Maeda Koki MKTV type WATER SIGNAL – Flow indicator with Valve

Maeda Koki MKTV type WATER SIGNAL – Flow indicator is a reliable, high-visibility solution designed for monitoring water circuits in industrial environments. By combining a clear visual flow display with an integrated regulating valve, this unit allows operators to ensure optimal coolant or water supply at a glance. Encased in a durable metal housing, it is built to withstand the physical demands of manufacturing facilities while providing accurate flow verification.

Description

Maeda Koki MKTV type WATER SIGNAL – Flow indicator provides essential data on fluid movement within your piping systems. It functions using a robust variable area principle, where a float ball rises within a transparent taper pipe. When the ball aligns with the distinct indication red line, the operator can visually confirm that the approximate required flow quantity is being delivered to the equipment.

Designed for efficiency and space-saving, the MKTV series eliminates the need for separate flow meters and needle valves by incorporating a flow quantity adjustment valve directly into the unit. This allows for precise throttling and setting of flow rates right at the observation point. To ensure longevity in harsh industrial conditions, the glass components are shielded by a strong metal protective cover, minimizing the risk of breakage from external impacts or accidental shocks. This unit is an ideal choice for maintaining the safety and efficiency of water-cooled machinery and distribution lines.

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 the flow quantity adjustment valve
    By, by adjusting a miniature valve, putting balls together at the position of the indication red line
    The setting of the necessary flow quantity 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 is a flow indicator, flow switch, and flow control depending on the type. It can confirm the approximate flow quality of the water by viewing. With flow quantity adjustment valve.
