NBR Wafer Butterfly Valve Supplier and Manufacturer

NBR wafer butterfly valve is a valve with simple structure, small size, light weight and convenient operation, which can be used to adjust and cut off the flow of fluid medium. The characteristic of the manual wafer butterfly valve is that the valve is connected between the two pipe flanges with stud bolts, and no additional gaskets are needed, so the installation is convenient and quick. The switch of the manual wafer butterfly valve is controlled by the handle, and the valve can be fully opened and fully closed by only rotating 90 degrees.

NBR (Nitrile Butadiene Rubber) is a commonly used soft sealing material, which is prepared by emulsion polymerization of butadiene and acrylonitrile. The advantages and characteristics of NBR valve seat material are:

• It has excellent oil resistance and can withstand the erosion of various mineral oils, animal and vegetable oils, lubricating oils and other oil products.
• High wear resistance, can withstand greater pressure and friction, prolong the service life of the valve.
• It has good heat resistance and can work normally in the temperature range of -40°C to 120°C.
• Strong adhesion, can be firmly bonded with metal or other materials to improve sealing performance.

NBR seat material is suitable for the following occasions:

• Oil transportation, processing and storage systems in petroleum, chemical, metallurgical and other industries.
• Hydraulic, pneumatic, fuel and other systems in industries such as automobiles and machinery.
• Animal and vegetable oils, fats and other systems in food, pharmaceutical and other industries.
