Key Features
1
Precise Control and Flow ManagementThe MFH-5/3G-D-1-S-C-EX offers precise control over pneumatic flow rates, ensuring optimal performance in various industrial applications. Its standard nominal flow rate is 1200 l/min, making it suitable for demanding tasks.
2
Reliable Mechanical Spring ResetEquipped with a mechanical spring reset mechanism, this valve ensures consistent and reliable operation. The mechanical spring provides a secure return to the closed position, minimizing the risk of valve failure.
3
Soft Sealing for LongevityThe soft sealing principle used in the MFH-5/3G-D-1-S-C-EX ensures long-lasting performance and minimizes wear and tear. This feature is particularly beneficial in applications where the valve is subject to frequent operation.
4
High-Performance Electrical ActuationThe valve is electrically actuated, allowing for fast and efficient operation. The switching times are optimized with an off time of 35 ms and an on time of 18 ms, ensuring rapid response to control signals.
