Festo 163166 is a CPE24-M1H-5L-3/8 solenoid valve designed for pneumatic automation applications requiring dependable directional control of compressed air. This 5/2-way monostable valve is electrically actuated with a 24 V DC coil and uses a pilot-operated piston gate valve design with pneumatic spring reset. With a 24 mm construction width, G3/8 pneumatic ports and a nominal flow rate of 2900 l/min, it is suited to controlling double-acting pneumatic actuators in industrial machinery and process equipment.

The valve operates across a pressure range of 2.5 to 10 bar and is suitable for compressed air to ISO 8573-1:2010 [7:4:4]. It features internal pilot air supply, non-reversible flow direction, soft sealing and optional mounting orientation, giving it flexibility for integration into compact pneumatic systems. The IP65 protection rating with plug socket supports use in demanding industrial environments, while the die-cast aluminium housing and NBR seals provide robust mechanical construction.

Additional features include manual override capability, exhaust-air flow control option, Type C electrical connection, G3/8 ports for connections 1 to 5, M5 pilot air and pilot exhaust ports, and a 100% duty cycle. With switching times of 40 ms on and 50 ms off, the Festo 163166 offers fast, reliable pneumatic switching performance for automated production equipment, handling systems and machine control assemblies.

What type of component is this?

This is a 5/2-way monostable solenoid valve designed for pneumatic automation systems. It is electrically actuated and pilot operated, with a pneumatic spring return.

What voltage does the valve use?

The valve operates on 24 V DC. Its coil data is rated at 1.5 W, with permissible voltage fluctuations of -15% to +10%.

What pneumatic port size does it have?

The main pneumatic ports are G3/8, including ports 1, 2, 3, 4 and 5. The pilot air and pilot exhaust ports are M5.

What is the operating pressure range?

The operating pressure range is 0.25 MPa to 1 MPa, equivalent to 2.5 bar to 10 bar.

What is the standard nominal flow rate?

The standard nominal flow rate is 2900 l/min, standardised according to DIN 1343.

Can it be mounted in different positions?

Yes. The mounting position is optional, and the valve is designed for mounting with through-holes.

What level of ingress protection does it provide?

The valve has an IP65 degree of protection when used with a plug socket, in accordance with IEC 60529.

What temperature range is it designed for?

The media and ambient temperature ranges are both -5 °C to 50 °C.

What materials are used in its construction?

The housing is made from die-cast aluminium, and the seals are made from NBR. The part is also RoHS-compliant.

What is the switching performance of the valve?

For 163166, the switching time is 40 ms when switching on and 50 ms when switching off. The duty cycle is rated at 100%.

What operating medium is suitable for this valve?

It is intended for compressed air to ISO 8573-1:2010 [7:4:4]. Lubricated operation is possible, but once used with lubrication, continued lubricated operation is required.

Does it include manual override functionality?

Yes. The valve includes a non-detenting manual override, with detenting possible via an accessory.
