Temperature by material
The temperature limit follows the material grade, so the range above spans every grade offered rather than any one build. Confirmed at quotation.
- Alloy Steel
- -29°C to 120°C
- Low Temperature Steel
- -46°C to 120°C
- Stainless Steel
- -196°C to 120°C (cryogenic service requires an extended bonnet and a BS 6364 type test)
Operating media
Typical applications
- LNG process systems: flow regulation and system pressure control
- Chemical process systems: refrigerant liquid nitrogen transport
- Air separation plants
- Food processing: liquid food delivery systems
Features
- Deep cold treatment process applied to body materials for reliable performance at -196°C
- Lateral (side) maintenance port allows replacement of sealing components without removing valve from line
- Double eccentric butterfly plate geometry
- Extended valve stem with anti-heat-bridge design to prevent cold energy conduction into actuator
- Long service life under ultra-low temperature conditions
Description
A double eccentric butterfly valve designed for cryogenic service with operating temperatures down to -196°C, using special stainless steel or low-temperature alloy valve bodies subjected to deep cold treatment. Features a lateral maintenance port allowing sealing component replacement without removing the valve from the pipeline. Equipped with an extended valve stem and anti-heat-bridge design to prevent cold energy conduction.
Selection notes
This cryogenic butterfly valve is a double eccentric butterfly valve and metal seated butterfly valve pattern.
Sizes run DN150 to DN2000, in PN10, PN16, PN25, PN40.
The body is offered in Low Temperature Steel, Stainless Steel and Alloy Steel, so the grade can be matched to the service rather than the other way round.
Stated service media include liquefied natural gas (lng), liquid nitrogen, refrigerants and liquid food.
It is catalogued for Oil & Gas.
Working temperature is -196°C to 120°C, by material.
Built to Complies with international standards (unspecified).
