Stainless Steel DN80 ISO LPG Tank Flush Bottom valve
 
TheStainless Steel DN80 ISO LPG Tank Flush Bottom valve  is a discharge valve specifically designed for clean industries such as food, pharmaceuticals, and bioengineering.It adopts a Y-shaped flow channel and a quick-install structure at the tank bottom, eliminating sanitary dead corners and material residue. It can be automatically opened and closed by a pneumatic actuator. It is mainly installed at the bottom of containers such as reactors, storage tanks, and fermenters for material discharge, filtration, and diversion. It meets international sanitary standards such as GMP, FDA, and 3A and is compatible with CIP/SIP cleaning and sterilization processes.
 
Stainless Steel DN80 ISO LPG tank valveachieves thorough and residue-free discharge with its angled, dead-angle-free flow channel, superior to the dead-angle deposition of ball valves.Compared to the discharge valve shown below, pneumatic + intelligent feedback improves automation efficiency and is more convenient to operate than the lower-discharge valve.Compared to shut-off discharge valves, it has lower flow resistance and faster discharge speed. Compared to the discharge valve shown above, the valve core does not extend into the tank, resulting in higher cleanliness.
 
TheStainless Steel DN80 ISO LPG tank bottom valve mainly consists of a Y-type valve body, valve core assembly, pneumatic actuator, intelligent control module, and quick-connect tank bottom connector. The valve body adopts a Y-shaped oblique flow channel design and is installed at the bottom of the container, allowing materials to be discharged naturally under gravity without residue. The pneumatic actuator drives the valve core to rise and fall using compressed air, realizing the opening and closing of the valve. The intelligent control module can provide real-time feedback on the valve position status and supports remote control and automated linkage. The quick-connect tank bottom connector allows the valve to be quickly connected to the bottom of the container, with no leakage or residue after installation, meeting sanitary cleaning and sterilization requirements.
