Festo
1691730
Proportional pressure control valve VPPL-3Q-3-0L40H-A4-A-S1-3
The Festo 1691730 is a directly controlled piston regulator featuring an electrical actuation type, a soft sealing principle, and a 3 mm nominal width for both pressurization and exhaust. Operating with an inlet pressure range of 0 bar to 50 bar and a pressure regulation range of 0.4 bar to 40 bar, this 3-way proportional pressure control valve closed includes an LED indicator display, mechanical spring reset, and reverse polarity protection for all electrical connections. It maintains a maximum pressure hysteresis of 0.4 bar, supports a maximum cable length of 30 m, and incorporates a safety position that drops the outlet pressure to 0 bar if the power 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.
