Needle metering valves are used for the processing of low to high viscosity media. The valve consists of two separate parts. This means that it is not possible for any leaking material to enter the actuating air cylinder, which could cause a malfunction. The needle is sealed by means of an adjustable packing set (Metering volume: 0.001 - 3.0 cm3).
