Control Valve Study Bench. 

Control Valve Study Bench Manufacturer
Teaching objectives
  • Determination of the experimental KVS of the valve with and without positioner.
  • Drawing and study of the curves.
  • Intrinsic features of the valve.
  • Qv = f(control) at constant head loss.
Feature of the installed valve :
  • Qv and ΔP = f (control).
  • Function of the positioner and phenomenon of hysteresis.
Functioning
  • A pneumatic servomotor valve is supplied by the water network via a needle control valve. The flow is measured by a rotameter. A regulator allows to adjust the pressure of the network.
  • The difference of pressure between the upstream and downstream of the control valve is measured with the help of a differential pressure transmitter with local display.
  • The influence of the positioner on the answer of the valve is determined with the help of a current generator (4/20 mA) allowing the control of the control valve servomotor via an I/P converter (0,2 to 1 bar) or via a pneumatic electro-positioner.
  • The device is mounted on a welded stainless steel frame, equipped of 4 adjustable feet.
Technical specifiations
  • A regulator 0-3 bar of the water supply circuit with manometer.
  • A needle flow adjusting valve made of stainless steel.
  • A pneumatic needle control valve with variable Cv made of stainless steel.
  • An electro-positioner.
  • A regulator, with air oil separator and manometer.
  • A differential pressure transmitter with local display and bleeding manifold.
  • A rotameter (scale 60 to 600 l/h).
  • An electrical cabinet, IP 55, including .
  • A padlocked main switch.
  • A ON light.
  • An emergency stop button with key.
  • A current generator (4/20 mA) with potentiometer and indicator.
  • Control signal output by safety plugs.
  • Technical manual in English
