Parker Hannifin’s Instrumentation Products Division Europe (IPDE) has launched a new range of Cryogenic Proportional Relief Valves aimed at improving the efficiency and safety of hydrogen storage and other cryogenic gas systems.
The valves are designed to protect storage tanks and other group 1 gas systems from overpressure events by releasing gas gradually rather than in a single burst. According to Parker, this controlled release helps manage boil-off gas, reduce media loss, and lower operational costs over time.
The components use Parker’s balanced bellow design, which maintains consistent performance under varying back pressures. The company said its stem sealing technology enables “snag-free” opening and smooth reseating, improving reliability and system uptime.
Each valve is factory-set with an accuracy of ±3%, ensuring stable operation within defined pressure limits. The valves are PED-approved and come with Parker’s A-LOK and CPI tube connections for quicker, leak-free installation. Mounting holes for brackets also allow for flexible system integration.
“Our Cryogenic Proportional Relief Valves are engineered to deliver maximum value to our customers,” said Jacob Hawkins, Innovation Manager at Parker IPDE. “In an industry where safety and reliability are critical, our valves ensure consistent operation and peace of mind, enhancing our customers’ operational efficiency.”
