Choke Valve

Choke valve, a valve that raises or lowers a solid cylinder which is placed around or inside another cylinder which has holes or slots. Used for high pressure drops found in oil and gas wellheads

Choke Valve Wellhead China can be divided into straight-through type and angle type according to the channel mode; according to the shape of the opening and closing parts, there are three types of needle, groove and window.
Adjustable throttle valve: the valve needle and valve core are made of hard alloy, and the product is designed according to API6A standard, which has the performance of wear resistance and erosion resistance. Mainly used for wellhead oil (gas) tree equipment.
Sliding sleeve throttle valve: The valve core adopts a low-noise balanced structure, which is easy to open. The product is designed according to API6A standard. The surface of the valve core is covered with tungsten carbide. It is suitable for demanding conditions such as flashing, high pressure difference, high pressure, and cavitation. On occasion, the service life is long, and the flow adjustment accuracy is greatly improved. It is suitable for oil, natural gas, chemical, oil refining, hydropower and other industries.

At Yulin, we specialize in designing, manufacturing, and supplying high-performance Adjustable Choke Valves for the oil and gas industry. Our valves are engineered to precisely control wellhead flow pressure, ensuring safe and efficient operations across various oilfield applications. With an emphasis on durability, performance, and ease of use, our adjustable choke valves play a vital role in optimizing production rates and maintaining the highest standards of safety and efficiency.



What is an Adjustable Choke Valve?
An Adjustable Choke Valve is a specialized valve used to regulate the flow of fluids and gases at the wellhead. It is designed to reduce the well flow pressure to a manageable level, allowing upstream equipment to operate safely and effectively. By precisely controlling the flow of production fluids, the adjustable choke valve helps to prevent issues such as sand production, pressure surges, and equipment damage.

These valves are essential components in a variety of critical oilfield equipment, including wellhead assemblies, Christmas trees, choke manifolds, desanders, inline heaters, and other production and processing systems. With its versatile design, the adjustable choke valve allows operators to modify the choke size as needed, offering a dynamic solution for ever-changing field conditions.
