The Sun Hydraulics NCEBOBN (Material Number: NCEBOBN) is a needle valve with a reverse flow check, designed to provide adjustable flow regulation. This component features an infinitely adjustable orifice from fully closed to its maximum diameter, allowing precise control over fluid flow. It incorporates an integral high-capacity check valve that ensures unrestricted flow from port 2 to port 1. However, it is important to note that this valve is not pressure compensated, meaning the flow regulation is proportional to the square root of the pressure differential across ports 1 and 2. The design includes a balanced adjustment mechanism for easy operation even at high pressures and a sharp-edged orifice that minimizes variations due to changes in fluid viscosity. The NCEBOBN model is physically and functionally interchangeable with other 2-port flow control cartridges of the same frame size, although extension dimensions may vary. It features Sun's floating style construction, which reduces the likelihood of internal binding due to installation torque or machining variations. The cartridge has a capacity of 12 gpm (45 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). It has minimal leakage at standard viscosity levels and comes with specific hex sizes for adjustments and installation torque requirements. This model can be configured with EPDM seals for compatibility with phosphate ester fluids, though exposure to petroleum-based substances should be avoided as it may damage the seals. The product weighs approximately 0.40 lb (0.20 kg) and requires specific torque settings for optimal installation and operation.
