Cryogenic Valve Manufacturers in USA Accord

Valvesonly are the top Cryogenic Valve Manufacturers in USA. They are designed to regulate the flow of fluids at extremely low temperatures, typically below -150°C (-238°F). These valves are used in a wide range of  industries such as aerospace, medical, and liquefied natural gas (LNG) processing, where handling cryogenic liquids like liquid nitrogen and liquid oxygen play an important role in fluid control systems. Cryogenic valves regulate the flow rate, pressure, and direction of extremely cold fluids in a system, ensuring a secure seal to prevent leaks and maintain operational safety.

They are constructed using materials that  withstand extreme cold temperature and designed with features to mitigate thermal contraction, cryogenic valves incorporate unique sealing mechanisms and insulation to operate effectively in cryogenic environments. They feature extended bonnets to protect internal components and stem seals from the extreme cold temperature.

How do cryogenic valves work?

Cryogenic valves are specially designed to function at extremely low temperatures, often below -150°C (-238°F). The valve controls the flow of cryogenic fluids such as liquid nitrogen, liquid oxygen, or liquefied natural gas. They have the ability to maintain a tight seal and operate reliably in such harsh conditions. They are constructed from materials that can withstand thermal contraction and have extended bonnets that protect the stem seals from the cryogenic temperatures, ensuring that the operating mechanism remains functional.

The valves often incorporate special features like low emission stem packing and precision-machined seats to prevent leakage.

Types:

Cryogenic Ball Valve

Cryogenic Check Valve

Cryogenic Gate Valve

Cryogenic Long Stem Globe Valve

Why cryogenic valves have long stem?

They  often have long stems mainly to maintain the integrity of the stem seal in extremely low-temperature environments. When a valve is exposed to cryogenic temperatures, the metal parts, including the stem, contract due to thermal shrinkage. This contraction can cause the stem seal, which is located near the valve body, to lose its effectiveness if it is also exposed to the extreme cold.

By extending the length of the stem, the seal is positioned further away from the coldest part of the valve, which is typically near the valve body. This design helps to keep the stem seal at a relatively higher temperature, reducing the risk of it becoming brittle or losing its ability to maintain a tight seal. The extended length of cryogenic valve stems serves as a safeguard to maintain the sealing mechanism's performance and dependability in very cold conditions.
