Festo MHA1-M1H-2/2G-0,9-PI Air Solenoid Valve (Order Number: 197044)
Product Overview
The Festo MHA1-M1H-2/2G-0,9-PI is a compact, direct-acting 2/2-way normally closed (NC) monostable solenoid valve optimized for vacuum and low-pressure pneumatic applications. Designed for precise on/off control of compressed air or vacuum in automation systems—such as pick-and-place machinery, vacuum holding fixtures, and small fluid handling setups—it features a space-saving 10 mm construction width and direct actuation that eliminates the need for external pilot pressure, simplifying system integration. Its robust poppet valve design with soft sealing ensures reliable operation across a pressure range of -0.9 bar to 2 bar, making it ideal for both vacuum and low-pressure positive air scenarios. The valve is RoHS-compliant and carries UL recognition, meeting global industrial standards for safety and environmental compatibility, while its optional manual override supports quick commissioning and troubleshooting without power.
Main Functions
- 2/2-Way Normally Closed On/Off Control
The valve stays closed by default; energizing the solenoid opens the flow path between the inlet and outlet. De-energizing triggers a mechanical spring to reset the valve to the closed position, enabling fail-safe shutoff in case of power loss.
- Vacuum & Low-Pressure Regulation
It reliably controls both vacuum (down to -0.9 bar) and low positive pressure (up to 2 bar), supporting applications like workpiece vacuum clamping, small component suction, and low-flow air circuit switching.
- Direct Actuation for Rapid Response
Direct solenoid actuation eliminates pilot air dependencies, delivering fast switching times (opening ~4 ms, closing ~5 ms) to enhance cycle efficiency in high-speed automation tasks.
- Manual Override for Maintenance
The non-detenting push-button manual override allows manual valve actuation, facilitating system setup, leak testing, and troubleshooting without electrical power.
- Space-Saving Manifold Mounting
With a 10 mm grid dimension, it integrates seamlessly into compact valve manifolds, reducing installation footprint and simplifying tubing and wiring in dense automation setups.

Structural Highlights
- Poppet Valve Design
The spring-returned poppet valve with soft sealing ensures tight shutoff and low leakage, critical for maintaining vacuum integrity and pressure stability in precision systems.
- Direct Solenoid Actuation
No external pilot air is required, reducing system complexity and enabling reliable operation even in low-pressure or vacuum environments where pilot air may be unavailable.
- Compact Manifold Compatibility
The 10 mm width and grid dimension allow dense manifold mounting, optimizing space in control cabinets and machine-mounted valve stations.
- Non-Detenting Manual Override
The push-button override returns to the default position when released, preventing accidental valve locking during maintenance.
- Durable Materials
The valve body uses high-grade engineering plastics and corrosion-resistant internal components, ensuring long service life even in industrial environments with dust and temperature fluctuations.
