Description

The EVR 100 bench allows the study of the dynamic behavior of a control valve. The bench allows you to calculate the Cv of a valve, know the characteristics of flow rates and to understand the dynamic behavior of the valve.

The unit comes complete ready for use directly usable by the users.

The bench is instrumented with technical and teaching materials in French and all the accessories required for proper operation.

The robust design of this equipment makes it perfectly suited for use in schools.

Its anodized aluminum structure on multidirectional wheels with brakes makes it extremely robust as well as great flexibility of integration into your premises. The manufacturing of this equipment meets the European machine directive

PID Microprocessor controller

Accuracy class: 0.2

Configurable scale range

4-20 mA analog output

Data acquisition software (no license needed)

 Data acquisition, recording and evaluation of the characteristic          of the control valve in order to operate the characteristic curves on PC

The software can be used on a PC computer on which is installed the Windows 7 operating systems

(Or earlier version).

 The cable between the machine and the PC will be provided

  Autonomous water supply:

Polyethylene water tank with draining circuit

Centrifugal pump with stainless steel body

Flow control valve at the outlet

Allowing to simulate functionally the flow of a liquid in an installation   and to illustrate the various phenomena

• Electrical supply : 230Vac – 50 Hz – XX A
• Water supply : 10 L/min – 3 bars
• Compressed air supply: 6-8 bars (dry air)
