Product features

Standard (classic) Venturi tube is designed and manufactured according to the national standard GB/T2624, according to the national standard JJG640 verification standard throttle device, no calibration.

In the standard throttle device, it requires the shortest upstream and downstream straight pipe segments and the minimum permanent pressure loss.

Stable performance and high reliability.

The calculation is accurate and the energy consumption is low.

It can be used in a variety of dirty media such as liquids, gases, steam and two-phase flow.

Simple structure, easy to install, easy to maintain.

The standard venturi body is about 2 to 5 times longer than the tube diameter.
