The needle-off dispensing valve is a type of dispensing valve used in liquid dispensing systems. It is designed to stop the flow of liquid immediately after the valve is closed, which prevents dripping or spilling of the liquid from the needle tip. This is achieved by retracting the needle into the valve body, creating a seal that prevents any remaining liquid from dripping out.
Needle off dispensing valve use anodized aluminum alloy as the main material, strong corrosion resistance. Can connect all kinds of needles.
