Manual Drive Adjustable Choke Valve The main application is to regulate flow and pressure. There are two kinds of valves: Positive and adjustable. There are three kinds of valves in adjustable choke valve: Needle plunger piston and hole plate. According to the Operation form, there are manual drive and hydraulic drive. The standard: API Spec 6A and SY/5127 The characteristic: The principle of Manual drive Adjustable choke valve is hydraulic energy consumption

Carbon Steel Choke Valve Positive Type It is installed in the X'MAS tree or wellhead, as flow regulator. In order to control the flow capacity, we shall alternate the choke bean of different DN. The Structure: Pressure-containing parts are made of alloy steel with sufficient tensile strength to ensure the safety and reliablity of the valve under pressure. The choke beans are made of alloy steel with the characteristics of hard wearing. Standard: API Spec 6A and SY/5127 Swing,
