Import Adjustable Orifice Valve — Buy in Bulk from Supplier in South Korea (Republic Of Korea)

The Adjustable Orifice Valve from Donghae Co., Ltd. is a flow control device designed for precision management of bulk materials in industrial applications. It is engineered for use in thermal power plants and cement manufacturing, where it regulates the flow of dust coal, wood chips and cement with adjustable accuracy. The valve’s robust cast iron or carbon steel body (material grade not specified in the listing) ensures resistance to abrasion and high-pressure conditions typical in these environments.

The adjustable orifice mechanism allows operators to fine-tune flow rates by modifying the opening size, which is critical for maintaining consistent material feed in processes like pulverised coal combustion or cement clinker production. Standard industry designs for such valves include a manual handwheel or actuator for adjustment, with typical pressure ratings ranging from PN10 to PN16 bar. The valve’s internal components are often coated with wear-resistant materials like tungsten carbide to extend service life in abrasive applications.

Industries such as energy, construction and heavy manufacturing deploy these valves to optimise process efficiency and reduce operational downtime. Buyers should confirm the valve’s material specification, pressure rating and compatible particle sizes with the supplier, as these directly impact performance in specific applications. The valve is supplied as a standalone unit, with flanged connections typical for easy integration into existing piping systems.

Donghae Co., Ltd. is headquartered in Dalseong-Gun, Daegu, South Korea, with its address at 894 Bongchon-Ri, Habin-Myeon. The company is classified as an imported-tier supplier, indicating a focus on providing industrial components to international markets. It specialises in valves and flow control equipment for heavy industries, including thermal power and cement production.

The supplier’s profile does not list a response rate or average response time, which may indicate limited online activity or a preference for direct contact methods. No certifications or trade references are provided in the listing, so buyers are advised to request these directly to assess compliance with industry standards. Donghae’s product range appears tailored to niche industrial applications rather than general-purpose solutions.
