Valve solutions for hydrogen applications

Thursday, April 1, 2021
Hydrogen is considered to be a versatile energy carrier of the future that does not emit direct greenhouse gases in use. At the same time, the medium hydrogen places high demands on valves. Hydrogen is the lightest element in the periodic table, has a high gravimetric energy density and can lead to material embrittlement under certain conditions. Key aspects to be considered when selecting valves for use in hydrogen are outlined in the following article:

Advanced environmental protection – the ZETRIX way!

Tuesday, March 1, 2016
Both TA-Luft [1] and DIN EN ISO 15848-1 [2] [3] aim to mitigate or reduce fugitive emissions which are harmful to the environment and human health. TA-Luft is a comprehensive German regulation which specifies binding technical requirements for classified installations in accordance with the 4th Federal Emmission Control Act. EN ISO 15848-1 [2] [3] is an international standard which provides users with evaluation criteria for classifying valves (isolation and control devices), to enable different designs or brands to be compared. Although compliance with the requirements of TA-Luft is considered to be proof of a sealing system’s quality –not just in Germany but in many other countries too – EN ISO 15848-1 [2] [3] is playing an increasingly important role in the chemical, petrochemical and process industries.

Operational Behaviour of Safety Valves with Constant Superimposed Backpressure

Wednesday, April 1, 2015
When selecting spring loaded safety valves, an accurate knowledge and consideration of the specific operating conditions are vital to ensure that these devices work reliably. As optimal resource use becomes an increasingly relevant criterion, plant owners focus particular attention on components that can be depended on absolutely – even at their physical limits. In the design of a safety valve, the existence of a backpressure must be considered in addition to the usual parameters for dimensioning. In this present report, the function of a safety valve is intended to be shown when a constant superimposed backpressure is present in the discharge and thus acts against the direction of opening of the safety valve.
