Festo
The Festo 8104664 is a 3-way proportional pressure control valve featuring a poppet valve structural design with spring return and an operating pressure range of 6 bar to 8 bar. This directly controlled electrical component provides a 5 mm nominal width for both pressurization and exhaust, a soft sealing principle, and a total leakage of 5 l/h with non-reversible flow direction. Equipped with LED display, mechanical spring reset, and a 100 kOhm input resistance, it accepts setpoint inputs of 0 - 10 V or PWM while incorporating short-circuit and reverse polarity protection for all electrical connections alongside a safe normally closed VPPI position. Measuring 42.2 mm in width, 95.3 mm in length, and 94.3 mm in height with a maximum cable length of 30 m, it supports mounting in any position.
