Name: Festo 187335 Proportional pressure control valve MPPES-3-1/4-2-010
Brand: Festo

Proportional pressure control valve MPPES-3-1/4-2-010

The Festo 187335 is a pilot-controlled piston control valve featuring a 3-way proportional pressure control valve closed design with 7 mm nominal widths for both pressurization and exhaust. Operating on a DC nominal voltage of 24 V within a voltage range of 18 V to 30 V, this electrical component includes short-circuit and reverse polarity protection for all electrical connections alongside soft sealing. It functions across an inlet pressure of 3 bar to 4 bar (0.3 MPa to 0.4 MPa) to provide a pressure regulation range of 0 bar to 2 bar (0 MPa to 0.2 MPa) at an operating pressure of 4 bar (0.4 MPa). Built with any mounting position, it features safety instructions ensuring the outlet pressure drops to 0 bar if the power supply cable breaks, a maximum pressure hysteresis of 0.05 bar (0.005 MPa), an on switching time of 200 ms, and an off switching time of 890 ms.

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.
