Performance Features

● With precision machining technology, the gap between the valve stem and the extended valve cover is strictly quality tested and controlled below 1mm, ensuring smooth rotation of the valve stem and reducing the possibility of freezing and damage of the valve stem under low temperature conditions.
● Lip seal (Elgiloy+PTFE): This seal can combine the flexible compensation function of the spring and the excellent sealing performance of PTFE, maintain excellent sealing performance in low temperature environments, and has a fireproof design through graphite secondary sealing.
● All fasteners are low-temperature full-threaded structures to avoid deformation and sealing failure of fasteners due to long-term use.
