The valve body is made of high-performance aluminum alloy material, which can effectively prevent the temperature difference of the valve body and achieve no condensation on the surface of actuator and flange.
The valve body material has low water absorption, corrosion resistance, heat insulation and cold insulation, which is 4 times of the common material.
The valve plate is made of 304 material, and its mechanical properties and anti-corrosion properties are up to standard.
The rubber of valve seat uses EPDM rubber that meets the standard, which makes the resilience and pulling force of butterfly valve super stable and reliable, and there is no leakage even if it opend or closed more than 10000 times.
PE heat shrinkable plastic packaging technology are used in product packaging. Each Bundor product is individually packed with heat shrinkable film and built-in desiccant, which isolates air dust and helps to store and avoid product corrosion caused by moisture.
