Name: Festo 164331 Proportional pressure control valve MPPE-3-1/4- -B
Brand: Festo

Proportional pressure control valve MPPE-3-1/4- -B

The Festo 164331 is a pilot-controlled piston control valve featuring a nominal width of 7 mm for both pressurization and exhaust, operating across an input pressure range of 11 bar to 12 bar and a regulation range of 0 bar to 10 bar. This electrically actuated component with soft sealing operates on a DC voltage range of 18 V to 30 V, supports 0–10 V voltage or 4–20 mA current setpoint and actual values, and utilizes compressed air per ISO 8573-1:2010 [7:4:4] or inert gas. It carries an RCM compliance mark and CE marking per the EU EMC directive, maintaining uncontrolled outlet pressure upon supply cable breakage.

Why 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.

Engineering context

Identification and RFQ Guidance

Confirm the exact configuration

Use the manufacturer part number and model code—not appearance alone. Connection, size, material, voltage, pressure, seal, and control options can differ within the same product family.

What to include in your RFQ

Provide quantity, delivery country and ZIP/postal code, required condition, target date, and photographs of the existing nameplate when available.
