Festo
161177
Proportional pressure control valve MPPE-3-1/2-10-420-B
The Festo 161177 is a pilot-controlled piston control valve featuring a 3-way proportional pressure control function with a closed configuration, soft sealing principle, and an 11 mm nominal width pressurization alongside a 12 mm exhaust nominal width. This electrical component operates within a DC operating voltage range of 18 V to 30 V utilizing a 10 V reference voltage, incorporating short-circuit and reverse polarity protection across all electrical connections, plus a safety position that maintains outlet pressure in an uncontrolled form if the supply cable breaks. It supports an operating pressure up to 1.2 MPa (12 bar), an inlet pressure range of 1.1 MPa to 1.2 MPa (11 bar to 12 bar), and a pressure regulation range from 0 MPa to 1 MPa (0 bar to 10 bar) with a maximum pressure hysteresis of 0.005 MPa (0.05 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.
