Product Description:

Applied to low temperature and cryogenic application, such as: LNG, Air Separation, Ethylene Quickly Quenching Cracking Gas,
Ethylene Rectifying, Low Temperature Methanol Cleaning Process.

Performance Features:

1.Extension Bonnet Structure: assure the stuffing box sealing performance, prevent frost on stuffing box
2.Automatic Pressure Relief Seat: avoid cavity pressure abnormal rising
3.-196°C liquid nitrogen cryogenic treatment: turn the remaining austenite into martensite, prevent component dimensional change
from organization phase transformation caused by temperature change.
4.Nitrogen Test Leakage: assure valve sealing performance, ensure valve is applicable to wide range of application.
