GSR Ventiltechnik has developed a new valve series for the hydrogen sector. The direct-pressure controlled valves are characterized by a long service life, which is achieved by the unique design of the stem seal. It enables 35% more switching cycles than comparable competitive products.
The generation of electricity from wind and solar power plants will be massively expanded in the coming years. However, since these forms of electricity generation are subject to fluctuations due to the time of day and weather conditions, and the electricity generated cannot be stored easily, new concepts are still needed here. The production of green hydrogen from the surplus electricity of renewable energy plants could be the solution. Hydrogen can be temporarily stored, transported and used in gas grids, or converted back into electricity in gas turbines.
This green hydrogen is produced by splitting water (H2O) into hydrogen (H2) and oxygen (O2) using electrolysers and renewable electricity. The new externally controlled valves from GSR control the processes surrounding electrolysis.
A version for use in both the hydrogen and oxygen processes will soon be available. The body materials have been specially qualified for use with H2 or O2. The hydrogen version has reliable, tested sealing elements, while these are even BAM-certified for the oxygen version.
The valves are optimally designed for the prevailing pressure and temperature ranges, have excellent flow characteristics, and feature sophisticated materials that ensure a long service life.
They have high tightness (10-6 mbar l/s) and are ATEX certified. SIL2 acceptance is planned.
