STV-4 Series Rotary Lock Traveling Valve Eliminates ALL Gas Lock! Stinger Oil Tools STV-4 Series Rotary Lock Traveling Valve Eliminates ALL Gas Lock!

www.stingeroiltools.com | sales@stingeroiltools.com PRODUCT DESCRIPTION Used In Artificial Lift Wells Which Utilize Rod Pump Configuration Completely Replaces The Traditional Ball And Seat Traveling Valve Upper Threads Connect Directly To The Valve Rod Lower Threads Connect Directly To The Plunger www.stingeroiltools.com | sales@stingeroiltools.com

www.stingeroiltools.com | sales@stingeroiltools.com BENEFITS Eliminates ALL GAS LOCK Increases Production Allows Pumping Under Extreme Bottom Pressure Without Loss of Fluid Efficiency Reduces Operating and Well Servicing Costs Oversized Internal Ports Allow Debris to Pass Through Valve (i.e. Sand and Paraffin) www.stingeroiltools.com | sales@stingeroiltools.com

www.stingeroiltools.com | sales@stingeroiltools.com VALVE PLACEMENT Available sizes range from 1 ½” to 3 ¾” Seating surface and valve body engineered to withstand 2 years of constant service Units can be customized to accommodate clients’ individual production string configuration Valve components engineered to withstand well depths of 18,000’ www.stingeroiltools.com | sales@stingeroiltools.com

www.stingeroiltools.com | sales@stingeroiltools.com PROVEN RESULTS Consistent suction and fluid recovery on every stroke Valve increased production from 25 bbls/day to 40 bbls/day Fluid recovery dropped to 9.3 bbls until fluid filled cavity below. Gas relieved from well Higher gas pressure noticed @ 22.2 bbls No gas lock. Valve pumped off gas instead of locking up Graph shows consistent gas pressure relief on every down stroke www.stingeroiltools.com | sales@stingeroiltools.com

www.stingeroiltools.com | sales@stingeroiltools.com ELIMINATES GAS LOCK Gas lock occurs in traditional ball and seat valves when the gas is trapped inside the valve, not allowing the ball to come off of the seat. With the STV-4 design there is no ball and seat. It uses a patented helical spiral that actuates open and closed when pumped, regardless if gas is present. www.stingeroiltools.com | sales@stingeroiltools.com

www.stingeroiltools.com | sales@stingeroiltools.com INCREASED PRODUCTION Can Increase Output 12 – 60% over Traditional Ball and Seat Valve Design Begins Suction at a Maximum 2 Inches of Rod Movement Increase in Fluid Production Due to Valve Closing Sooner than Conventional Ball and Seat Pull Stroke STV-4 Design Needs only 2” max to create suction Nearly full stroke of productivity Less efficiency = lost production = less payout Other / Standard designs Pull Stroke Up to 2’ before suction BEGINS www.stingeroiltools.com | sales@stingeroiltools.com

www.stingeroiltools.com | sales@stingeroiltools.com FLUID EFFICIENCY Efficient Under Extreme Stress No Issue of Ball Displacement Due to High Bottom Pressure Engineered Rotary Locking Action Prevents High Bottom Pressure Blow-By on Upstroke Prevents Loss of Fluid Recovery By Locking Open on Down Stroke www.stingeroiltools.com | sales@stingeroiltools.com

REDUCED OPERATING COSTS The STV-4 Eliminates These Typical Cost Factors Typical / Frequent Workover Causes Wear and tear on the ball and seat of traditional valves Gas lock encountered due to cavitation and gas pocket ingestion Frequent Service Calls Due to Inconsistent Lifts and Equipment Failures Fatigue on Prime Movers Tension on Traditional Stress Points www.stingeroiltools.com | sales@stingeroiltools.com

COMPETITION COMPARISON STV-4 SERIES design Other / Standard designs Superior Materials Used Superior Manufacturing and Machining Processes Eliminates Gas Lock Reduces Operating and Well Servicing Costs Increases Production Increases in PROFITABILITY 60+ year design with inherent problems Made of inferior materials Prone to GAS LOCK Frequent valve changes needed in H2S wells Same output = same production Same problems = same lost production and profits www.stingeroiltools.com | sales@stingeroiltools.com
