Festo
The Festo 542246 is a pilot-controlled diaphragm regulator functioning as a 3-way proportional pressure control valve with electrical actuation and a soft sealing principle. It delivers a normal nominal flow rate of 900 l/min across a pressure regulation range of 0.06 bar to 6 bar, operating on a DC voltage range of 21.6 V to 26.4 V with built-in short-circuit and reverse polarity protection. Featuring a 6 mm nominal pressurization width and a 4.5 mm exhaust nominal width, this unit includes an LED display and maintains uncontrolled outlet pressure if the supply cable breaks.
