Cryogenic Globe Control Valve – Series 1100c

Cryogenic Globe Control Valve

Series 1100c

Dembla Cryogenic Globe Control Valves are designed & manufactured to exceed the highest industry standards. These Cryogenic Valves are designed to provide control of liquid and gases where cryogenic temperature may reach up to -196°C. When required, these valves can reliably provide tight shut-off for special applications. The optimized geometry of the these valve bodies presents smooth curves and a flow passageway nearly constant, which reduce the flowing fluid turbulence and increase the valve flow rate capacity. These valves are available in a range of configurations meeting various specifications and can deliver excellent performance.

Features


Height of the extended bonnet suitably designed to keep away stuffing box from cryogenic surfaces. This avoids the failure of seals due to low temperature effect.

Right selections & testing of materials are basics for good performance of cryogenic valves. This is done meticulously for low temperature service suitable for -196°C.

Varieties of trim options are available to match the different process applications.
