Cryogenic Triple Offset Butterfly Valves
Series - 7600
Dembla Triple Offset Cryogenic Butterfly Valves are designed & manufactured for tight shut off and throttling service. This reduces wear and tear on the sealing and extends its service life. The bonnet is extended to ensure that the gland area remains free from freezing even for temperature down to -196°C. By adopting the most advanced design concept, high precision processing control and excellent process management, the low temperature cryogenic butterfly valves have many outstanding advantages, such as reliable sealing, high stability at low temperature and long service life.
