The Damcos Valve Position Indicator is a precision gear motor with a display indicating the flow of a certain oil volume through the unit. The gear wheels rotate according to flow and flow direction of the fluid. A built-in mini gear box with a gear ratio chosen to suit the actuator displacement in question transfers the gear motor movement to the indicator shaft. There is no mechanical connection between the gear motor and the indicator shaft. The rotary movement of the hydraulic gear wheels is transferred to the indicator shaft by a magnetic clutch.
We can supply Gear Ratios with the following ratio:
100:1, 125:1, 1280:1, 150:1, 25:1, 250:1, 40:1, 50:1, 60:1, 720:1
