Fully adjustable needle valve Capacity: .19 in. (4,8 mm) Functional Group: Products : Cartridges : Flow Control : 2 Port : Fully Adjustable Needle Valve Model: NFCC-KDN Product Description Needle valves are fully adjustable orifices used to regulate flow. They are infinitely adjustable from fully closed up to the maximum orifice diameter. They are not pressure-compensated. They may be used as flow controls or as shutoff valves. Technical Features All 2-port flow control cartridges are physically and functionally interchangeable (i.e. same flow path, same cavity for a given frame size). However, cartridge extension dimensions from the mounting surface may vary. The sharp-edged orifice design minimizes flow variations due to viscosity changes. Because needle valves are non-compensating devices, the fixed orifice size will regulate flow through the valve in proportion to the square root of the pressure differential across ports 1 and 2. The flow path through this valve is bi-directional. The preferred path is
