Tank Bottom Ball Valve Intec K521

Description of Tank Bottom Ball Valve Intec K521

Minimal Dead Leg: Flush mount tank valves are typically welded to the lowest part of the tank; allowing the tank to be fully drained. Flush mount tank valves can also be welded to tank covers or welded to the tank wall. The valve is welded tightly to the tank, and the “dead space” is kept to a minimum.

Optional End Connection for 3-piece Ball Valves.
Material: 316L Stainless Steel. Low Carbon 316 Stainless Steel decreases the possibility of reducing corrosion resistance by welding.
Machined from 316L Stainless Steel; eliminates porosity.

Tank bottom valves for tank, vessel, and reactor applications.

Polyethers, produced by alkaline catalysis can be mixed with acid for work-up. The corresponding salt is then formed in a neutralization reaction. When aqueous acids are used, crystallization is induced by the subsequent removal of the water in order to separate the salt formed in the final processing step.

The salt is then filled into Big Packs. For this purpose, the metal-seated tank bottom ball valve of nominal size DN300/200 and pressure rating PN10 with a stem extension and a pneumatic rotary actuator is used. The tank bottom ball valve from the System technology modular system is almost sump-free due to the angled stem and the resulting optimized space requirement facilitates installation under the reactor/boiler.

Since the salt tends to stick or bake on metallic surfaces, the ball was equipped with a metallic stripping edge and a connection for leakage monitoring and flushing was realized in the dead space.
