Cryogenic Gate Valves, Globe Valves, and Check Valves are designed for service with low-temperature media below -29℃. These are typically categorized into three temperature ranges:-29℃ to -46℃ (or -50℃)-46℃ (or -50℃) to -101℃ (or -110℃)-101℃ (or -110℃) to -196℃Applications below -196℃ are extremely rare and generally limited to media such as liquid hydrogen or liquid helium. MECCO has conducted targeted research in this area and successfully developed prototype valves for such conditions.Cryogenic valves are designed and manufactured in accordance with BS 6364, ISO 28921-1, MSS SP-134, SPE 77-200, GB/T 24925, and other applicable standards. Available pressure ratings include CL150, CL300, CL600, CL800, CL900, CL1500, and CL2500 (or PN16 to PN420).For cryogenic gate valves rated CL600 and below, MECCO provides integral bonnet forging dies up to NPS16, and for globe valves up to NPS12. Bonnet extensions meet the height requirements specified in SPE 77-200. For valve sizes beyond this range, if welding of extended bonnets is not permitted or if special height requirements are specified by the customer, custom die design solutions can be offered.

Cryogenic Ball Valves are designed for low-temperature service below -29℃ and are generally categorized into three temperature ranges: -29℃ to -46℃ (or -50℃); -46℃ (or -50℃) to -101℃ (or -110℃); -101℃ (or -110℃) to -196℃. Applications below -196℃ are extremely rare and typically involve media such as liquid hydrogen or liquid helium. For service at -196℃ and above, the valves are designed and manufactured in accordance with BS 6364, ISO 28921-1, MSS SP-134, SPE 77-200, GB/T 24925, and other applicable standards. Pressure ratings include CL150, CL300, CL600, CL900, CL1500, and CL2500 (or PN16 to PN420). Bonnet extension height is designed to comply with the requirements of SPE 77-200, and customized designs can be provided if customers have specific height requirements.

Cryogenic Butterfly Valves are suitable for low-temperature media below -29℃ and are generally classified into three temperature ranges: -29℃ to -46℃ (or -50℃); -46℃ (or -50℃) to -101℃ (or -110℃); -101℃ (or -110℃) to -196℃. Applications below -196℃ are extremely rare and typically involve media such as liquid hydrogen or liquid helium. For service at -196℃ and above, the valves are designed and manufactured in accordance with BS 6364, ISO 28921-1, MSS SP-134, SPE 77-200, GB/T 24925, and other applicable standards. Pressure ratings include CL150, CL300, and CL600 (or PN16 to PN110). Bonnet extension height is designed according to the requirements of SPE 77-200, and customized designs can be provided if customers have special requirements for extension height.
