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.

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.
