Product Description
Backflow preventers of this type are suitable for the protection of drinking water systems against back pressure, back flow and back syphonage.
The backflow preventer protects drinking water for fluids up to and including liquid category 4 to EN 1717. They can be used for residential buildings, industrial and commercial purposes within the scope of their specification.The powder coated ductile iron housing provides increased corrosion protection.
