Why do DI and EPDM wafer butterfly valves have high cost performance

In the Jinbin workshop, two wafer butterfly valves customized by the customer are undergoing final inspection. The size of the wafer butterfly valve is DN800, with the valve body made of ductile iron and the valve plate made of EPDM, meeting the customer’s working conditions. DCIM100MEDIADJI_0670.JPG

The core advantages of EPDM wafer butterfly valves are prominent, combining performance and economy

EPDM valve plates feature outstanding elastic recovery and weather resistance, with a wide temperature range of -40℃ to 120℃. They have a high tolerance to weak corrosive media such as acids, alkalis, and sewage, achieving zero-leakage sealing. The DN800 large diameter design, combined with the low flow resistance feature of the wafer type butterfly valve, has a strong flow capacity, meeting the transportation requirements of large flow media and reducing the energy consumption of the pipeline network. DCIM100MEDIADJI_0670.JPG

The wafer style butterfly valve structure reduces the weight by 30% compared with the flanged butterfly valve, does not require large hoisting equipment, is easy to install and disassemble the valve plate, and has low maintenance costs in the later stage. EPDM material is resistant to aging and tearing. When paired with stainless steel valve stems, it is less prone to wear in media containing sand and suspended solids. Its service life is 2 to 3 times longer than that of ordinary rubber valve plates. Moreover, in large-diameter scenarios, its manufacturing cost is over 40% lower than that of ball valves and gate valves, and the installation and operation and maintenance costs are also reduced. It combines high performance with high cost performance. DCIM100MEDIADJI_0670.JPG

Its practical applications cover key scenarios in multiple industries:

In municipal water supply and drainage projects, it is suitable for the main pipes of urban water supply networks, the inlet and outlet pipes of sewage treatment plants, and the sewage discharge systems of sedimentation tanks. It can withstand the erosion of organic matter and sediment in sewage and is sealed to prevent leakage. In the field of water treatment, EPDM can be used for backwashing pipelines of filter tanks in waterworks and reclaimed water reuse systems. Epdm is non-toxic and environmentally friendly, and meets the hygiene standards for drinking water. DCIM100MEDIADJI_0670.JPG

It is suitable for the pipelines transporting acid and alkali solutions and chemical waste liquids in the chemical industry, and can withstand the corrosion of organic acids, alkali salts and other media. In HVAC and centralized heating scenarios, it is suitable for urban centralized heating networks and water circulation systems in large industrial parks. It has low flow resistance and suitable temperature resistance, improving heat exchange efficiency. In the power and metallurgical industries, it can be used in the circulating water pipelines of power plants and the cooling water systems of steel mills, and can withstand the erosion of high-temperature circulating water and industrial impurities. In the fields of agriculture and water conservancy, it is suitable for the main water conveyance pipes of large irrigation districts and the flood discharge pipes of reservoirs. It is resistant to ultraviolet aging, adaptable to harsh outdoor environments, and meets the demand for high-flow water conveyance. DCIM100MEDIADJI_0670.JPG
