The CompoSeal valve from Tyco Valves comprises a range of highly engineered butterfly valves made from a blend of two thermoplastics that offer increased design flexibility, while remaining firmly within existing regulatory framework and industrial design standards such as ISO, EN, API, PED and EnEv. CompoSeal offers multiple environmental advantages over traditional valve construction, according to the manufacturer. It requires less energy in production than traditional metals through the use of injection molding technology as opposed to foundry production and uses reduced amounts of raw materials when compared with traditional methods. The composite materials may also be reused many times over as the valves are fully recyclable, providing a key advantage given the increasing importance of sustainability. The combination of these elements can reduce CO2
emissions by up to 70 percent based on 10,000 valves when compared to traditional ductile iron products, according to the manufacturer.
