Applications

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.

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.

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.
