Maeda Koki MKDV Type OIL SIGNAL – Flow Indicator & Valve

Achieve precision in your lubrication systems with the Maeda Koki MKDV type OIL SIGNAL – Flow Indicator. Designed specifically for low-flow applications, this unit combines visual monitoring with active flow control. It allows operators to confirm minute oil quantities through a clear sight glass while simultaneously regulating the drip rate using an integrated adjustment valve.

Description

Maeda Koki MKDV type OIL SIGNAL is a specialized rheoscope engineered for machinery requiring exact, small-volume lubrication. Unlike standard flow indicators that monitor bulk flow, the MKDV type is “shoryuryosenyo” (exclusive for small flow quantities), making it indispensable for precision engineering contexts.

The device operates by passing oil through a specific nozzle within a transparent housing. This design provides immediate visual feedback, allowing maintenance teams to see the actual dripping situation and confirm the supply of oil even at very low flow rates.

A key advantage of the MKDV model is its dual-functionality. It is equipped with a high-sensitivity flow quantity adjustment valve. This allows users to manually fine-tune the dripping speed, ensuring that the machinery receives the exact amount of lubricant required—no more, no less. This feature is critical for preventing both oil starvation and wastage in sensitive equipment.

Features

  • For Small Flow Rate Only type
    On seeing the dripping situation dropped by the nozzle which supply of the oil gained in the transparence jurisdiction, it can confirm a flow of little flow quantity.
  • With flow quantity adjustment valve
    A very small amount of dripping adjustment of the oil is possible.

Applications

MKDV oil signal is a flow indicator, flow switch, and flow control depending on the type. It can visually confirm for Small Flow Rate Only in the dripping situation. With flow quantity adjustment valve
