Name: Festo 557771 Proportional pressure control valve VPPE-3-1-1/8-2-010-E1
Brand: Festo

Proportional pressure control valve VPPE-3-1-1/8-2-010-E1

The Festo part number 557771 is an electrical, pilot-controlled diaphragm regulator featuring a 3-way proportional pressure control valve function with a soft sealing principle and mechanical spring reset method. It operates within a DC voltage range of 21.6 V to 26.4 V, offering a 5 mm pressurization nominal width, a 2.5 mm exhaust nominal width, and a normalized nominal flow rate of 310 l/min. This component provides a pressure regulation range of 0.02 bar to 2 bar (0.002 MPa to 0.2 MPa) alongside comprehensive short-circuit and reverse polarity protection for all electrical connections, plus an integrated LED 3-digit display.

Why 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.

Engineering context

Identification and RFQ Guidance

Confirm the exact configuration

Use the manufacturer part number and model code—not appearance alone. Connection, size, material, voltage, pressure, seal, and control options can differ within the same product family.

What to include in your RFQ

Provide quantity, delivery country and ZIP/postal code, required condition, target date, and photographs of the existing nameplate when available.
