Manual ball valves for food and beverage meet applicable NSF (National Sanitation Foundation) or 3-A requirements for handling or contact with food, personal care, or dairy products. Manual valves open and close with a handle, which visually indicates whether the valve is open or closed depending on the handle's position relative to the valve body. Two-way valves have one inlet port and one outlet port. Three-way have multiple inlet and outlet ports configured in different flow patterns (e.g., Y, T, or L) for mixing, splitting, or directing media flow.
