We designed these valves specifically for level gauges and offer a wide lineup, ranging from low to high pressure, to meet diverse needs.

Safety

• The built-in ball valve blocks fluid from blowing out, even if the gauge glass gets damaged.

Functionality

• For medium and high pressure, the spindle does not rotate when opening and closing the valve, the handle operation is light, and the valve seat does not seize.
• The lower gauge valve is equipped with a drain valve as standard equipment.

Diversity

• With support for various materials, you can choose the optimal valve based on the level gauge specifications.
• Flanges, taper screws, welding sockets, etc. are available for connection.

Notes

• Opening the handle too quickly can activate the ball valve, so turn it slowly.

Structure and operation of two-color water level gauge

The dual-color level gauge utilizes optical principles and is configured so that steam appears red and water appears blue. The structure is such that when the light passes through a trapezoidal water chamber made up of two gauge glasses, the light is refracted by the glass and the red filter glass is visible when the water chamber is steam. Conversely, if there is water in the water chamber, the light will be refracted by the gauge glass and the water to see the blue filter glass.

Visibility

• Since the liquid level is displayed separately in two colors (red and blue), the liquid level can be clearly seen.
• Suitable for visual monitoring and remote TV monitoring.

Diversity

• If you want to increase the visible length, you can arrange the level gauges alternately on the left and right.

Notes: It is not possible to check the two-color display depending on the position or angle when checking the liquid level.
