3/2 Way Single Namur Ex-Proof Directional Valve

Cematic's stainless steel 3/2 NAMUR Ex-Proof directional valve is the perfect choice for pneumatic systems in explosive atmospheres. Thanks to its II 2G Ex mb IIC T4 Gb certification, it ensures safe and reliable flow control. Therefore, it is the ideal solution where intrinsic safety is an essential requirement.

In addition, its stainless steel body offers superior corrosion resistance compared to the aluminum model, making it especially suitable for environments with aggressive chemical agents.

Since it complies with standard NAMUR dimensions, it facilitates direct mounting on compatible actuators without intermediate accessories. Consequently, it is a robust and low-maintenance option for plants with demanding operating conditions. Likewise, its 24VDC operation adapts it to low-voltage control panels without additional modifications.
