Festo MN1H-5/2-D-2-FR-C Air Solenoid Valve (Order Number: 159699)

Product Overview

The Festo MN1H-5/2-D-2-FR-C is a heavy-duty, 5/2-way double-solenoid bistable pneumatic valve, engineered for high-flow and high-pressure industrial automation applications. As a core component of Festo’s MN1H series, it is designed to control the direction of compressed air in large-scale pneumatic systems, such as heavy-duty cylinder actuation, material handling equipment, packaging lines, and automotive assembly machinery. With its robust die-cast aluminum housing, high nominal flow rate, and bistable operation (maintains position without continuous power), this valve delivers reliable performance in harsh industrial environments while minimizing energy consumption. It features a push-in locking (FR) pneumatic connection design for fast tubing installation, and its compliance with international standards ensures seamless integration into both standalone and centralized valve systems.

Main Functions

5/2-Way Bistable Directional Control

As a 5/2-way valve, it manages air flow between one inlet port (1), two working ports (2, 4), and two exhaust ports (3, 5). The bistable double-solenoid design allows the valve to switch and lock into either of two positions without continuous power supply—energizing solenoid A shifts the valve to connect port 1 to port 2 and vent port 4 to port 5; energizing solenoid B shifts it to connect port 1 to port 4 and vent port 2 to port 3. This ensures energy efficiency and fail-safe position retention during power outages.
High-Flow Air Delivery

Optimized internal flow channels enable a large nominal flow rate, supporting rapid actuation of large-bore cylinders and high-volume pneumatic devices, which shortens machine cycle times and boosts operational efficiency.
Tool-Free Push-In Pneumatic Connection

The FR-type push-in locking connections allow quick, tool-free assembly of pneumatic tubing, reducing installation time and eliminating the risk of thread damage associated with traditional threaded connections.
Manual Override for Maintenance

Equipped with lockable manual override buttons on both solenoid sides, the valve can be manually actuated for system commissioning, leak testing, or emergency operation when electrical power is unavailable. The lockable design prevents accidental position shifts during maintenance.
Wide Pressure Range Adaptability

It operates across a broad pressure spectrum, making it suitable for both low-pressure control tasks and high-pressure heavy-load applications, with strong compatibility for different industrial pneumatic systems.

Structural Highlights

Bistable Springless Design

The valve uses a mechanical locking mechanism instead of springs to maintain position, reducing internal wear and extending service life, while also cutting down on energy consumption by eliminating the need for continuous solenoid power.
Robust Die-Cast Aluminum Housing

The painted die-cast aluminum housing provides excellent mechanical strength, corrosion resistance, and impact resistance, making the valve suitable for dusty, humid, and vibration-intensive industrial environments.
Optimized Internal Flow Path

The streamlined internal valve core and flow channels minimize pressure loss, ensuring maximum air flow efficiency and rapid response for large pneumatic actuators.
Push-In Locking Connections

The FR-C push-in ports enable secure, tool-free tubing installation and removal, with a locking mechanism that prevents accidental disconnection even under high vibration.
Isolated Solenoid Compartments

Solenoids are housed in sealed, isolated compartments to protect internal electrical components from dust and moisture, ensuring stable operation and complying with the IP65 protection class standard.
