Technical Overview

The Festo MFH-5-1/8-B is a 5/2-way monostable solenoid valve designed for high-performance industrial automation. Utilizing a durable poppet seat design and electric actuation, it provides a standard nominal flow rate of 750 l/min. The valve features a mechanical spring reset, internal pilot air supply, and a non-detenting manual override. Housed in die-cast aluminium with NBR and TPE-U(PU) seals, it is engineered for reliable operation within a pressure range of 2 to 10 bar.

Industrial Applications

1. Automated Packaging Machinery Carton Folding

Utilizing the Festo MFH-5-1/8-B to control double-acting pneumatic cylinders in a high-speed carton erecting machine. The 5/2-way monostable function ensures the cylinder extends to fold flaps when electrically actuated and reliably retracts via mechanical spring reset.

Problem Solved

Prevents machine jams during power faults by ensuring fail-safe automated retraction via monostable spring reset, while delivering a quick 10 ms switching time on and 750 l/min nominal flow for rapid and synchronized cylinder extension.

2. Conveyor Diverting and Sorting Systems

Operating pneumatic diverter gates in a logistics sorting center. The electrically pilot-actuated poppet valve drives a double-acting cylinder to accurately push varying package sizes into designated chutes across the distribution line.

Problem Solved

Resolves the need for robust and consistent directional control of air flow at a maximum switching frequency of 3 Hz. The durable poppet seat design and soft sealing handle the repetitive actuation without rapid wear, operating smoothly between 2 bar and 10 bar.

3. Automated Workpiece Clamping Fixtures

Integrating the MFH-5-1/8-B valve to actuate pneumatic clamping cylinders in an automated assembly or machining station. The valve regulates air flow to the clamp, securing the part in place before processing begins.

Problem Solved

Maintains reliable clamping force using the 0.2 MPa to 1 MPa operating pressure range. The die-cast aluminium housing provides necessary durability in industrial environments, and the G1/8 ports allow sufficient air delivery for swift 30 ms switching time off clamping release.
