GSR Ventiltechnik GmbH & Co. KG has developed a new valve series for the hydrogen sector. The direct-pressure controlled valves are characterized by a long service life, achieved through the unique design of the stem seal, enabling 35% more switching cycles than comparable competitive products. The new externally controlled valves 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.
