제품 설명

Cryogenic side entry ball valve is suitable for working conditions with temperature up to -196℃ and is widely used in liquefied natural gas, liquefied petroleum gas, air separation and other cryogenic industries. In production, we apply international advanced technology and adopt LIP SEAL sealing ring to keep the valve with excellent sealing performance in application. At the same time, this series of valves can realize online maintenance.

Performance Features

Key designs and technologies in cryogenic side entry ball valve:
● Lip-seal + packing double seal of valve stem can reduce the amount of packing.
● Finite element assisted design is used to obtain the optimal wall thickness of the extended valve cover to ensure the best cooling effect.
● The arc moon groove design of the extended valve cover increases the cooling area and enhances the cooling effect.
● The drip plate design increases the cooling area and prevents the packing from freezing; effectively prevents condensed water from dripping onto the valve body.
● Lip-seal + gasket double seal is set at the body cover connection to prevent leakage.
● The valve seat adopts DIB-2 structure, which can ensure that the pressure in the middle cavity is stably released to the specified side when the pressure exceeds the limit.
● The valve seat seal is a Lip-sea structure, which has both the elastic compensation of the spring and the low-temperature elastic sealing performance of PTFE, ensuring excellent sealing effect at low temperatures.
● The valve seat sealing surface is imported CTFE, which still has good elasticity at ultra-low temperatures to ensure that the seal does not fail.
● The extended bonnet and long handle structure design ensures better coaxiality of the ball handle, valve stem and bonnet, and more sensitive switching.
● All fasteners in contact with low temperatures are fully threaded.
● The surface of the ball is hardened to ensure that it will not be scratched at low temperatures.
