rotary position devices used for both local and remote indication of valve position. Gauges are typically mounted on top of standard pneumatic rotary actuators with the standard Namur VDI / VDE-3845 mounting pad. Operation The output shaft of the air actuator rotates the monitor's input shaft 90º and moves the visual indicator from closed to open (reverses to close). In addition, limit switches provide a dry contact output signal in both open and closed positions. This signal is used to remotely verify the valve's position.
