Engineered for Extreme Low-Temperature Reliability
The Kunjian Cryogenic Ball Valve is a high-performance flow control solution designed specifically for the rigorous demands of the LNG, aerospace, and industrial gas sectors. Built to operate flawlessly at temperatures as low as -196°C (-321°F), this valve ensures maximum safety and zero-leakage performance in the most volatile environments.
Key Features & Benefits:
- Constructed from high-grade stainless steel (CF8M/CF3M) and specialized alloys that maintain structural toughness and prevent brittle failure at cryogenic temperatures.
- Features a standard extended stem to keep the packing area away from the cold medium, preventing frost build-up and ensuring the stem seal remains functional.
- Integrated pressure relief design prevents abnormal pressure spikes in the valve cavity caused by the expansion of trapped liquefied gases.
- Precision-machined internals and advanced seat materials (PCTFE/Kel-F) ensure smooth operation even under extreme thermal shock.
- Manufactured and tested in accordance with international standards including API 6D, BS 6364, and ISO 17292 to meet global procurement requirements.
Industrial Applications:
- Liquefaction plants, receiving terminals, and transport tankers.
- Production of liquid oxygen, nitrogen, and argon.
- Handling of liquid rocket propellants.
- Specialized low-temperature chemical reactions.
