Cryogenic valves are capable of withstanding extremely low temperatures and functioning as intended. They are used in different industries, including the oil and gas and aerospace sectors, where it is necessary to handle fluids at lower temperatures. Although each industry has its own definition of a cryogenic temperature, it is usual to see cryogenic valves work between -40°F (-40°C) to -320°F (-195.5°C). Further:
Lightweight valves are preferable for cryogenic applications because they are quicker to cool from ambient to cryogenic temperatures.
Lighter cryogenic valves often have lower conductivities than heavier bodies, which helps to limit heat inflow.
Cryogenic media require several types of cryogenic valves. Each kind has unique properties that make it ideal for some purposes but not others.
Cryogenic gate valves use a wedge-type gate as the obturator, which moves closer to the mating body seat. They offer good flow properties, like ball valves, but are limited by wear and tear.
These valves, as named because of their spherical form, include a moving disc called the obturator that spins at a 90-degree angle to the plane of the coordinated body seat. These cryogenic valves provide improved long-term sealing performance stability but are moisture-prone and ineffective in applications where the flow rate is critical.
Cryogenic check valves from XINTAI, such as double disc or swing check valves, are made for flow requirements in process industries. A check valve is a valve that typically only permits fluid to flow in one way through it. Most check valves lack valve handles because they typically function automatically without operators or control.
These valves typically have a low temp sustainable body seat and a ball acting as the obturator. They are more prone to wear and tear along their seals and the ball itself, but they offer superior flow characteristics than globe valves. They are most useful in applications where a free flow channel is required.
XINTAI produces valves based on BS 6364, MSS SP-134, ISO 21011, ISO 10497, ASME B16.34 standards. Some of these standards are briefed here:
The MSS SP-134 is the most often used code in North America. It specifies the criteria for cryogenic valves with body/bonnet extensions in terms of design, material, dimensions, manufacturing, non-destructive and pressure testing.
This British Standard defines the criteria for the design, production, and testing of cryogenic valves.
This international standard specifies the criteria for the cryogenic fluid valves’ design, production, and inspection.

We are a prestigious the Cryogenic valve manufacturer from China.XINTAI is registered with the following governmental agencies:
Cryogenic valves for industrial uses are available in a range of sizes and pressure classes. Sizes typically vary from 1/8 inch to 88 inches (3 mm to 2240 mm). Cryogenic valves have pressure ratings ranging from ultra-high vacuum conditions to 700 bar.
Typical cryogenic valves include specifically constructed globe, gate, ball, and butterfly valves. As a result, selecting the appropriate type of cryogenic valve for the application is critical. In cryogenic service, there are no stringent criteria regarding valve type. However, there is a preference for quarter-turn ball valves and triple offset butterfly valves
The fundamental issue with cryogenic valves is that any fluid leaking into the atmosphere via gaskets or gland seals degrades the valve and connected component functioning. Furthermore, such leaking at the valve stem will generate localized ice, which may cause the valve-operating mechanism to seize.
Cryogenic valves are used in low-temperature applications (-195 to -40 °C) in the following areas:
