Matched thermal characteristics

Matched thermal characteristics

Metal seated ball valve performance depends heavily on coated surfaces. That is why Remington Valve engineers each valve we build to handle the movement of materials, coated and un-coated, under temperature and pressure. Exacting tolerances in machining and assembly provide unequaled function and performance.

Matching thermal expansion characteristics in coated parts is critical to valve longevity and shutoff. The coating thermal expansion rate is closely matched to base material expansion rate to reduce the stresses experienced between the surfaces. When the ball and seat grow the coating grows with it. Reducing the chances of de-lamination of coatings and providing a sealing surface that withstand thermal variances.

Reducing the chances of valve seizure, Remington engineers thermal expansion gaps into our valves to provide performance and reliability whether the temperature is minus 50 or 1500 Degrees F.
