LNG Carrier Valves: A Chinese-built 174,000 m³ Ship Delivers With a Full Range of Domestic Cryogenic Valves
A 174,000 m³ LNG carrier delivered five months early is the first Chinese-built ship to carry a full range of domestically made cryogenic valves in its cargo containment system.
Lead
A 174,000 m³ LNG carrier named Puteri Johor was delivered at Changxing Island, Shanghai, on 29 May 2026, five months ahead of schedule, according to China News Network and the China Securities Journal.
The ship is reported as the first Chinese-built LNG carrier whose cargo containment system core is fitted with a full range of domestically made cryogenic valves.
Facts
The ship. Length overall 299 m, beam 46.4 m, depth 26.25 m, four cargo tanks, 174,000 m³ of LNG. It is to run on the Malaysia–China route. (Source: China News Network, 2026-05-29.)
The valve point. A large LNG carrier uses more than a thousand cryogenic valves, across cargo loading and unloading, re-liquefaction and dual-fuel supply lines. The cargo containment system has to hold the cargo at −163 °C (−261 °F). The reported breakthrough is that the range of cryogenic valve types on the cargo system is now fully domestic.

What the builder states about testing. The valves were developed by the builder and, in sea trials, passed extreme-low-temperature, pressure-fluctuation and ship-motion testing, with sealing, response and operating performance reported as excellent and commissioning completed with zero defects.

The supply-chain statement. China News Network quotes the designer as describing the result as full coverage of the nine cryogenic valve families used on an LNG carrier, in actual shipboard installation. (Source: China News Network, 2026-05-29.)
Note on scope. Shipboard cryogenic valves are not among the five general valve types this site screens, and −163 °C (−261 °F) sits below the temperature at which this site hands every cryogenic enquiry to a person. This item is recorded for the cryogenic content, not as a recommendation.

Note on sourcing. Both items originate as press reports of a ship delivery, one of them citing the builder and its designer. We report the stated facts — what was delivered, what the valves cover, and what testing was described — and we do not repeat performance claims beyond those stated or rank suppliers.
What the source does not state
The reports do not state which manufacturer built the valves, the valve types and sizes in the nine families, the design pressure or temperature of individual valves, the number of valves supplied, or the standards the valves were tested against.
