Description: Pneumatic Pressure Controller, PPC120 is accurate pressure control valve. It is quick in response and cost effective. It is available in 4 control pressure range - 0.15 to 0.9 bar/ 0.6 to 3 bar/ 2 to 9 bar/ 5 to 15 bar. All the materials including sensing below are cast with aluminum and stainless steel and thereby are corrosion resistant. A controlled quantity of air at constant pressure is applied to the controller. The pressure P1 that is set is compared to pressure P2 which is to be controlled. The deviation between P1 and P2 results in the movement of flapper towards or away from the nozzle. This has an effect on output pressure (PO) which is utilized for controlling the pressure to actuator.
