Cryogenic Globe Valve-Globe valve series-截止阀厂家-上海冠环阀门制造有限公司

Product description

The ultra-low temperature shut-off valve is suitable for low temperature working conditions of -196 ℃. Adopting advanced design concepts, high-precision processing control, and rigorous process management, strictly controlling various production processes, the SRIT ultra-low temperature valve has outstanding advantages such as reliable sealing, low operating torque, high low-temperature stability, and long service life. The product is widely used in liquefied natural gas, liquefied petroleum gas, air separation, and other low-temperature industries.

Features

1. All parts of the cryogenic globe valve in contact with the medium are treated at low temperature to ensure that the valve can be used safely in a variety of different low-temperature media.
2. According to the temperature of the medium on site, the valve (minus 46 °C ~ -101 °C) can be selected with a short shaft globe valve, and the long shaft globe valve (-101 °C ~ 254 °C) is selected.
