Cryogenic Gate Valve
Introduction
The Cryogenic Gate Valve is a type of shut-off valve used for connecting or isolating media in pipelines. It’s specially designed to handle cryogenic media such as methane, liquid natural gas, alkene, carbon dioxide, liquid ammonia, liquid oxygen, liquid nitrogen, and liquid hydrogen. This valve is appropriate for medium and large diameter pipelines and has a body made of high-grade ductile black cast iron which reduces its weight by approximately 20%-30% compared to conventional gate valves. The valve’s flat bottom design minimizes debris accumulation and allows for smooth fluid flow. The gate plate is made of high-quality rubber, ensuring precise geometry and firmly attached to the ductile cast gate plate, providing good elastic memory and preventing detachment.

Applications
Cryogenic gate valves are an essential component in a variety of industries. In the aerospace sector, these valves are used to fuel rockets and satellites, allowing them to travel to space. In the medical equipment industry, cryogenic gate valves are used for storing and transporting biological samples and vaccines, ensuring that they are kept at the correct temperature. Cryogenic gate valves are also utilized in the energy sector for liquefied natural gas (LNG) production and transportation, where they play a critical role in ensuring the safety and efficiency of the process. Furthermore, in the food and beverage industry, these valves are used for freezing and chilling food products, maintaining their quality and freshness.
In addition to their use in these industries, cryogenic gate valves are also essential in laboratory applications. They are commonly used for handling liquid helium and other cryogenic fluids, which require precise temperature control to prevent contamination and ensure accurate measurements. Cryogenic gate valves play a crucial role in maintaining the integrity of experiments and ensuring reliable results.
