Zhengyuan Valve Group Co., Ltd., based in Wenzhou’s Longwan District, is expanding its valve solutions to serve the growing concentrated solar power (CSP) sector . CSP plants, which utilize molten salt thermal storage systems, require valves capable of withstanding high temperatures up to 600°C and corrosive molten salt environments over long service periods . Zhengyuan offers a comprehensive material selection strategy for CSP applications: high-temperature alloy steel valves (WC6, WC9 grades) for molten salt piping and heat exchangers, and duplex stainless steel valves for chloride-containing salt storage conditions . The company’s valve products feature hardfaced sealing surfaces using cemented carbide materials to enhance wear and corrosion resistance in high-temperature media . With pressure ratings from 0.1MPa to 42MPa and temperature capabilities from -196°C to 730°C, Zhengyuan supports diverse CSP system requirements . Through rigorous material selection and manufacturing quality control, Zhengyuan Valve Group maintains its focus on delivering reliable valve solutions for emerging clean energy infrastructure.
