mfh-5/3g-d-3-c-ex
Selling Points
- 1The MFH-5/3G-D-3-C-EX solenoid valve offers a standard nominal flow rate of 4100 l/min, making it suitable for high-demand applications in industrial automation.
- 2This valve is certified to ATEX categories II 2G and II 2D, ensuring safe operation in hazardous environments with gas and dust.
- 3The valve is electrically actuated, providing precise control over its operation via a solenoid coil that must be ordered separately.
- 4Constructed with a die-cast aluminum housing and using HNBR and NBR seals, this valve is designed for durability and resistance to various operating conditions.
- 5The valve operates within a wide temperature range of -5°C to +40°C and can handle operating pressures from 0.3 MPa to 1 MPa (3 bar to 10 bar).
