Festo
187331
Proportional pressure control valve MPPES-3-1/2-6-420
The Festo 187331 is a pilot-controlled piston control valve featuring a 3-way proportional pressure control valve closed design with soft sealing and an electrical actuation type. This component provides a pressure regulation range of 0 bar to 6 bar at an inlet pressure of 7 bar to 8 bar, operating on a nominal DC voltage of 24 V within a voltage range of 18 V to 30 V. Integrated short-circuit and reverse polarity protection apply to all electrical connections, and the unit includes a safety function where a power supply cable break causes outlet pressure to drop to 0 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.
