The Pruitt Lite™ MPD Modular Choke system is designed to be configurable to the customer’s needs. It’s comprised of separate bolt-on units; two 3” electrically actuated linear drilling chokes, one 4” programmable Pressure Relief Valve (PRV), and one 4-1/16” full-bore bypass. The full system incorporates two HMI (human machine interface)/PLC (programmable logic controller) control systems that provide 100% back up in functionality. The Pruitt Lite™ MPD Modular Choke system can be supplied as a full system or individual components.

Example: basic Set Point Pressure Control could be one 3” electrically actuated drilling choke and the 4-1/16” full-bore bypass. In this configuration, only one HMI/PLC control system is supplied as standard.

The intelligent PRV can be set up to have both a Hi-Hi (max set point) and a tracking Pressure Variable set point to protect both surface equipment and the formation.
