Technical Overview

The Festo CPE24-M1H-3GL-3/8 (Part Number: 163165) is a high-performance 3/2-way, normally closed, monostable pneumatic solenoid valve designed for rigorous industrial automation applications. Operating at a control voltage of 24V DC, this valve utilizes a precise piston spool design with a soft sealing principle and pneumatic spring reset. Engineered to minimize spatial footprint, it features a compact 24mm width while delivering an impressive standard nominal flow rate of 2500 l/min. This makes it an ideal solution for systems demanding high volumetric flow in confined installation areas. The robust housing is constructed from die-cast aluminum and is rated IP65, providing substantial protection against dust and low-pressure water ingress. Designed to handle operating pressures ranging from 2.5 to 10 bar (0.25 to 1 MPa), it features standardized G3/8 threaded pneumatic connections for rapid integration. With internal pilot air supply and fast cycle responsiveness, it enables rapid, highly efficient pneumatic switching for sophisticated machinery and fluid control setups.

Industrial Applications

1. High-Speed Actuation for Packaging Automation

The Festo CPE24-M1H-3GL-3/8 is utilized to control the rapid extension and retraction of high-bore pneumatic cylinders in end-of-line packaging systems. The 2500 l/min flow rate easily fills large actuator volumes quickly, ensuring machine cycle times remain as short as possible.

Problem Solved

Overcomes the slow cylinder response times characteristic of standard valves by providing a high-flow, low-latency pneumatic burst within a restricted 24mm mounting space.

2. Compressed Air Blow-Off Systems in CNC Machining

Integrated into CNC routing and milling stations, this 3/2-way normally closed valve controls high-pressure air nozzles. Triggered by a 24V DC PLC signal, it releases up to 10 bar of compressed air to efficiently eject metal shavings and cooling fluid from the machining area.

Problem Solved

Replaces inadequate low-flow automatic blow-offs by delivering intense, immediate air streams while maintaining operational reliability despite fluid exposure thanks to its IP65 housing.

3. Pneumatic Zone Safety Exhaust

Installed as a zone-isolation and dump valve on an automated assembly line, the monostable normally-closed valve provides a fail-safe mechanism. Upon an emergency stop or 24V DC power loss, the pneumatic spring automatically resets the spool, sealing the incoming G3/8 supply and exhausting downstream air.

Problem Solved

Ensures worker safety by rapidly exhausting trapped pneumatic pressure in a machine zone when power is disconnected, preventing accidental mechanical movement.
