WHEN THE POSITIONER IS PURCHASED MOUNTED ON OMAL S.P.A. PNEUMATIC ACTUATOR, YOU WILL RECEIVE IT ALREADY CALIBRATED; OTHERWISE THE SETTING IS UP TO THE CUSTOMER. OMAL S.P.A. WILL NOT BE RESPONSIBLE FOR IT.
DESCRIPTION Cam pneumatic positioner is particularly suitable for proportional working of both DA and SR actuators. This positioner is connected with the actuator by means of a mounting kit fixed to the actuator. A regulating pneumatic signal, given by a thermostat, viscometer, pressure gauge, etc. ..., is sent to the positioner which, according to this signal, regulates the valve opening and closing angles. Clockwise and anticlockwise actions can be changed without using additional components, but simply turning the cam over and reverting the actuator connections.
TECHNICAL FEATURES - Supply:dry instrument air 5μ - Regulating signal pressure: 0,02 - 0,1 MPa (0,2÷1 bar) (3÷15psi) - 3 manometers: 2 for air supply, 1 control signal. - Pneumatic connections: 1/4” NPT - Input signal connection: 1/4” (thread) - Protection: IP65 (according to IEC Pub.60529) - Sensitivity: <0,5% of the range - Linearity: < ±2% - Air consumption: from 5 Nl/min.(P=1,4 bar) to 11 Nl/min.(P=4 bar) - Working temperature: from -20°C to +80°C - Available on request: high temperature (-5°C / +100°C), low temperature (-30°C / +60°C)

NOTES Pneumatic and electro-pneumatic positioners are supplied up on request adjusted and are mounted using covered aluminium pipes and rapid connectors.
Adjustment A = 0° - 90°: • 0,2 bar control pressure: closed position • 1 bar control pressure: opened position. Adjustment D = 90° - 0°: • 0,2 bar control pressure: opened position • 1 bar control pressure: closed position.
