To ensure an economical system productivity, it is necessary to keep the operation, maintenance and servicing costs at a minimum. At the same time, increasing cost pressure leads to higher expectations toward technology, quality and service and more comprehensive and stringent statutory provisions.

The VARIVENT® system’s modular design makes it possible to individually adjust control valves to specific process requirements. This results in economic efficiency for the system operator, optimized stock keeping, and cost-effective spare parts production due to the low diversity of parts.
 
The integration of the control valves into the process control technology has a decisive impact on the quality of the control and the product. Preventive maintenance of the control valves ensures the system's high availability.
