Overview
The Festo CPE24-M1H-5/3G-3/8 (part number 170265) is an industrial-grade solenoid directional control valve engineered for pneumatic automation systems. This 24 mm wide, 5/3-way valve with mid-position closed function provides responsive electrical actuation and is manufactured to ISO/IEC standards with C UL US recognition. The valve’s compact form factor and high flow rating make it ideal for OEM equipment builders, system integrators, and maintenance operations requiring reliable directional control.
Key Features
- 5/3-way, mid-position closed function — ensures safe, controlled air routing with spring-centered neutral position
- 24 mm modular width — compatible with Festo CPE manifold systems for high-density valve stacking
- G3/8 pneumatic ports — standard metric porting for industrial pneumatic applications
- Electrical actuation (ZC plug pattern) — 24 VDC solenoid coil with integrated coil socket for quick field replacement
- 3000 l/min nominal flow rate — operates reliably across 2.5–10 bar pressure range
- IP65 protection rating — sealed connector and pilot air design for shop-floor durability

Replaces / Drop-In Replacement For
The CPE24-M1H-5/3G-3/8 is a direct equivalent replacement for Festo part number 170265 and systems originally designed around this valve model. It shares the same electrical connector (ZC), port configuration (G3/8), and pneumatic performance characteristics. For equivalent models from other manufacturers (e.g., Bosch Rexroth 4WRPEH, Eaton VBSO, Parker D1FP), verify connector voltage, solenoid coil power rating, and port thread size with your system integrator before substitution.
Works With
- Festo pneumatic components: DHPS cylinders, ADVUL rod seal kits, MSV silencers, tubing & fittings
- Manifold integration: Festo CPE cavity plates, cavity subplates, sandwich modules (24 mm width)
- Electrical control: 24 VDC solenoid coils, relay modules, PROFIBUS/PROFINET networked valve terminals
- Flow control: Festo SRP proportional pressure regulators, flow control valves for meter-in/meter-out
