Valves for Textile Chemicals Special Valves for Special Applications: There's Two for Every Case

Industrial valves in textile chemistry—A variety of different valves lead to widely differentiated overhaul expenditure and is associated with an extensive stock of spare parts. In case of a textile producer it was possible to focus essentially on compact ball valves and V–port segment ball valves.

The manufacture of textiles has been known for thousands of years and is an important characteristic of human culture. Textile products — besides everyday articles, including the diverse textile materials for technical purposes — are manufactured from both natural and synthetic fibres and their mixtures. In many textile industry companies, the route from raw material to the ready–to–use finished product involves numerous concerted mechanical and chemical treatments in order to give the goods the required user properties, the specific character and a typical and fashionable appearance.

Textile chemistry addresses chemical problems that arise in the industry during the processing of fibres. Textile auxiliary agents are special chemicals for the wide range of processing steps which ensure a trouble–free and effective production process. As a further chemical challenge, these substances must neither be toxic nor inflammable and must not pose any ecological problems.

The consequences of this are high requirements in the production of the industrial valves that are used. The Textilcolor Company in Sevelen, Switzerland, a company experienced in handling these requirements, is a good example to demonstrate the benefits of specifically used valves.

Special Material Demand Special valves

At Textilcolor, particular attention is paid to safety aspects, reliable leakproofness of the valves and the resistance of the valve materials used with regard to durability and quality of the products that are being manufactured. The chemicals used during processing, such as stearic acid, paraffins and other chemical raw materials, place different requirements on the equipment.

In the past, the company used a variety of different valves. This led to widely differentiated overhaul expenditure — and overhauling always means an interruption in production, a shut–down and costs. One should also not forget infrastructure products such as hot water and steam. These media admittedly do not pose any special challenges to the valves, but they involve other types such as flaps and on/off and control valves.
