Solutions for chemical process technology

Valves, measurement and control systems for chemical processes

GEMÜ's plastic and metal products are successfully used for distributing, handling and dosing chemicals and other liquids, vapours and gases in the chemical industry and environmental systems.

The varied processes in industrial chemicals plants often have stringent requirements for the valve technology employed. High temperatures, high pressures and critical working media require very specific valve solutions and components. We have been offering precisely these solutions for decades, supporting our customers in fields such as electroplating, waste incineration or chemicals production.

GEMÜ's plastics expertise for industrial valves

In many cases, it is not possible to use a valve with metal body for applications in the chemical industry or environmental systems, as the corrosive medium attacks and potentially destroys the material. A plastic body may therefore appear a more logical alternative. However, this is not always a viable option, since the temperatures and pressures encountered are higher than the material will allow.

Do you have problems with particulate matter?

It is not uncommon to reach the performance limits of components in chemical processes. This also applies when conveying media containing particulate matter. Most ball valves quickly reach their design limits in this area.

Plastic-lined diaphragm valves, originally designed for media containing solids in suspension, represent one solution to this.

Increasing operational safety, while simultaneously lowering operating costs

Servicing work on diaphragm valves, which essentially comprise three main components, is quick and easy to perform thanks to their design. The wearing part – the diaphragm – can be replaced in a matter of seconds by simply undoing a few screws. Unlike ball valves, for example, the valve does not need to be removed radially here.

As is also the case in aseptic applications, preventive maintenance work allows uncontrolled system shutdowns to be avoided. Production waste, rejects and downtimes can then all be reduced to a minimum, while system reliability can be improved.
