Import Api Oilfield Drilling Wellhead Choke Valve — Buy in wholesale FOB from Supplier in China

The API oilfield drilling wellhead choke valve is a critical component of Christmas tree assemblies, designed to regulate production rates from oil wells with working pressures up to 20,000 psi. This valve is available in two configurations: adjustable and positive. The adjustable type uses a hand wheel to rotate the stem, modifying the flow area for precise rate control, while the positive type achieves regulation by changing flow beans. Both variants are engineered for high-pressure environments, with nominal dimensions ranging from 2-1/16 to 7-1/16 inches.

Materials and construction prioritize durability in harsh conditions. The adjustable choke valve features a tungsten carbide needle and spool for corrosion and abrasion resistance, with pintle and sleeve types suited for wellheads, Christmas trees, and choke manifolds. The positive choke valve uses ceramic or tungsten carbide choke beans, also resistant to wear and corrosion, and incorporates a union bonnet for rapid bean replacement. An indicator lens with scale marks provides real-time feedback on stem position and orifice area, enabling operators to monitor flow adjustments accurately.

These choke valves are deployed in onshore and offshore drilling operations where precise control of crude oil or natural gas flow is essential. Buyers typically include exploration and production companies, drilling contractors, and service providers requiring reliable pressure regulation. The valves operate across a temperature range aligned with PSL1 to PSL4 and PR1 to PR2 performance requirements, with material classes from AA to FF. Confirm compatibility with your wellhead system and working medium before procurement, as specifications such as working temperature and exact pressure ratings must align with operational demands.

Dongying Lake Petroleum Technology Co., Ltd is based in Dongying, Shandong Province, China, with its address on Huanghe Road. The company specializes in oilfield equipment, including wellhead components like choke valves, and operates as an imported-tier supplier. Its profile indicates a focus on manufacturing products compliant with API standards, catering to the technical demands of oil and gas extraction.

The supplier’s trust tier is classified as harbor, and while its response rate is currently listed as 0.00, this reflects a lack of recorded interactions rather than a statement on capability. The company’s product descriptions emphasize engineering precision, such as the use of tungsten carbide and ceramic materials for wear resistance, and functional designs like union bonnets for rapid maintenance.
