Hydrogen as an energy carrier continues to be investigated as a form of energy for a more sustainable world. This tiny molecule poses challenges in its use and distribution.
A recent Emerson press release, New Emerson Pressure Relief Valve Optimizes Safety and Performance in Critical Gas Applications describes the Anderson Greenwood Type 84 valves, which deliver leak-tight service at very high pressures for hydrogen storage, transport, and refueling stations.
These pressure relief valves (PRVs) are:
…specially designed to protect tanks and vessels used in hydrogen and other high-pressure gas applications. With Arlon® 3000XT* thermoplastic seating and ASME SA-479 Type S21800 stainless steel spindle material, the Type 84 PRV delivers exceptional leak-tight performance, resistance to embrittlement, optimum seat tightness, high reliability and long service life.
The Type 84 PRV is designed to ensure the safe and reliable operation of H2 storage and transportation, H2 refueling stations, and other high-pressure gas applications in the Hydrogen, Air Separation, and Oil & Gas industries.
Hydrogen and helium applications up to 20,000 psig (1379 barg) and other high-pressure gas applications up to 21,756 psig (1500 barg).
Here is a closer look at the components within this high-pressure, direct-spring PRV.
This PRV complies with API 527, providing 90% seat tightness, and is certified per ASME Section VIII and XIII/NB capacities for gas.
