Dongying Lake Petroleum Technology Company in China manufactures a D371f-16c butterfly valve that uses a rotating disc to regulate flow in pipelines. The valve code is listed as D and it incorporates a handle‑drive, two‑screw link transmission, three‑worm transmission, as well as pneumatic and electric actuation options. The disc can be positioned precisely thanks to an integrated worm gear reducer that provides self‑locking capability. The design allows the valve to reach a fully open position with a disc angle of less than 90°.
The sealing suite includes X‑NBR, XE‑EPDM, XSI silicone rubber, XT fluorine rubber, XT special rubber and PTFE, giving resistance to a range of chemicals commonly encountered in petrochemical services. Body construction options cover HT200 cast iron, carbon steel and Q‑iron, materials that balance strength and cost for medium‑pressure applications. In the broader industry, butterfly valves of this size typically use cast iron or carbon steel bodies and employ similar elastomer seals for leak‑tight performance.
These valves are suited to throttling and on‑off control in oil‑field pipelines, water treatment plants and process industries where compact size and quick operation are required. Buyers such as plant engineers, procurement agents and system integrators often request custom disc positioning or gear‑reduced stems for precise flow control. Pricing, minimum order quantities and lead times are not disclosed in the listing, so interested parties should contact the supplier directly to negotiate trade terms.

Before placing an order, verify the valve’s material certifications, pressure test reports and dimensional drawings. Request a mill test report for the selected body material and a seal compatibility chart for the intended fluid. Confirm that the supplier can provide a third‑party inspection certificate if required by your quality system.
Discuss logistics early; ask the supplier which Incoterms they support, such as FOB Shanghai or CIF Ningbo, and obtain an estimated lead time for production and shipment. Payment terms are not stated, so negotiate a suitable schedule, for example a 30% advance with the balance against documentary credit. Ensure that freight forwarders are aware of the valve’s weight and packaging dimensions to avoid unexpected charges.
Plan for on‑site inspection or factory‑audit if possible, focusing on valve seat alignment, disc positioning accuracy and seal integrity. Request a functional test report (e.g., pressure‑tightness and torque verification) before loading. Obtain all relevant documentation, including a declaration of conformity, material test certificates and a warranty statement, to streamline customs clearance and warranty claims.
