The Festo 542211 is a pilot-actuated diaphragm regulator featuring a 3-way proportional-pressure function with a 6 mm nominal pressurization diameter and a 4.5 mm exhaust diameter. Operating on a 21.6 to 26.4 V DC voltage range with a 100 percent duty cycle and 7 W max electrical consumption, this electrically actuated unit delivers a 380 l/min standard nominal flow rate across a 0.02 to 2 bar pressure control range. It incorporates short circuit and polarity protection for all electrical connections, a soft sealing principle, mechanical spring reset, and an LED display.
