Product Overview
The low-temperature three-way ball valve is a high-performance fluid control valve. It is specially designed for low-temperature conditions. This valve plays an important role in the industrial field. It provides a reliable solution for the transmission and distribution of low-temperature media.
Materials
- Valve Body and Ball
– Typically made of stainless steel, such as 304 or 316. These materials offer good low-temperature toughness and corrosion resistance.
– Low-temperature alloy steels, like 9% nickel steel, are also used. They maintain high strength and good toughness at extremely low temperatures.
- Sealing Materials
– Uses polytetrafluoroethylene (PTFE), metal seals, or reinforced graphite. These materials excel in low temperatures.
– They maintain good elasticity and sealing performance even at low temperatures, effectively preventing medium leakage.
- Valve Stem
– Usually made of stainless steel. It undergoes special low-temperature treatment.
– This ensures strength and wear resistance in low-temperature environments.
Structure
- Three-Way Design
– Achieves medium diversion, confluence, and flow direction switching. This meets complex pipeline layout requirements.
– The internal flow channel is optimized to reduce fluid resistance and improve flow efficiency.
- Extended Stem Structure
– Features a long neck structure to reduce heat loss of low-temperature media at the valve cover.
– This design prevents the medium from freezing at the valve cover and seal failure.
- Anti-Static and Fire-Proof Design
– Equipped with anti-static devices to eliminate static electricity during operation.
– Includes a fire-proof structure. It maintains sealing performance for a certain period during a fire to ensure safety.
Operating Conditions
- Liquefied Natural Gas (LNG) Industry
– Used in LNG receiving stations, storage tanks, and transmission pipelines.
– Controls the flow direction and distribution of natural gas. It operates stably at temperatures as low as -162℃, ensuring safe LNG storage and transportation.
- Air Separation Equipment
– Used in air separation units to control the flow of cryogenic media, such as liquid oxygen, liquid nitrogen, and liquid argon.
– Adapts to low temperature and high purity media, ensuring precise control of the separation process.
- Petrochemicals
– Used in the low-temperature storage and transportation of chemical raw materials like ethylene and propylene.
– Regulates and cuts off the medium. It works reliably under complex process conditions and low temperatures.
- Refrigeration Industry
– Controls the flow direction and flow of refrigerants in large cold storage and refrigeration systems.
– Achieves precise temperature control.
In short, the low-temperature three-way ball valve is essential in many low-temperature fields. It features high-quality materials, a reasonable structural design, and adaptability to low-temperature conditions. It provides a strong guarantee for the safe and efficient operation of industrial production.
