✅ Modular Configuration: Available in Single-Wing, Dual-Wing, and Water Injection designs.
High-Performance Xmas Tree Valves for Surface Production
Our Christmas Tree Valves (Xmas Tree Valves) are the critical control interface between the wellbore and the production facility. Engineered to the rigorous API 6A standards, our assemblies provide primary shut-off, flow regulation, and intervention access for oil and gas wells.
Whether you are operating in conventional onshore fields or demanding offshore environments, our Oil Well Christmas Tree Valves ensure maximum safety and integrity under extreme thermal and pressure cycles.
Essential Components & Configuration
A complete Christmas Tree Valve Assembly consists of integrated valves designed for specific safety and operational roles:
Master Valves (Lower & Upper): The primary safety barrier. Our manual or actuated gate valves provide a bubble-tight seal to isolate the wellbore.
Wing Valves: Located on the side of the tree to control flow into the production line or allow for well killing/injection.
Swab Valve: Positioned at the very top to allow vertical access for wireline or coiled tubing interventions.
Choke Valve: Precision-engineered to regulate the flow rate and control wellhead pressure.

Christmas Tree Valve: Frequently Asked Questions
Q: What is the difference between a Wellhead and a Christmas Tree?
A: The Wellhead is used to hang the casing and seal the well during drilling. The Christmas Tree is installed after completion to control and manage the flow of oil or gas.
Q: Do you offer PR2-validated valves?
A: Yes. We provide API 6A valves validated to Performance Requirement Level 2 (PR2) for high-cycle and high-temperature reliability.
