The transformer radiator butterfly valve CI is a cast‑iron butterfly valve engineered for oil‑filled transformer and power transformer radiator systems. It features a cast iron body of Grade 200/250 (also known as GG25 or GJL‑250), an epoxy‑coated finish, and flange connections. The valve is offered in nominal diameters ranging from DN50 to DN200 and conforms to a PN16 pressure class suitable for utility and industrial distribution networks. Its design enables quick operation and reliable flow control in high‑load electrical infrastructure.
The valve body is produced from cast iron that provides high strength and resistance to the elevated temperatures typical of transformer environments. Epoxy coating is applied to protect against corrosion caused by transformer oil. In the broader valve market, similar radiator butterfly valves often use the same material grades and coating systems, making this product consistent with standard industry practice. Typical operating temperature limits for such cast‑iron valves lie between - 40 °C and 150 °C, allowing use across most climate zones.
Primary users include transformer manufacturers, power plant maintenance teams, and utility service providers that require dependable oil flow regulation. The supplier indicates flexible minimum order quantities and packages the units for safe transit, with shipping terms that may include FOB or CIF. Payment methods commonly accepted are L/C and T/T, but buyers should confirm the exact terms with the supplier before finalising any contract.

Before placing an order, verify that the cast‑iron grade, coating thickness and flange standard match the technical specifications of your transformer cooling system. Ask the supplier for material test certificates, coating inspection reports and a drawing that shows the flange dimensions. Confirm that the valve has been tested according to IEC 60534 or an equivalent standard, especially if the installation operates near the upper temperature limit.
Logistics should be clarified early; typical lead times, shipping incoterms and freight options vary with order size. Request confirmation of whether the supplier offers FOB at a Chinese port or CIF to your destination, and agree on the exact Incoterm (e.g., FOB Shanghai, CIF Hamburg). Payment terms such as L/C at sight or T/T should be documented in the sales contract before any advance payment is made.
Quality assurance for imported valves includes third‑party inspection, pressure testing and verification of the epoxy coating integrity. Ask the supplier to arrange a pre‑shipment inspection by a recognised inspection house and to provide the inspection report, test certificates and any applicable conformity documentation. Maintaining these records will simplify customs clearance and ensure the valve performs reliably in service.
