The UV drain valves and breathers are normally used in the chemical and petrochemical plants, off-shore platforms, refineries and any other industry where hazardous atmospheres (gas and combustible dust) are potentially present.
The drain valves and breathers are specially recommended for tropical environment where the phenomenon of water condensation mixed with chemical agents is the first cause of corrosion of electrical components inside the enclosures.
The material used to manufacture drain valves and breathers UV series have been studied to allow the maximum protection against the highly corrosive agents present in these industries:
- bushing and shaft, as components directly involved into the explosion proof protection, are made of
stainless steel AISI 316 - internal o-ring of silicone
- external gasket of silicone
- adaptor for thin wall enclosures (≤ 8 mm.) and locknut of stainless steel AISI 316
