The revolutionary design of JH Cryogenic Side-Mounted Ball Valves is reflected in their ease of maintenance: the side-mounted maintenance structure, through a precise side opening design, allows for quick assembly and disassembly of internal components while maintaining the integrity of the pressure boundary; the extra-long bonnet design effectively isolates cryogenic conduction, ensuring the stuffing box remains within its operating temperature range; the bidirectional metal-sealed system uses special cryogenic materials to maintain seal integrity in ultra-low temperature environments down to -196°C; and overpressure protection of the cavity automatically releases excess pressure generated by medium vaporization through a built-in pressure relief mechanism. This innovative structure makes side-mounted cryogenic ball valves the preferred solution for maintaining sensitive cryogenic systems.
Meeting the special control requirements of side-mounted valves, providing precise low-temperature control, and offering a dedicated drive solution for low-temperature valves.

FAQ-Cryogenic Side-Mounted Ball Valves
The Cryogenic Side-Mounted Ball Valve (also known as a top-entry ball valve) is characterized by a removable installation cover on the side of the valve body. This design allows internal components such as the ball, seats, and seals to be installed, inspected, and maintained directly from the side of the valve body without needing to remove the entire valve from the pipeline system. This greatly simplifies maintenance procedures, reducing maintenance costs and downtime.
Their main advantages are superior maintainability and long service life. When an ordinary one-piece ball valve develops internal leakage or is damaged, it requires complete removal from the pipeline for repair, which is time-consuming and labor-intensive. In contrast, the internal components of a Side-Mounted Ball Valve can be quickly replaced or serviced inline, making it particularly suitable for critical cryogenic pipelines requiring high reliability and easy maintenance.
They are highly suitable for the following applications requiring high reliability and ease of maintenance:
Key process lines in LNG receiving terminals and liquefaction plants
Liquid oxygen and liquid nitrogen pipelines in air separation units
Applications requiring regular seal inspection or preventive maintenance
Installation locations with compact space but where future maintenance convenience must be ensured
To ensure accurate selection, please provide:
Medium and Operating Temperature: Specific medium composition and temperature range (e.g., -196°C)
압력 등급: Design pressure and operating pressure
Valve Size and Connection Type: (e.g., RF flange, butt weld)
Body and Trim Material requirements
Whether an Extended Stem is needed to accommodate insulation thickness
We ensure its sealing reliability through multiple design features:
Metal-to-Metal Body Seal: A precision-machined flange between the installation cover and the valve body, combined with high-strength bolts and gaskets, ensures absolute reliability of the primary seal at low temperatures
Advanced Seat Sealing: Uses deep-cryogenic treated reinforced PTFE or metal elastic sealing rings that contract uniformly at low temperatures, ensuring bubble-tight sealing
Stringent Factory Testing: Every valve undergoes rigorous testing, including cryogenic tests, to verify its sealing performance under working conditions
