Festo
557774
Proportional pressure control valve VPPE-3-1-1/8-2-420-E1
The Festo 557774 is a pilot-controlled diaphragm regulator featuring a 3-way proportional pressure control valve with a 5 mm nominal pressurization width and a 2.5 mm exhaust nominal width. This electrical actuation component operates within a DC voltage range of 21.6 V to 26.4 V, incorporating short-circuit and reverse polarity protection across all electrical connections, a 3-digit LED indicator display, and a mechanical spring reset method. It delivers a pressure regulation range of 0.02 bar to 2 bar at inlet pressures between 3 bar and 4 bar, achieving a normal nominal flow rate of 310 l/min with a maximum pressure hysteresis of 0.02 bar.

Request a QuoteWhy no listed price?
Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
