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