Maeda Koki MKTV Type OIL SIGNAL – Flow Indicator with Valve

Optimize your lubrication control with the Maeda Koki MKTV type OIL SIGNAL – Flow Indicator. This dual-purpose device combines the visual measurement capabilities of a tapered flow meter with the precision control of a needle valve. Designed for versatility, it allows operators to visually confirm approximate flow quantities and manually adjust the rate in a single, compact unit. Thanks to its internal spring mechanism, it supports installation in any direction—vertical or horizontal—without compromising performance.

Description

Maeda Koki MKTV Type is engineered for applications that require more than simple flow confirmation. While standard indicators only show if oil is moving, the MKTV series provides actionable data and control.

Visual Flow Measurement The unit features a specialized transparent taper pipe housing a ball (or float) and a distinct indication red line. As oil flows through the tapered section, the float rises against the internal spring. By observing the position of the float relative to the red line, operators can confirm the approximate flow quantity instantly.

Integrated Flow Control What sets the MKTV apart is its flow quantity adjustment valve. Equipped with a miniature valve mechanism, this device allows users to actively regulate the oil supply. By adjusting the valve, you can set the flow quantity to the necessary level, aligning the ball or float with the indication red line for precise operation. This eliminates the need for separate throttling valves in the line.

Flexible Installation Unlike gravity-dependent rotameters, the MKTV utilizes a spring-loaded design that stabilizes the float. This means the installation direction does not matter. The unit functions correctly whether it is attached to look up, look down, or face sideways, offering maximum freedom in piping layout design.

Features

  • It shows flow quantity by viewing. Because use a transparent taper pipe, with a ball (or afloat) and the indication red line. It can confirm approximate flow quantity by looking at the position concerned.
  • With flow quantity adjustment valve. By adjusting a miniature valve a ball (or afloat) at the position of the indication red line. The setting of the flow quantity that is necessary by putting it together is possible.
  • The installation direction does not matter. The posture when attaching it as using a spring inside looks up and look down, and it can perform sideways-facing freely.

Applications

MKTV oil signal is a flow indicator, flow switch, and flow control depending on the type. Confirmation, adjustment is possible with a flow quantity of the oil with lightweight, a compact. With flow quantity adjustment needle valve.
