Product Model
mfh-5/3g-1/8-b-ex
Selling Points
- 1The MFH-5/3G-1/8-B-EX solenoid valve offers a standard nominal flow rate of 1000 l/min, making it suitable for high-pressure applications with operating pressures ranging from 0.3 MPa to 1 MPa.
- 2This valve is certified to ATEX categories II 2G and II 2D, ensuring safe operation in potentially explosive environments. It also meets UK EX instructions for Zone 1 and Zone 21.
- 3The valve features a piston gate design with a mechanical spring return, providing reliable operation and long service life. It is constructed with a soft sealing principle and has a grid dimension of 27 mm.
- 4The MFH-5/3G-1/8-B-EX offers optional manual override and non-detenting manual override, allowing for flexible mounting positions. It can be piloted with internal or external pilot air supply.
- 5The valve includes safety features such as a maximum switching frequency of 3 Hz, a maximum positive test pulse of 2200 μs, and a maximum negative test pulse of 3700 μs. It also meets IP65 protection standards and has a product weight of 440 g.
