Festo
187328
Proportional pressure control valve MPPES-3-1/2-2-010
The Festo 187328 is a pilot-controlled piston control valve featuring a 3-way proportional pressure control valve closed function with an 11 mm nominal width pressurization and a 12 mm exhaust nominal width. This electrical component utilizes a soft sealing principle, operates on a nominal DC voltage of 24 V within a range of 18 V to 30 V, and provides a pressure regulation range of 0 bar to 2 bar at an operating pressure of 4 bar. Integrated short-circuit protection and reverse polarity protection apply to all electrical connections, while the built-in safety mechanism ensures the outlet pressure drops 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.
