Features：
(patent no. :ZL 2004 20025919.8)
1) Sequential shut-off method is adopted to make the double ball valve release without flow media into the sea (this function is especially important for highly toxic and highly corrosive media).
2) An automatic mechanical pressure relief device is set at the top ball valve of the emergency release device, which automatically opens when the double ball valves disconnect, eliminating the hammering effect immediately and ensuring that the loading arm will not be out of balance.
3) The double soft seal and metal seal are adopted to gain time and reduce loss for the separation of the ship from the jetty in the occasion of fire.
4) A booster device is set on the push rod mechanism of the emergency release device, which will automatically pop up when the hydraulic push rod is opened to ensure 100% disconnection.
