Festo
The Festo 558342 is a pilot-controlled diaphragm regulator featuring a 3-way proportional pressure control valve with electrical actuation and a soft sealing principle. It provides a pressure regulation range of 0.01 MPa to 1 MPa (0.1 bar to 10 bar), an inlet pressure range of 0 bar to 11 bar, a nominal pressurization width of 6 mm, an exhaust nominal width of 4.5 mm, and a normal nominal flow rate of 1400 l/min at a DC operating voltage range of 21.6 V to 26.4 V. Additional technical features include a backlit LCD display, mechanical spring reset, piloted control, and integrated short-circuit and reverse polarity protection for all electrical connections, while operating under safety instructions where a supply cable break maintains the outlet pressure in an uncontrolled form in any mounting position with a maximum pressure hysteresis of 0.05 bar.
