Recommended sealing materials for valve seats

Written by Marketing Digital on 14/02/2018. Posted in Estanqueidad estática.

As a continuation of the series of articles on valves published in our blog “Some valve sealing solutions”, “Certified O-rings for valves“ and “Elastomers resistant to aggressive fluids in valves”, this new article delves into another aspect of valves, in which we will explain which materials you should consider when choosing valve seats. Examples of valve seats Ball valve For example, in a ball valve, the control element (ball) rests on the seat and rotates on the seat when the valve is opened or closed.

75FKM 260466, new elastomer compound for motors and gearboxes

Written by Marketing Digital on 07/02/2018. Posted in Estanqueidad para equipos rotativos.

In today's article we present a special innovative solution in the field of elastomers, the material 75FKM 260466. It is a new FKM fluorine rubber compound, developed by our partner Freudenberg Sealing Technologies, whose special formulation extends the life expectancy of the seal considerably. It is a material that is much more resistant to synthetic oils, especially polyglycols and biodegradable lubricants, which have a critical impact on seal life expectancy, raceway wear and axle marking. ...

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

Written by Marketing Digital on 24/01/2018. Posted in Información técnica.

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.
