Product description
The cryogenic globe valve is mainly used in the pipeline of the cryogenic liquid medium under zero (-46 °C ~ -196 °C ~ 254 °C), as the connection and switch cut-off of the medium. The body of the globe valve and the fittings in contact with the medium are treated with special low temperature. The flow channel is designed to be low in and high out, and the handwheel is rotated clockwise to make the sealing packing of the valve stem spool and the flow channel mouth tightly sealed and closed for closed cut-off. The handwheel rotates counterclockwise, the valve stem, the spool rises, and the medium flow is open when it leaves the flow channel.
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.
