Festo
The Festo 542248 is a pilot-controlled diaphragm regulator featuring a 3-way proportional pressure control valve with electrical actuation and soft sealing principles. It operates within a pressure regulation range of 0.02 bar to 2 bar (0.002 MPa to 0.2 MPa), an inlet pressure of 0 bar to 4 bar (0 MPa to 0.4 MPa), and delivers a normal nominal flow rate of 380 l/min at a DC operating voltage range of 21.6 V to 26.4 V. This component includes LED display indication, mechanical spring reset, any mounting position, a 6 mm nominal width pressurization, a 4.5 mm exhaust nominal width, a max pressure hysteresis of 0.01 bar, and comprehensive short-circuit and reverse polarity protection for all electrical connections while maintaining outlet pressure in uncontrolled form if the supply cable breaks.
