Az ISG UNIBALL® floating isolated ball valve is an ISG UNIBALL® floating ball valve with extended operating system. The extended operating element allows the ball valve to have equivalent insulation with the pipeline. Firstly it is used in central heating system. But it can be used everywhere to keep the working temperature of flow. End connection possibilities, size and pressure range, technical parameters (except heights) are the same as ISG UNIBALL floating ball valve (7.10/7.11 and 7.12/7.13).
The stems are sealed with 2 "O„-rings. The material quality of "O„-rings varies depending on the medium:
• EPDM: water, sewage, water-based chemicals, synthetic detergents (Tmax: 130°C)
• Viton: oil, gasoline, natural gas, PB gas, normal and high temperature oils, greases
• AFLAS (TFE/P): due to its higher thermal resistance, mainly raised high water, water vapor (Tmax: 200°C)
