Pumps/Valves/Fittings Test Stand Model MT 26

* Plotting characteristics of industrial valves and fittings1
* Comparison of different valves and fittings1
* Characteristics of a centrifugal pump

Item Description

Sci-tech Pumps/Valves/Fittings Test Stand Model MT 026 allows the characteristics of different valves and
fittings to be compared. The typical kinds of valves and fittings are represented by a ball valve, a butterfly valve,
two gate valves and a control valve. A safety valve and a dirt trap are also investigated. All valves and fittings
are flanged, and can be installed in a pipe section with variable length. The pipe section is part of a closed
water circuit. Pressure measurement points upstream and downstream of the valve and fitting under test are
linked by a differential pressure manometer. This manometer is fitted with a pressure switch which activates a
warning lamp if the pressure difference becomes excessive, such as when the filter is clogged. An
electromagnetic flow rate sensor permits precise recording of the flow rates.
