Field tested and proven to increase service life when compared with other OEM choke options, the NX1 is rated up to 15,000 PSI CWP and has a 1-inch maximum orifice. During testing, the NX1’s internal trim components performed twice as long as other OEM brands. Additional features include both digital and local visual trim position indication and a wide range of hydraulic choke control console options.
CORTEC has successfully completed the field trial of the new remotely operated NX1 model hydraulic choke. The NX1 is an ideal option for applications requiring a compact 2” 1502 choke layout where remote operation is preferred. Designed to fit within the place of a standard 1502 Choke Tee, the NX1 is easily adapted into existing manifolds. The Choke is offered with a range of union or flanged end connections. This lightweight design offers a 1” maximum orifice and is rated up to 15,000 PSI CWP.
Field testing has confirmed substantial increased service life during harsh flowback operations when compared with other OEM choke options where CORTEC internal trim components have lasted more than 2X longer during the same testing period. Additional features include both digital and local visual trim position indication and a wide range of hydraulic choke control console options.
This design requires minimal maintenance and can be easily serviced by the end user in the field.
