Density. Concentration. Flow rates. Liquid levels. Those are just a few of the parameters regulated by controls and valves found in countless types of processing equipment used in industries and municipalities. Components such as positioners, actuators, valve controls, and pressure regulators must be of the highest precision to deliver reliable performance in critical operations. Components manufactured with Swiss screw technology provide an added measure of confidence throughout the control loop.

Swiss screw machines create components of unparalleled accuracy in addition to a number of other advantages for control and valve manufacturers.

Critical tolerances – Valve bodies and related control accessories must meet tight tolerances to ensure proper liquid flow. Swiss screw technology provides superior tolerances in these components through better support for all stock material during the manufacturing process. That’s because the part moves while the tooling is stationary, resulting in reduced risk of the support material moving for precision accuracy in meeting required tolerances. 

Component geometries – Hardware found in controls and valves varies as much as the types of control processes. Swiss screw machines can produce a broad range of these complex, intricate parts faster and with extraordinary precision. The key is the technology’s capabilities for up to 6-axis machining, including an additional rotation around the Z axis for faster cut times. Swiss screw machines also offer positioning for component feature contouring that might otherwise have to be machined separately.

Material versatility – Materials used in control and valve applications must stand up to a variety of liquids including harsh chemicals and other solutions. Swiss screw machining can be used to machine the materials required such as stainless steel, aluminum, titanium and a range of alloys. 

Unmatched accuracy – Swiss screw machining offers the dimensional control and other properties required by the many different kinds of automotive parts. That’s because the technology provides better support for all stock material – the part moves while the tooling is stationary. The result is reduced risk of the support material moving for precision accuracy.
