Filter valve is a type of valve that is specifically designed to regulate the flow of fluids or gases through a filtration system. These valves are commonly used in industrial or commercial settings where the quality of the fluid or gas being filtered is critical. The filter valve works by controlling the flow of the fluid or gas through the filtration system, allowing only clean and filtered material to pass through while blocking any impurities or contaminants. This helps to maintain the purity and quality of the end product, as well as prolonging the lifespan of the filtration system itself.
