The Sun Hydraulics NCFBKCN (NCFBKCN) is a needle valve with a reverse flow check, designed for precise flow regulation. This valve features an adjustable orifice that allows for infinite adjustment from fully closed to the maximum orifice diameter, making it suitable for applications requiring fine control of fluid flow. It includes an integral high-capacity check valve that enables unrestricted flow from port 2 to port 1, though it is important to note that the valve is not pressure compensated. This means the fixed orifice size will regulate flow in proportion to the square root of the pressure differential across ports 1 and 2. This model is part of Sun's 2-port flow control cartridges, which are physically and functionally interchangeable within the same frame size, although extension dimensions can vary. The design incorporates a balanced adjustment mechanism for easy adjustments even at high pressures and uses a sharp-edged orifice to minimize variations due to viscosity changes. The floating style construction helps prevent internal parts from binding due to excessive installation torque or machining variations. The NCFBKCN has a cavity type of T-16A Series 3 with a capacity of up to 30 gpm (120 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). It has minimal leakage at specified conditions and features user-friendly adjustment options including a counterclockwise turn mechanism and various hex sizes for installation and adjustment. The valve's construction ensures durability and reliability in demanding environments, with additional resources available for design integration and enhanced corrosion resistance options.
