Low-temperature valves
Thread Content
With a design temperature of -30 to -40°C, is it more cost-effective to use ordinary valves made of LCB material or specialized low-temperature valves? Also, I’m concerned that standard LCB valves may not have undergone impact testing upon leaving the factory
For design temperatures ranging from -30 to -40°C, it is recommended to use specialized low-temperature valves. Although LCB material valves can generally withstand low-temperature environments, if they have not undergone impact testing at the time of manufacture, they may pose safety risks under extreme low-temperature conditions. Although specialized low-temperature valves may be more expensive, in the long run, considering safety and durability, they offer better value for money. .
-Valves made of normal WCB can withstand temperatures of 30–40°C. Moreover, the actual temperature generally does not reach the designed temperature. Therefore, ordinary valves at room temperature can be used.
