The Sun Hydraulics NCEBKEN (Material Number: NCEBKEN) is a needle valve with a reverse flow check, designed to be fully adjustable for precise flow regulation. It allows for infinite adjustments from fully closed to the maximum orifice diameter, making it versatile for various applications. The valve features an integral high-capacity check valve that ensures unrestricted flow from port 2 to port 1. Notably, this model is not pressure compensated, which means the fixed orifice size regulates flow in proportion to the square root of the pressure differential across ports 1 and 2. The balanced adjustment mechanism offers ease of adjustment even under high pressures, while the sharp-edged orifice design minimizes flow variations due to changes in fluid viscosity. This cartridge is part of a series where all 2-port flow control cartridges are interchangeable concerning flow path and cavity dimensions, though extension dimensions may vary. Configured with EPDM seals, it is suitable for use with phosphate ester fluids but should be kept away from petroleum-based fluids to prevent seal damage. The Sun floating style construction reduces risks of internal binding due to excessive torque or machining variations. Key specifications include a T-5A cavity series with a capacity of 12 gpm (45 L/min) and a maximum operating pressure of 5000 psi (350 bar). It has minimal leakage at specified conditions and features several adjustment and installation specifications such as a valve hex size of 1-1/8 inches and an installation torque range between 45-50 lbf ft (61-68 Nm). The model weighs approximately 0.40 lb (0.20 kg) and uses Viton seal kits for maintenance purposes.
