In high temperature and high pressure conditions, the import side of the damper is designed to pressure in the cavity pressure relief means to prevent the temperature change caused by abnormal increase of the phenomenon, to ensure safety.
Fully sealed structure, good protective performance, all-weather use.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, diameter, drive, etc.. Specific please contact or online advisory contact.
