Texsteam TA 7170 – Valve and Seal Component

TA 7170 is a Texsteam internal valve and seal component for chemical injection pumps in the 1200, 3700, 4300, 5000, and 5100 Series. The TA-series encompasses check valve balls, springs, valve discs, O-rings, inlet and outlet bodies, stuffing box seats, and small precision internals that govern the directional flow and leak-free operation of each pump stroke.

In chemical injection service, internal valve components experience repeated pressure cycling against aggressive fluid chemistries — corrosion inhibitors, acids, methanol, and scale inhibitors. Worn or damaged valve balls and seats cause back-leakage that degrades metering accuracy and can allow corrosive chemicals to migrate into unintended pump zones. Replacing with the factory-correct TA 7170 restores the tight shut-off and proper cracking pressure specified by Texsteam engineering.

Manufactured at the Baker Hughes / Dresser Texsteam facility in Houston, Texas, TA-series parts have been produced to consistent tolerances since the company’s founding in 1937. Each component is dimensioned to match the exact bore, thread, and seat geometry of the target pump series. Use part number TA 7170 for a guaranteed fit and to maintain the original pump performance specification.
