2 What's in a ball valve? An efficient and reliable process demands quality products. This includes the important function of flow isolation. If inferior products are used, breakdowns and expensive production losses can occur. Spirax Sarco provide high quality, reliable products which ensure you get the best out of your process. Protect your process or plant with perfect isolation: Ball valves from Spirax Sarco. Corrosion resistant bodies Blow out proof stems protect the operator and prevent emission losses Tight shut-off guaranteed Flexible seats maintain sealing at low torque under all conditions Every ball is manufactured by us to stringent specifications for shape, hardness, and surface finish:.127 µm. This attention to detail reduces friction and wear on the ball and seat ensuring reliable, smooth operation and a long service life. 2
