Ribel Valvole’s cryogenic ball valves have been selected for the Rio Grande LNG project in Texas, one of the most important liquefied natural gas (LNG) plants currently under development in the United States. This prestigious and highly technical supply confirms its commitment to the design and manufacturing of cryogenic valves for extreme environments, fully compliant with the most demanding international standards.
Specifically, Ribel supplied two models of cryogenic ball valves: The C1 model, a compact unidirectional wafer valve with 100 mm cryogenic stem extension, ideal for installations in tight spaces. The C4 model, a three-piece inline serviceable valve, designed for applications requiring frequent maintenance or sanitization between process batches.
Both models have been tested according to API 607 8th Ed., ISO 10497:2022, and BS6364, and are engineered to ensure reliable performance from –196 °C to +200 °C. They are made of ASTM A182 F316/316L stainless steel, with R-PTFE (TFM) seats and combined PTFE, graphite, and silicone sealing systems. All valves feature anti-blowout stems and double external sealing, essential for safe operation in critical service.
The supply of cryogenic valves for the HRV Residual Gas Compressor system was made possible through its long-standing partnership with Fluidomatic, the trusted commercial and technical partner. Fluidomatic handled customer coordination, ensuring that the valves were correctly integrated into a complex and highly engineered system.
