Test Stand For Control Valves

Test Stand For Control Valves

Investigation and testing of control valves
Water circuit with tank, pump and connections for control valves
Electromagnetic flow rate sensor
2 pressure sensors to measure the pressure drop over the control valve
Gate valve to adjust the flow rate
Potentiometer to actuate electro-pneumatic valves with a current signal
Pushbuttons to actuate motorised valves
Manometer and pressure regulator to adjust the working pressure for electro-pneumatic valves
Position feedback via current signal (electro-pneumatic valves) or resistance teletransmitter (motorised valves)
