Tank bottom valve is used for emptying material inside container and preventing remains in valve chamber. With valve seat open inside container design, it's avoid valve unexpected open caused by excessive pressure of pipeline. Tank bottom valve has 45 degrees and 90 degree two designs, operated by manual or pneumatic.

Design and features - Sanitary design according to 3A. - Complete drainage system to prevent the retention. - Normally closed valve (closed by spring) -standard version. - Normally open valve (opened by spring) by simple turning pneumatic actuator. - The valve seat opens tank inside to avoid accidental openings. - 360oC adjustable body, even after welding flange to tank. - Open lantern for visual inspection of the shaft sealing. - Easy disassembly by loosening the clamp. - Connections: clamp and flange
