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.
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
