Choke Consoles are available as single or dual choke control units and with standard pressure gauges or state-of-the-art digital gauges. The single choke control console is precision built to provide accurate pressure control, yet is built to withstand the harshest conditions. It operates either hydraulically or manually and is self-contained and skid-mounted for easy installation on or near the rig. A key feature of the console is the large easy-to-read gauges which monitor critical drill pipe and casing-pressure. A choke position indicator shows relative plate opening from full open to full close. Dual Choke Control Console provides a separate valve to regulate chokes from independent hydraulic systems during special applications. An operator has full command of both chokes without switching controls.
Choke Valves are valves that lift a solid cylinder up and down which is placed around or inside another cylinder, which has, holes or slots. The design of a choke valve means fluids flowing through the cage are coming from all sides and that the streams of flow collide with each other at the center of the cage cylinder, thereby dissipating the energy of the fluid through flow impingement. The main advantage of choke valves is that they can be designed to be totally linear in their flow rate. Heavy-duty industrial choke valves are used in the oil industry and for highly erosive and corrosive purposes. Choke valves are important for carbureted gasoline engines because small droplets of gasoline do not evaporate well within a cold engine.
