Series of requirements for hydraulic valves

High resistance to creep, corrosion and yield are all requirements to be met by hydraulic valves and are essential for operating efficiency.

To ensure the safe use of the hydraulic valves, the engineers of Gnali Bocia, a leading company in the sector of connecting elements, have to meet the design demands of the components to be sized. The process starts with selection of materials, which already implies a first selection of the characteristics of the hydraulic valves. In fact in environmental conditions, a material has a specific resistance to yield, as well as a specific Young modulus and strain limit: all of these also represent the reaction of the material to temperatures. Another important parameter is the trend of these characteristics applicable to hydraulic valves according to the specific temperature: on any increase in temperature the reaction of the metal may pass from fragile to elastic and this must be taken into account to ensure the correct design of a valve. Temperature also strongly influences the phenomenon of creep. This effect modifies the resistance capacity of a component on any increase in temperature, causing the structural failure of the valve if subject to even normal loads, but at critical temperatures. Normally this involves a temperature of approximately 40% of the melting temperature, although this can vary according to the load applied on the hydraulic valves.
