Product Introduction
Pilot operated pressure control valve by the pilot control valve, pressure sensor and electronic control circuit composition, these parts are integrated in one. The valve is through the pressure sensor and electronic control loop to control the pilot valve opening, drive the spool displacement, so as to achieve the purpose of stable output pressure
Product Advantage
pilot operated pressure control valve has the advantages of high sensitivity, high reliability and good performance.
Product Structure
When the input signal, increased supply in electromagnetic pilot valve reversing superior in working status, and exhaust under electromagnetic pilot valve in working state, then the compressed air from the air supply to the input port P aeration, 7 in pilot chamber through the control valve, pilot chamber pressure rise, promote diaphragm and the valve core moves down, the exhaust valve core shut down,Output outlet A produces output pressure.The output pressure P is fed back to the control loop through the pressure sensor, and is quickly compared and corrected with the target value until the output pressure is proportional to the input signal, so as to obtain the proportional change of the output pressure and the input signal.
