Valve Inserts are a critical part of any pumping operation. QRS offers high performance valve inserts for the well service industry in two sizes, 4” OD and 5” OD, and produce any custom color your operation requires.
QRS uses only the best Urethane available that is superior to anything else in the market place. Our urethane compared to competitor’s compounds is highly abrasive resistant.
Acidic fracturing fluid can plasticize polyester, causing a breakdown of mechanical properties, leading to poor sealing of the valve and premature failure.
