CONVAL®- the PC software for engineers, planners and operators of industrial plants.

CONVAL® integrates extensive calculation functionalities for components and processes in industrial systems, based on tried-and-tested methods, such as DIN, VDI, VDMA EN/ISO and ISA. By strictly avoiding all forms of dependence on equipment manufacturers, CONVAL® guarantees flexible, professional working.

The range of available calculations extends from control valves, differential pressure primary devices, through to piping systems and heat exchangers, including integrated property calculations (based on a property database) and comprehensive databases for control valves, safety valves, materials, etc. as standard.
