Festo
8181691
Proportional-pressure control valve VPPE-3-1-1/4-10-MR-E1-F1A
The Festo 8181691 is a pilot-controlled diaphragm regulator featuring a 3-way proportional pressure control valve with electrical actuation and a soft sealing principle. It offers a pressure regulation range of 0.01 MPa to 1 MPa (0.1 bar to 10 bar), a 5 mm nominal width pressurization, a 2.5 mm exhaust nominal width, and supports an inlet pressure 1 of 6 bar to 11 bar with digital setpoint input displayed via an LED 3-digit indicator. This component includes short-circuit and reverse polarity protection for all electrical connections, a mechanical spring reset method, and maintains outlet pressure in uncontrolled form if the supply cable breaks according to VPPE safety position instructions.

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.
