APC 318 Control Valve Characteristics

Stand alone, for understanding the control valve operation and its flow characteristics. Pneumatic control valves of linear type, stainless steel water tank with water circulation and rotameter for flow measurement. Pressure measured at valve inlet (mm water) Air regulator and pressure gauge for control valve actuation.

Experiments range:

• valve flow coefficient
• inherent characteristics
• installed characteristics
• hysteresis of control valve
• rangeability of equal percent control valve
• valve positioner
