The Valve Position Indicator VOLUMEC is a combinationunit with mounting surface for directional control valvesNG 06 according to ISO 4401-03-02-0-02/DIN 24340-A6.In detail the module consists of a hydraulic manifold,a gear type volume counter and an indicator.
Mounted on a connection plate and completed by adirectional control valve the VOLUMEC enables to control hydraulic operating ship armatures for ballast-, cargo- and stripping systems of all kind oftankers. In addition to that the adjusting path of thearmature will be measured and displayed.
The Valve Position Indicator is suitable for the installa-tion into deck boxes. The indication of the volumetricentered armature position can be readoff optically locally or can be taken electrically bypotentiometers or open / closed switches.

Function
Together with the gear type volume counter the indicator builds the measuring unit. The turning of thegear wheels is transferred via a magnetic drive to thegear box of the indicator. For each application theturndown ratio of the gear box is configurated to geta pointer movement of approx. 180°. The pointer islimited by two end stops. To reset the indication ateach end position a slipping clutch is integrated.The driving shaft of the magnetic drive is equippedwith a small indication to recognize the movement ofthe gear wheels. It can be used as leakage detection.
The indicator is completely separated from thehydraulic circuit. The housing of the indicator consistsof seawater resistant aluminium, all fixing materialsare made of A2.

Explosion-Proof Design (ATEX)
Function
• VOLUTRONIC ® Valve Position Measuring Instrumentand switch amplifier are connected electrically witheach other. The switch amplifier evaluates the sensorsignals of the Valve Position Measuring Instrumentand converts them into square-wave signals.
• Without switch amplifier the VOLUTRONIC ® ValvePosition Measuring Instrument may be pursued notin the explosion-threatened area.
• Between Valve Position Measuring Instrument andswitch amplifier cable lengths to 400 m are possible.
• In the switch amplifier are LED's to the control of manage-ment break/short circuit, canal-switch state and tension care.
• The explosion-protected execution passes of theVOLUTRONIC ® Valve Position Measuring InstrumentVC 0.2 P1 PX-ATEX (own-sure electric equipment)and the switch amplifier K 130 (accompanyingelectric equipment). To this construction countsthe type of protection ”intrinsic safety”.
• The VOLUTRONIC ® Valve Position MeasuringInstrument is installed in the explosion-threatenedarea.
• The assembly of the switch amplifier K 130 occursin the sure area.
