Product Description

H2 Positive choke valves are primarily used for controlling flow rates and pressures in wellhead and production operations. They are commonly found in drilling, testing, and production settings, as well as in Choke Manifolds, Single String Block Tree and Dual String Block Tree. These valves feature a fixed orifice, providing a specific flow rate, and are frequently used when precise flow control and pressure regulation are needed.

H2 positive choke valve controls flow rate in oil and gas operations by using a fixed orifice size, requiring disassembly to change the flow rate. Unlike H2 adjustable chokes that can be adjusted on the fly, positive chokes use a replaceable "bean" or orifice to set the flow rate. To change the flow rate, the valve must be taken offline, disassembled, and a different sized bean installed.

H2 positive chokes provide a fixed flow condition with a large selection of available bean sizes and types. Adjustable chokes provide variable flow rates but can be locked into position if a fixed flow rate is required. Combination bean and seat converts the adjustable choke to a positive/adjustable choke for bringing on the well slowly with the adjustable feature.

Once the desired flow rate is reached, the choke can be operated as a positive choke. This reduces wear on the wing or master gate valves because they are not used to control flow. In every application, the H2 choke delivers long life and low maintenance.
