A sanitary control valve also called a sanitary or food-grade valve, made of durable 316L stainless steel, is used to adjust the flow of liquids or gases in clean systems like food and beverage production. It has a body, an internal seat that controls flow, an actuator that moves to adjust the opening, a spring for force, and a knob for manual adjustments. When you turn the knob, it changes the spring's tension, moving the actuator and the seat to regulate flow and keep the process clean and safe. This valve is crucial in industries where hygiene is vital and regular cleaning is necessary like food, drinks, dairy, and beer-making, where cleanliness is key and frequent washing is needed.
