Flow control and valve test bench CVU/EV

Flow control and valve test bench Mod. CVU/EV is a mobile training device for testing various control valves (optional options: CVU-1/EV, CVU-2/EV and CVU-3/EV) and flow control in a closed system equipped with a recirculating pump and storage tank.

The equipment allows you to analyze valve characteristics, determine their operating parameters and practice proportional, integral and derivative (PID) control techniques. Using SCADA software, the system can be monitored and controlled via a Windows computer connected via a serial cable.

Technical characteristics:

• Construction: AISI 304 stainless steel frame with wheels;
• Capacity: AISI 304 stainless steel storage capacity – 70 liters;
• Pump: Centrifugal pump (AISI 304), maximum flow: 80 l/min, maximum head: 22 m H₂O;
• Controls: Electronic microprocessor PID controller with 4-line LCD display and serial card;
• Sensors:
  • 2 pressure sensors (range: 0-2.5 bar);
  • Magnetic induction flow meter made of stainless steel (range: 0–60 l/min);
• Control cabinet: IP55 protection level, including fuse (ELCB) and digital displays for pressure, positioner output and flow readings;
• Other components: Compressed air filter-reducer.

SCADA software:

• Controls on/off and analog signals from the PID controller;
• Allows you to monitor trends and analyze historical data in real time.

Additional options:

• Pneumatic "air-to-open" control valve with positioner and bypass line (mod. CVU-1/EV);
• Pneumatic "air-to-close" control valve with positioner and bypass line (mod. CVU-2/EV);
• Electric control valve with bypass line (mod. CVU-3/EV).

Technical data:

• Power supply: 230 Vac, 50 Hz, single-phase, 1.5 kVA (other voltages and frequencies available upon request);
• Dimensions: 1400 × 600 × 1500 mm;
• Weight: 143 kg.

Educational program:

• Flow and pressure loss measurements;
• Determining the Kv and Cv values of valves;
• Drawing up valve characteristic curves;
• Analysis of the reaction to a sudden change;
• Positioner adjustment;
• Analysis of PID control methods;
• Open and closed loop control studies;
• Controller adjustment techniques;
• System monitoring via SCADA software.
