A positive choke valve holds a single fixed size orifice bean locked into a housing, similar in principle to a fixed choke, but built with a quick change mechanism that lets operators swap the bean without disassembling the entire valve body. This positions the design between a fully fixed choke and a fully adjustable choke, giving the simplicity and reliability of a fixed orifice while still allowing the flow rate to be changed by fitting a different bean when production conditions shift. Positive chokes are typically paired with an adjustable choke in a manifold, providing a stable backup restriction while the adjustable choke handles fine control.

Common Applications

• Choke manifold service alongside adjustable chokes
• Applications requiring a stable, non varying restriction
• Fields where bean size needs periodic but not continuous adjustment
• Backup flow restriction for redundancy in production systems
