1/2'' to 4'' Stainless Steel AISI 316L Aseptic Tri Clamp Tank Bottom Sanitary Valve
Sanitary diaphragm valve are made from stainless steel SS316, and come with double gaskets: EPDM and PTFE. The sanitary design allows precise control of the fluid flow rate with low turbulence and minimal back pressure.Tank bottom valve, with its conical profile allows for complete drainability and the prevention of deadlegs or entrapment areas. These valves are installed by either bolting or welding to the tank surface. Our tank bottom valves are available in sizes ranging from 1/4” through 4”, are manufactured using type SA-479 316L stainless steel and are available with a wide variety of drain ports and end connections. Positive closure can be achieved by means of manual or pneumatic actuation.
Spezilla offers many surface finish option to meet your specifications. In addition, heat number are etched into the body providing full traceability with mill test summaries provided.
