Volumec VALVE POSITION INDICATOR

The valve position indicator VOLUMEC is an interlinking unit with the connection hole pattern for directly controlled NG 06 directional control valves. In detail, the module comprises a valve block, volume counter and display unit. Mounted on a connection plate and completed with a directional control valve, the VOLUMEC is used to control hydraulically operated ship valves for ballast, cargo or stripping systems, to measure and display the adjustment travel of the valve. The control module is designed for installation in deck boxes. The display of the volumetrically detected valve position can be read visually directly on site or electrically via potentiometer or limit switches.
