Winged Collar Makes Changing Orifice Plates Even Easier

QED has redesigned the collar on the Quick-Change™ (U.S. Patent
Number 8,800,597 & Patents Pending) Orifice Plate Wellhead to now have wings. This makes the collar more ergonomic and even easier to turn when making orifice plate changes.

Changing plates in the Quick-Change Orifice Plate Wellhead is as easy as 1, 2, 3 and requires no tools – quickly release the orifice plate with a half-turn of the winged collar, change the plate, and close the collar. The winged collar is molded in QED’s distinctive yellow color making the whole Wellhead more visible even in low light.

The Quick-Change Wellhead combines easy plate exchanges for accurate flow measurements with precise adjustment control over a broad flow range. Using the most appropriate size orifice plate and achieving a pressure drop of 0.5” – 5.0” of water column is essential to generate stable flow readings with the best resolution. The Quick-Change Wellhead’s accessible plate housing allows for easy confirmation of plate size and placement giving you the highest confidence in your flow reading and eliminates reporting errors. See how quickly you can change to the correct orifice plate in our Quick-Change™ Orifice Plate Wellhead movie.
