Covna valves are made from wear-resistant and corrosion-resistant materials, significantly extending their lifespan. In harsh chemical and high-temperature environments, the lifespan of the valves can exceed 15 years, reducing the frequency of replacement and maintenance. For instance, valves made from specialty stainless steel and alloys last more than 50% longer than traditional valves, lowering maintenance costs. ISO 9001 certified, additional certifications include CE, TUV, RoHS, SGS, BV, explosion proof and fire safety
