Festo
187338
Proportional pressure control valve MPPES-3-1/4-6-420
The Festo 187338 is a pilot-controlled piston control valve featuring a 3-way proportional pressure control valve closed design with a 7 mm nominal width for both pressurization and exhaust. Operating on a nominal DC voltage of 24 V within an 18 V to 30 V range, it utilizes soft sealing, allows any mounting position, and incorporates short-circuit and reverse polarity protection for all electrical connections. It provides an operating pressure of 8 bar, an inlet pressure range of 7 bar to 8 bar, and a pressure regulation range from 0 bar to 6 bar with a maximum pressure hysteresis of 0.05 bar. Safety instructions dictate that if the power supply cable breaks, the outlet pressure will drop to 0 bar. Submit the exact part number, quantity, and application requirements for a quote.

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.
