Needle Metering Valve
Kirkco uses Needle Metering Valves for processing low to high viscosity medias.
Example: Positive Displacement Needle Metering Valve
The valve consists of two separate parts, a fluid section and a pneumatic section. This separation reduces the chance for leaking material to flow into the actuating air cylinder that might cause a malfunction of the valve. The needle is sealed by means of adjustable packing set. Speed of metering depends on the material viscosity and the material pressure.
