Quick-Change™ Orifice Plate Wellhead


Wellhead 2 inches


A Revolutionary Design Just Got Better!

QED’s revolutionary Quick-Change Orifice Plate Wellhead (U.S. Patent No. 8,800,597 & Patents Pending) combines easy plate exchanges for more accurate flow measurement with precise adjustment of gas flow, especially at very low rates (under 10 scfm).

Changing to the correct orifice plate takes only seconds, with no time wasted shutting down the control valve or retuning the well. The removable dust cover permits easy confirmation of plate size, giving you the highest confidence in your flow measurements.

The Precision Fine Tune™ Control Valve provides rigorous control of gas flow. Unlike traditional “gate” type valves, this unique design achieves a more linear flow rate adjustment across the entire range of valve movement.

All-new construction of molded, glass-filled polypropylene boosts strength and upgrades resistance to harsh field conditions, significantly increasing wellhead durability. Additional improvements, including easier hose fitting and simpler service, save valuable field time and help reduce maintenance and labor costs.
