Ball valve applications

The application and the process fluid characteristics are the main factors in selecting a valve type and construction materials: clean fluids generally allow a wide range of valves and materials, while for dirty fluids and high risk applications the choice is limited to few valve types and selected materials: the right, conscious and diligent selection of both non-metallic and metallic materials along with their proper handling are very important issues from a safety viewpoint. There are many difficult applications which are challenging to the valve’s ability to provide acceptable duration and performance, ERREESSE production program offers both control and isolation ball valves designed to appropriately handle severe service applications, whether applications are corrosive with acid solutions or have higher cycle frequencies and higher pressure and temperature. Special X-TRIM design to suit extreme applications!

 

Ball valve applications - High Pressure
High Pressure Ball Valves

20 bar to 1030 bar
Design pressure from 20 bar(g) to 1035 bar(g), in combination with other service conditions in hydrocarbon processes, refining, petro-chemistry, determinates ball valve construction and material selection.

0° to 120°C (32° to 248°F)
Instrument air, diesel oil, lube oil, demineralized water, steam, nitrogen and other produced gas are considered as clean services for utility applications: low pressures applications, on top side above ground and below ground installations, from 0° to 120°C (32° to 248°F), carrying standard non corrosive and clean fluids, free from solid particles or aggressive contaminants, providing just a service to main processes.

Aggressive and solid contaminants
Corrosion is a gradual loss of material by chemical or physical reaction with the process fluid; depending on concentration, temperature and pressure drop the exposed to fluid surfaces can be seriously damaged impairing the performance of the valve, unless the correct valve type and materials are selected.

High Temperature Ball Valve
High Temperature Ball Valve

121° to 1100°C (249,8° to 2012°F)
Heating to boiling points, catalytic and hydro-treatments are some of the refining processes necessary to separate crude oil into storable fractions like marketable oils and condensate; most of these processes at high temperature, from 121°C to 1100°C (249,8°C to 2012°F). Erreesse can provide valves engineered to withstand and exceed high temperature applications with specific constructions and duly selected materials also suitable for geothermal applications, where the direct use of steam, hot water, with abrasive and highly corrosive chemicals and minerals could foul, erode, and damage standard equipment, offering unique features that make them an excellent choice for hot water (geothermal brine) and similar services.

Low Temperature Ball Valve
Low Temperature Ball Valve

0° to -50°C (32° to -58°F)
When Natural Gas has to be separated into fractions or treated to protect equipment from contaminants (acids), first stage of sweetering and acid removal at 0° to -50°C (32° to -58°F), are the pre-cooling processes necessary to do that before gas liquefaction stage; propane or a mixture with other gases in small quantities is the cooling element. Erreesse valves range offer a wide selection of models suitable for low temperature applications.

-51° to -196°C (-59,8° to -320,8°F)
When Natural Gas has to be separated into fractions or treated to protect equipment from contaminants (acids), sweetering and acid removal at -51° to -196°C (-59,8° to -320,8°F), are the final stage to do that, starting from liquefaction to sub-cooling stages, with pure or mixed refrigerants (methane, nitrogen) as cooling elements. Erreesse production program offers special valve solutions engineered to suit cryogenic processes with specific constructions and duly selected materials.
