Humphrey expanded the ProControl family with the addition of the ProControl Pressure Regulator Series. These electronic pressure regulators provide outstanding performance, versatility and value. Designed for low volume flow rates (PCRL) or high volume flow rates (PCRH), ProControl regulators precisely sustain outlet pressure, even during dynamic changes in downstream flow rates.
Their new ProControl Valve Series provides variable flow proportional to the amount of current applied to the solenoid. Miniature PC3 is ideal for precise control up to 24 litres per minute flow, while the small PC10 controls up to 65 litres per minute. The newest addition, the large PC30, controls up to 300 litres per minute. The inert construction of both valves makes them an ideal choice for many types of compressible media.
