Elastomers resistant to aggressive fluids in valves

Written by Marketing Digital on 31/01/2018. Posted in Estanqueidad estática.

Due to the complexity that characterizes the process industry, fluids that can be aggressive for valve sealing elements, such as O-rings, are often used. This is explained in another article published in our blog: “Some valve sealing solutions”. O-rings are manufactured from elastic materials, also known as “elastomers”. The most common elastomer materials are usually: - Synthetic rubbers such as e.g. EPDM and NBR. - Silicone rubber (VMQ). - Silicone rubber (VMQ).

Selection of elastic materials for hydraulic oils

In hydraulic circuits, experts use fluids as power transmission elements that also serve to lubricate, cool and seal clearances between elements. The lubrication and cooling capacity of hydraulic fluids such as oil are the most important characteristics to prevent wear between moving parts. Viscosity in hydraulic oils Another of the most important characteristics for selecting the hydraulic fluid is the viscosity, which must always be interpreted in relation to the temperature and pressure of the hydraulic system.

Certified O-rings for valves

Valve O-rings are a sealing solution for the stem of a spindle valve, as we explained in another article published in our blog under the name “Some valve sealing solutions”. Depending on the valve's service, its documentation will be required to include certificates of critical components for the valve's operation, as, for example, is the case of elastomer O-rings. It is common in the oil and gas industry that it is mandatory that the O-rings for valves to be used in the oil and gas industry must have the following certificates...

Some valve sealing solutions

Depending on the nature of the fluid flowing through a pipeline, you must choose one valve or another to manage it along the line. Thus, you can install ball valves, shut-off valves, angle seat valves, butterfly valves and flap valves, among others. Both the type of valve and the working fluid determine which engineered sealing solution should be chosen to prevent possible leakage episodes. These solutions are based on O-rings, flat gaskets, profiles, graphite shaped rings, gaskets and energized gaskets. Sealing solutions...
