Emerson releases Anderson Greenwood Type 84 high-pressure relief valve for gas and hydrogen applications
The press notice emphasises the valve’s zero-leakage sealing technology, robust spring and trim materials rated for resistance to hydrogen embrittlement, and rigorous helium leak testing during manufacture to ensure integrity under high-pressure duty.
Emerson positions the Type 84 as addressing growing demand for reliable overpressure protection in hydrogen-ready infrastructure, and for gas-service equipment that must meet increasingly stringent safety and emissions requirements.
The company also points to digitalisation options for monitoring valve condition and set-point verification, supporting predictive maintenance and regulatory reporting.
Operators in petrochemical, refuelling and industrial gas applications are the primary audience for this launch.
