Elesa+Ganter 111346 HVF.114-1 NPT Visual Flow Indicator

Technical Overview

The Elesa+Ganter 111346 visual flow indicator, known as HVF.114-1 NPT, is a visual flow monitoring component with a 1 NPT conical gas thread according to ANSI-ASME B1-20. It is designed for applications where operators need to confirm liquid movement directly through the indicator body. The model belongs to the HVF range and is suitable for two-way liquid flow.

Construction Details

The HVF.114-1 NPT uses polypropylene-based technopolymer ends, a red polypropylene rotor propeller, a high-resistance borosilicate glass tubular window, and AISI 316L stainless steel tie rods. The standard HVF execution includes brass bosses and NBR synthetic rubber gasket. The borosilicate glass window provides wide-angle flow visibility, which is valuable during inspection and routine maintenance.

Technical Performance

This model has a 1 NPT thread, 114 mm height, 70 mm length, 46 mm h1 dimension, and a maximum flow rate of 80 l/min. The maximum pressure is 12 bar. The minimum flow rate needed to start rotor movement is 2.1 l/min for water, 3.7 l/min for fluids between 0 and 40 cSt, and 5 l/min for fluids between 41 and 150 cSt. Its pressure drop is 0.15 bar.

Where It Is Used

The Elesa+Ganter 111346 HVF.114-1 NPT visual flow indicator is commonly used in hydraulic machinery, process lines, lubrication systems, and cooling installations where NPT threaded connections are preferred. It can be mounted in any position, but rigid pipe systems should be carefully aligned to prevent unnecessary stress. For more information about Elesa+Ganter components, visit Elesa+Ganter.

Elesa+Ganter 111346 FAQ

What does NPT mean on HVF.114-1 NPT?

NPT refers to a conical pipe thread standard commonly used in industrial fluid systems.

Is this model suitable for bidirectional flow?

Yes. The indicator operates with two-way liquid flows.

What is the maximum pressure rating?

The maximum pressure rating is 12 bar.

Does it provide electronic output?

No. This is a visual flow indicator, not the sensor-equipped HVF-E version.
