Application Scope

The Festo MFH-3-1/4-S-NPT 10873 is a 3/2-way air solenoid valve built for pneumatic automation systems. It suits engineers and technicians who need electrically actuated, pilot-controlled directional control with a standard nominal flow rate of 800 l/min and a nominal width of 7 mm.

Sustained Operation

The valve operates across a pressure range of -0.95 bar to 10 bar and handles ambient temperatures from -5 °C to 40 °C with a medium temperature span of -10 °C to 60 °C. Its IP65 rating and CRC 1 corrosion resistance support continuous duty in protected industrial environments, while the mechanical spring reset ensures reliable return positioning over extended cycles.

Installation Requirements

Verify that your control system can supply a pilot pressure between 1 bar and 8 bar through an external pilot air port and that compressed air meets ISO 8573-1:2010 [7:4:4] quality. The unit requires a separately ordered solenoid coil for the operating voltage and connects via 1/4 NPT pneumatic working ports with a reversible flow direction option.

Questions about this item

Does the 10873 valve generate much heat or noise when energised continuously?

The coil is ordered separately, so heat and sound depend on the coil chosen; the valve body itself has no moving fan and is rated IP65 for ambient temperatures up to 40 °C.

What separate components must I already have to operate this 1/4 NPT valve?

You need a compatible solenoid coil for the required voltage, a compressed-air supply filtered to ISO 8573-1:2010 class 7:4:4, and pilot air at 1 to 8 bar.

Will the 30.5 mm wide MFH valve fit on a legacy manifold that uses 1/4 NPT ports?

Yes — the working port is 1/4 NPT, the nominal width is 7 mm, and the flow direction is reversible, so it connects directly to existing 1/4 NPT plumbing.
