The Cryogenic Globe(Stop) valve is applicable to the management system of low-temperature liquid storage and transportation equipment. It has the characteristics of flexible switching and reliable sealing. It can also be used for other low-temperature and cryogenic medium management systems. The Cryogenic Globe(Stop) valve generally refers to a stop valve with a working temperature lower than – 110 ℃, which is widely used in liquefied natural gas, liquefied petroleum gas, and other low-temperature industries. At present, it can manufacture a Cryogenic Globe(Stop) valve with an applicable temperature of – 196 ℃. All parts are pretreated with liquid nitrogen to completely avoid sealing deformation and leakage during use

Design Features

The structure is simpler than the gate valve, and the manufacturing and maintenance are more convenient.

The sealing surface is not easy to wear and scratch, with good sealing performance. There is no relative sliding between the valve disc and the sealing surface of the valve body during opening and closing, so the wear and scratch are not serious, with good sealing performance and long service life.

During opening and closing, the valve disc stroke is small, so the height of the stop valve is smaller than that of the gate valve, but the structure length is longer than that of the gate valve.

The opening and closing torque is large and the opening and closing is laborious. The opening and closing time is the principal.

The fluid resistance is large. Because the medium channel in the valve body is tortuous, the fluid resistance is large and the power consumption is large
