Festo
571448
Proportional pressure control valve VPPM-6L-L-1-G18-0L6H-V1N-S1C1
The Festo 571448 is a pilot-controlled diaphragm regulator featuring a 3-way proportional pressure control valve with electrical actuation and a soft sealing principle. It operates within a pressure regulation range of 0.06 bar to 6 bar (0.006 MPa to 0.6 MPa), an inlet pressure of 0 bar to 8 bar (0 MPa to 0.8 MPa), and delivers a normal nominal flow rate of 900 l/min normalized to DIN 1343. This component includes a backlit LCD, a mechanical spring reset method, short-circuit and reverse polarity protection for all electrical connections, and maintains outlet pressure in an uncontrolled form if the supply cable breaks.

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.
