Product Description
1. Cryogenic Butterfly Valve is suitable for LNG, liquid nitrogen and other cryogenic media, with extended bonnet structure to reduce cold transfer outward.
2. Triple offset metal hard seal or cryogenic resilient soft seal optional.
3. Components undergo cryogenic treatment to eliminate low temperature shrinkage deformation.
4. Mainly used for shutoff, regulating and flow control in low temperature pipelines of petroleum, chemical, metallurgy, refrigeration and LNG industries.
Features & Benefits
1. Extended bonnet reduces cold loss, protecting upper packing and actuator.
2. Cryogenic stabilization treatment for components, dimensional stability under low temperature.
3. Metal hard seal or special cryogenic soft seal optional.
4. Suitable for shutoff of -196℃ cryogenic media.
5. Extended bonnet ensures distance between drip ring and packing box bottom for air heat exchange, keeping packing temperature above 0℃.
6. Stepped stem strictly calculated for rigidity to ensure actuator torque transmission.
7. Maintenance opening provided for easy inspection and maintenance.
