FMI flow valve position indicator

Ⅰ.Product introduction

The FMI valve position indicator is a combination unit with mounting surface for directional control valves ∮6 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 a directional control valve，the FMI valve enables to control hydraulic operating ship armatures for ballast, cargo-and stripping systems of all kind of tankers. In addition to that the adjusting path of the armature will be measured and displayed. The valve position indicator is suitable for the installation into deck boxes. The indication of the volumetric entered armature position can be read off optically locally or can be taken electrically by potentio meters or open/closed switches.

Ⅶ.   Remarks

1.The hydraulic oil flow into FMI valve position display should not be too fast (FMI04 type should be less than 6L/min.,FMI08 type should be less than 7L/min.), or it will affect the display accuracy of FMI valve position display. The working flow of hydraulic oil can be

adjusted by adjusting the speed regulating valve on the hydraulic valve block.

2.Normal hydraulic oil is suitable for this valve position display, the normal oil temperature should be controlled in -20 ℃ ~ + 80 ℃.

3.On the FMI valve position indicator using the tubular connection valve block, the direction of the pressure oil enters from the IN port and exits from the OUT port, and cannot be connected in the opposite direction. In addition, port T must be connected to the tank and submerged below the liquid level.
