Selection and supply of shut-off, control and safety valves

BESTFLOW GmbH provides technical selection and supply of industrial pipeline valves and related components for a wide range of process plants.

Main equipment categories:

• ball valves;
• gate valves;
• diaphragm valves;
• plug valves;
• piston valves;
• butterfly valves;
• safety valves;
• steam traps;
• pneumatic, electric and hydraulic actuators.

Supplies include products from manufacturers of industrial valves, steam and condensate equipment, and rupture discs. The specific design is selected according to the intended use, operating parameters and plant requirements.

Calculation of operating parameters and compatibility checks

When selecting control valves, flow rate, pressure drop, flow characteristics and operating conditions are taken into account.
Depending on the task, calculations may be performed using flow coefficients Cv/Kv, together with an assessment of cavitation conditions and actuator force or torque requirements.

Digital tools, including solutions based on artificial intelligence, may be used to identify components, analyse technical documentation and search for possible equivalents.
Selection results are verified against available technical data and documentation from manufacturers.

The availability of material certificates, for example per EN 10204, PMI reports, ITP/FAT documentation and the possibility of third-party inspections depend on the specific product and order requirements.
The need for and scope of such documentation are agreed during preparation of the supply.

Identification, equivalents and modernisation

BESTFLOW GmbH provides technical support in the selection of industrial pipeline valves, the replacement of components in existing installations and the search for equivalents of obsolete or discontinued equipment.

Depending on the task, the work may include:

• identification of installed equipment and verification of technical specifications;
• search for original components and alternative products;
• cross-referencing of designations and technical characteristics;
• analysis of technical, operational and design documentation;
• selection of pneumatic, electric and hydraulic actuators;
• coordination of technical parameters and organisation of international deliveries.

Whether a replacement is possible depends on the technical characteristics of the component, the operating conditions and the requirements of the specific installation.

Industrial plants and process applications

Industrial valves and related components are selected for use in various industries, taking into account operating parameters and the requirements of the specific project.

• Shipbuilding and offshore — valves for marine installations, taking into account project requirements and applicable classification society rules.
• Power generation and steam systems — safety valves and condensate removal equipment.
• Chemical and petrochemical industry — valves made of corrosion-resistant materials and with protective linings for the relevant process media.
• Oil and gas and extraction — shut-off and control valves for specified operating conditions.
• Refrigeration and vacuum systems — specialised valves for refrigeration, cryogenic and vacuum systems.
• Metallurgy, mining and the pulp and paper industry — valves for process operations and production plants.
• Automotive and mechanical engineering — valves for production lines and test benches.
• Laser technology and automation — control valves for the corresponding process systems.

Equipment is selected on the basis of technical requirements, available documentation and operating conditions.
