Festo
543433
Proportional pressure control valve VPPM-8
The Festo 543433 is a pilot-controlled diaphragm regulator featuring a 3-way proportional pressure control valve with a nominal pressurization width of 8 mm and a soft sealing principle. It operates across a pressure regulation range of 0.02 bar to 10 bar, an inlet pressure of 0 bar to 11 bar, and delivers a normal nominal flow rate from 450 l/min to 2750 l/min normalized to DIN 1343. Powered by a DC operating voltage range of 21.6 V to 26.4 V, this electrical-actuated component includes a backlit LCD and LED display, short-circuit and reverse polarity protection for all electrical connections, a mechanical spring reset method, and a 100% duty cycle with a maximum electrical power consumption of 7 W.

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.
