The Adjustable Choke Valve from Yulin International Corporation is engineered for oil and gas wellhead applications, designed to regulate flow pressure and ensure safe, efficient production. It is a critical component in managing fluid and gas output, preventing issues like sand production and pressure surges that can damage upstream equipment. The valve’s adjustable design allows operators to modify the choke size dynamically to adapt to changing field conditions.
This valve is typically manufactured from high-grade alloy steels or stainless steels to withstand extreme temperatures, pressures, and corrosive environments. Standard materials for such valves include ASTM A217 WC6 or A351 CF8M, with trim materials selected for abrasion and erosion resistance. The valve’s internal components, such as the choke bean and seat, are precision-machined to ensure accurate flow control and long service life.
Primary users include oil and gas exploration companies, drilling contractors, and service providers operating in upstream production. The valve is compatible with wellhead assemblies, Christmas trees, choke manifolds, and other critical systems. Bulk orders are common, with buyers specifying pressure ratings, material grades, and connection types to match their operational requirements. Logistics typically involve specialized packaging to prevent damage during transit.

Before placing an order, confirm the valve’s compatibility with your wellhead system, including pressure rating, temperature range, and connection type. Request detailed technical drawings and material certifications to ensure the valve meets your operational specifications. Verify whether the supplier can provide third-party inspection reports or test certificates for pressure integrity and material compliance.
Logistics for choke valves require careful planning due to their size, weight, and sensitivity to damage. Clarify Incoterms (e.g., FOB, CIF) and shipping methods, as these components often require specialized crating and handling. Lead times can vary significantly based on customization, so request a realistic production schedule and confirm payment terms, including milestones for progress payments.
Quality checks should include hydrostatic pressure testing, dimensional inspections, and material verification to ensure compliance with API 6A and other relevant standards. For critical applications, consider witnessing factory acceptance tests (FAT) or engaging a third-party inspector. Ensure all documentation, including material traceability records and compliance certificates, is provided to meet regulatory and operational requirements.
