Stainless Steel FDA Food Grade Manual Conical Tank Bottom Valve

The working principle of the stainless steel sanitary manual tank bottom valve is to use a low-torque manual drive mechanism to drive the conical valve core up and down through a precision-machined valve stem to achieve precise fluid discharge. Its unique self-draining design can avoid residue at the bottom of the tank and prevent fluid retention from causing microbial growth. The special angle seal ensures no leakage when closed, while reducing fluid impact when opened, and avoiding foam or turbulence affecting product quality. Using a stainless steel sanitary manual tank bottom valve can achieve precise discharge, avoid microbial contamination caused by fluid retention, reduce cleaning difficulty, and improve production efficiency.

Cleaning function: CIP/SIP compatible, removable cleaning interface

• The stainless steel sanitary manual tank bottom valve core adopts a special angle cone design to ensure no residual liquid, reduce cross contamination, and meet CIP/SIP cleaning requirements.
• The stainless steel sanitary manual tank bottom valve adopts a seamless one-piece casting process, without welding points, to enhance pressure resistance, prevent bacterial growth, and improve the hygiene level.
• The tank bottom flow channel of the stainless steel sanitary manual tank bottom valve is optimized at a special angle to reduce dead angles and improve discharge efficiency.
• The stainless steel sanitary manual tank bottom valve adopts a mechanical limit design to prevent damage to the sealing ring due to excessive rotation, improve operational safety and service life.
• The inner wall of the stainless steel sanitary manual tank bottom valve body is finely polished to ≤0.4μm, reducing fluid residue and adhesion, and improving cleanliness and hygiene level.
• The stainless steel sanitary manual tank bottom valve has a reserved sensor installation interface, which can be connected to pressure, temperature or liquid level sensors to achieve intelligent monitoring and remote control.

Stainless steel sanitary manual tank bottom valves are widely used in the following industries: Food and beverage industry: control the bottom discharge of storage tanks such as milk, juice, and beverages. Dairy industry: used for liquid discharge from the bottom of pasteurization tanks, fermentation tanks, etc. Pharmaceutical industry: used for liquid storage tanks to ensure aseptic discharge in accordance with GMP standards. Biotechnology industry: control the outflow of biological preparations such as vaccines and culture fluids from the bottom of tanks. Cosmetics industry: control the bottom discharge of storage tanks such as creams, essences, and perfumes. Drinking water treatment industry: used for pure water and ultrafiltration water tank bottom discharge and cleaning.
