The Sun Hydraulics NCFBKBV (NCFBKBV) is a needle valve with reverse flow check, designed as a fully adjustable orifice for precise flow regulation. This model allows infinite adjustment from fully closed to the maximum orifice diameter, featuring an integral high-capacity check valve that enables unrestricted flow from port 2 to port 1. While it is not pressure compensated, this needle valve is suitable for applications requiring accurate control of fluid flow. It maintains consistent performance across various conditions due to its sharp-edged orifice design, which minimizes flow variations resulting from viscosity changes. The balanced adjustment mechanism ensures ease of operation even under high-pressure scenarios. The NCFBKBV model is compatible with Sun Hydraulics' 2-port flow control cartridges, sharing the same cavity and flow path for a given frame size, although cartridge extension dimensions may differ. This valve can handle a capacity of up to 30 gpm (120 L/min) and withstands a maximum operating pressure of 5000 psi (350 bar). Leakage is minimal at 0.7 cc/min under specified conditions. The valve features an adjustment range of 5-5 counterclockwise turns from fully closed to open, with specific torque requirements for installation and adjustment components. Constructed with Sun\u2019s floating style design, the NCFBKBV minimizes potential binding issues caused by excessive installation torque or machining variations in the cavity/cartridge interface. The model weighs approximately 1.30 lbs (0.60 kg) and requires a Viton seal kit for maintenance and optimal performance.
