The tank bottom valve is an industrial device specifically designed for bottom discharge of materials from reaction vessels in clean industries such as pharmaceuticals, bioengineering, fine chemicals, and food. It is made of SUS316L stainless steel with a surface treated by mechanical or electropolishing. Its design conforms to international standards such as ISO and DIN, and offers various interface options including welding, clamping, and flanges.
This valve features a 35-degree inclined installation design, which, in conjunction with a container agitator, achieves seamless discharge and self-cleaning functions. The valve's internal mirror polishing reaches the Ra0.4um standard. Sealing components are made of materials such as PTFE, EPDM, and FPM to adapt to different media conditions, and its compact structure allows for installation in confined spaces [1-3]. The valve supports both manual and pneumatic operation. The pneumatic version can integrate a process controller and position sensor for remote automated control, and is suitable for sizes ranging from DN20 to DN80.
When using the agitator, the material at the bottom of the container rotates fully with the water flow, ensuring even mixing. The valve's 35-degree installation orientation allows for self-cleaning during material discharge, and also facilitates equipment maintenance. The valve's interior is mirror-polished with a surface roughness of 0.2-0.45μm, ensuring a cleaner valve.
