Festo
The Festo part number 187744 is a pilot-controlled piston control valve featuring a 3-way proportional pressure control valve closed design with 7 mm nominal width pressurization and exhaust. This electrical component operates on a 24 V DC nominal operating voltage within an 18 V to 30 V range, delivering a 0 bar to 10 bar pressure regulation range at an inlet pressure of 11 bar to 12 bar and a maximum pressure hysteresis of 0.05 bar. Built with soft sealing and integrated short-circuit and reverse polarity protection for all electrical connections, the unit includes a safety function where outlet pressure drops to 0 bar if the power supply cable breaks.
