Cryogenic ball valves

Q: What materials are typically used in the construction of cryogenic ball valves?

The construction of cryogenic ball valves often involves materials specifically selected for their performance at low temperatures. Common materials include stainless steel, carbon steel, and specialized alloys designed to maintain structural integrity and resist brittleness at temperatures below -50°C. Additionally, the gaskets and seals are made from materials that can withstand extreme cold without compromising their sealing ability.

Q: How do extended bonnets enhance the performance of cryogenic ball valves?

Extended bonnets are a critical feature in cryogenic ball valves that help to keep the valve body at a safe temperature. By providing additional spacing between the valve body and the actuator, the extended bonnet minimizes heat transfer from the environment, ensuring that the internal components remain effective at low temperatures. This design is recommended for use in applications where temperatures drop below -50°C.

Q: What are the typical applications for cryogenic ball valves?

Cryogenic ball valves are widely utilized in various industries, particularly in gas production, transportation, and storage of liquefied gases such as liquid nitrogen, liquid oxygen, and natural gas. Their ability to provide low leakage rates and excellent flow characteristics makes them essential in processes requiring precise control of low-temperature fluids.

Cryogenic ball valves

Some gas treatment processes require valves able to be operated and to assure leakage rates within specified limits at low temperatures. In this case we provide a special valve design including extended bonnet (recommended for use at temperatures below minus 50°C), gaskets and seals and material selection suitable for cryogenic service.

Cryogenic ball valves are ideal where excellent full flow characteristics are required with no delay in filling time. They are widely used in gas production, transportation and storage, offering long term performance.

Our cryogenic ball valves consistently exhibit high flow capacity, tight shutoff, energy efficiency and long service life. The result is a product unmatched in reliability, stability and most importantly, safety, for use in air separation plants, LNG storage, distribution and transportation, aerospace, petrochemical and medical industries.
