High Quality for China Manual Butterfly Valves - Concentric double flanged butterfly valve from DN80 to DN1600 – Hongbang Detail:
Concentric double flanged butterfly valve from DN80 to DN1600
The concentric double flanged butterfly valves series OK20 have been designed, generally, for industrial applications where dimensional problems are important.
Their bolting design, on both sides, allows the dismantling of only one part of the installation while maintaining the other one under pressure and operational. They also facilitate the assemblies requiring a temporary isolation of some parts of the network in settlements such as pumping stations, warehouses, naval installations, etc.
Field of use
Different materials and coatings used for butterfly valves and liners can have a large response to many situations in the industrial area of drinking water and other fluids as the raw water, sea water, etc.
It provides an effective and reliable solution in conditions of work as may be pumping stations, water treatment, desalination, irrigation, etc.
