Tankboden-Membranventil
This sanitary tank bottom diaphragm valve is specially designed for direct mounting at the bottom of process tanks, providing reliable and hygienic shut-off or sampling control. It features a full drainable body design to eliminate dead zones, ensuring complete emptying of the tank and preventing media residue. Constructed from high-grade stainless steel with food-grade diaphragm seals, it meets the strict hygiene requirements of food, beverage, pharmaceutical and biotech industries.

Hauptmerkmale
• The tank bottom diaphragm valve (also referred to as a vessel outlet valve or drain valve) is specifically designed for installation at the lowest point of process vessels, tanks, fermenters, and bioreactors.
• Its primary function is to enable complete, hygienic, and sterile drainage of process fluids without leaving residual product in the vessel.
• The valve features a short-bottom connection with minimal dead leg, compliant with the Institute of Brewing (IOB) and EHEDG guidelines for vessel drainage.
• The short-bottom nozzle extends slightly into the vessel, creating a flush internal profile that prevents product accumulation at the tank bottom.
• This valve is an indispensable component in pharmaceutical bioreactors, food processing vessels, brewing tanks, and dairy storage silos where complete product recovery, sterile drainage, and cleanability are paramount.
