High Corrosion ResistanceConstructed from die-cast aluminum with NBR seals, this valve offers moderate corrosion resistance (CRC 2), ensuring it can withstand the rigors of industrial environments while maintaining its performance over time.

Non-Reversible Flow DirectionThe valve operates with a non-reversible flow direction, ensuring that the compressed air or inert gases flow consistently from right to left, which is crucial for maintaining system integrity and efficiency.

Standard Nominal Flow RateWith a standard nominal flow rate of 2,000 liters per minute, this valve is capable of handling substantial air or gas flow rates, making it suitable for a wide range of industrial applications.

Operating Pressure RangeThe MS4N-DL-1/4 operates within a pressure range of 4 to 14 bar, providing flexibility in system design and operation. This range ensures that the valve can handle various pressure requirements, from low to high-pressure applications.

Mechanical Spring ResetFeaturing a mechanical spring reset, this valve ensures reliable operation and quick recovery from any pressure fluctuations, maintaining system stability and efficiency.

Compliance with Industry StandardsThe Festo MS4N-DL-1/4 soft start valve is designed to comply with industry standards, including ISO 8573-1:2010 for compressed air quality and VDMA24364-B1/B2-L for pneumatic components, ensuring it meets the highest standards of quality and performance.
