Chemical industry

We do not have to think hard to recognize the ever-presence of chemical substances in our everyday lives. Valves from Schubert & Salzer Control Systems are used in the often complex manufacturing processes. These are predominantly sliding gate valves, ball sector valves, segment disc valves and angle seat valves.

Here they are used, for example, in the production of hydrogen fluoride (in the case of this and other hazardous media, it is preferable to use Schubert & Salzer valves with a metal bellows since this provides a 100% seal to the exterior), desiccant manufacture, the production of plastics, in the dosing of resins or the metering of dyestuff suspension with solids content.

Numerous and diverse applications can be found: Schubert & Salzer valves control the heating and cooling of reactors, they are used in the generation and processing of steam, precisely controlled chemicals or liquid paints, or carry out the regulation of plant air or vacuum.

Often, chemical processes place heavy demands on resistance to media, requiring the use of special materials, such as Hastelloy. Besides the traditional, robust angle seat valves especially sliding gate, ball sector and segmented disc valves perform in these challenging applications and deliver high control accuracy at the same time.

A good example of such an application is the production of ultra pure sulphuric acids and other ultra pure chemicals. During the acid dilution process sliding gate valves perform particularly well as they can be used even in concentrated alloys and other exotic substances like PTFE (Teflon), glass, platinum or gold.. Flow variations of up to 100% can be compensated for without compromise. For more information on this, read the user report on PVS Chemicals.

The high control accuracy, long service life, compact design and easy maintenance of the Schubert & Salzer ball sector valves is relyed on by reputed producers of engineering resins. The unique ball sector feature a self-cleaning function and are particularly suitable for abrasive, crystallizing or viscous fluids.
