US Patent Number 8,800,597 and Patents Pending
QED’s Precision Fine TuneTM Control Valve (U.S.Patent Number 8,800,597) is a revolutionary
breakthrough in landfill gas well field tuning. Unlike tradi-tional “gate” type valves, this allows you to easily andprecisely adjust the gas flow from a well, rather than justturning the flow on or off. The valve design gives youthe ability to achieve linear flow adjustment across theentire range of valve movement.
The valve also has a high visibility metered scale thatallows you to observe the valve setting, andquickly and accurately return to theexact flow setting after ashutdown. The risingstem valve exposesmore of the meteredscale as it is opened,allowing you to see and record numericallyexactly how far thevalve is open.
The valve uses a “flow-tuned” design valve plug, whichallows for fine tuning even at very lowgas flow rates (under 10 SCFM).
The stainless steel ruggedvalve stem and glass-filledpolypropylene handle makethe valve much moredurable in the harsh outdoorenvironment to which landfillgas wells are exposed.
QED’s new Quick-ChangeTM Orifice Plate Wellhead(U.S. Patent Number 8,800,597 & Patents
Pending) combines easy plate exchanges for accurateflow measurements with precise adjustment control overa broad flow range.
The Quick-Change™ Orifice Plate (Patent Pending) fea-ture makes it as easy as 1-2-3 for the operator tochange to the most appropriate size plate for the given conditions. The accessible plate housing allows for easyconfirmation of plate size and placement giving you the
highest confidence in your flow reading.
Changing to the correct orificeplate can be done in seconds,and there is no time wastedshutting down the controlvalve or rebalancing the wellfield. These benefits all savevaluable field time and help
reduce labor costs.
The Wellhead’s control valve design allows youto finely control gas flow even at rates under 10 SCFM.This unique design will changethe way operators adjust gasflow. Wells can now be tunedby flow rather than by vacuum.Well Cap is sold separately.

Quick-ChangeOrifice PlateAdvantages:
• Saves time – plates canbe changed in seconds
• Accurate flow measur-ments – match the rightplate with the gas flow
• Reduces reportingerrors – easy to identifythe plate in use

Prior to the installation ofthe Fine Tune ControlValve, Well 90 (right) wasout of compliance.Oxygen concentrationhad increased to 6.4%and the balance gas con-centration spiked at48.4%. After installation,those concentrationshave been reduced, help-ing maintain compliancewhile gently increasingmethane production.

WELL CAPS
QED’s innovative StabilizerTM LFG Well Caps (US Patentnumber 9,068,421) feature a unique support ring
molded directly into the Cap that aligns and stabilizes the LFGwellhead. This takes pressure off the flexible coupling andthe flex hose and, along with watertight threads, reducesleaks from the wellhead. The caps are molded in a distinctive yellow*, which ensures you are receivinggenuine QED well cap.
This is the first engineered gas well cap that allows liquidlevel readings without removing the wellhead – faster, safer,less system disruption. Air introduction and gas release areminimized, eliminating the need to shut down the vacuum sys-tem for level measurements and rebalancing of the well field.
Well Caps without pumpfittings are a good wayto start on gas recoverywells. A pump fitting kit can be added laterfor dual extraction wells.
Designed to work with 6” and 8” diameterwells with 2” or 3” wellheads, all modelsprovide ports to accommodate a downwellpump. There is also an economy modelfor 6” gas-only wells.
Unique support ring featurehelps prevent wellhead leaks
StabilizerTM LFG Well Cap Advantages:• Support ring reduces wellhead leaks, minimizing air intro-duction and gas release
• Pump fitting kits allow conversion of gas recovery caps todual extraction

Solarguard™ Flex Hose from QED is made with UV-resistant flexible PVC with a rigid PVC helix. This uniqueformula extends the useful life of Solarguard hose overtypical clear PVC landfill gas flex hose. Tests have shownthat Solarguard hose maintains tensile strength and laststwice as long as standard PVC hose.
With Solarguard hose, you’ll save on both the cost ofreplacement hose and the labor costs of fixing air leaksfrom cracked hose. QED’s Banding Kits save you even more,with a lower purchase price, longer service life, and easierinstallation and removal than helical hose clamps, whichcan be expensive, difficult to use, and tend to corrode easily.The banding coils are uniquely designed to fit Solarguardhose, and use high strength, all stainless steel clamps,which are user friendly, durable, and far less expensive.

Low-maintenance pump lasts up to 10 times longer between service eventsand requires 50% less time to clean
Extended UptimeProprietary finishes reducebuildup and extend thetime between cleaning.
Minimized DowntimeThese special non-stickfinishes require less thenhalf the time to clean thantraditional pumps.
316 Stainless SteelAll metallic parts are 316-grade SS for greater corrosion resistance.
New and Improved Valve Stem ConnectionNo fasteners; no cotter pins.Exhaust seat is easy to adjust.
Field tests have shown that the New AutoPump®(Patent Pending) AP4 Ultra will last up to 10 timeslonger between service events. Tested in the mostsevere applications, the new pump ran longer and was easier to clean than a standard pump.
Several improvements contribute to this new longevity.The AP4 Ultra uses proprietary non-stick finishes onthe float and discharge tube to reduce solids buildup,extending the time between cleaning and making itmuch faster and easier to clean the pump. All metallicparts are 316-grade Stainless Steel, which has greatercorrosion resistance and can withstand attacks of theharshest leachate. This pump uses new and improvedvalve stem connections, no fasteners or cotter pinsare required. Some models have temperature ratingsup to 250 °F, making them ideal for high temperatureapplications.
“Cleaning has been an easy task, most times just requiring a water spray,” said one user. From another,“We removed residue with some clean water and aswipe of the hand.”
The Ultra builds upon the established AutoPump system, which has been the industry leader for over 30 years, and includes QED’s unmatched customer service.
