The Sun Hydraulics NCFBHAN (NCFBHAN) is a needle valve with a reverse-flow check, designed as a fully adjustable orifice to regulate flow. This product is infinitely adjustable from fully closed to the maximum orifice diameter and features an integral high-capacity check valve that allows unrestricted flow from port 2 to port 1. The valve is not pressure compensated, meaning the fixed orifice size regulates flow in proportion to the square root of the pressure differential across ports 1 and 2. This model incorporates a balanced adjustment mechanism for easy adjustments even under high pressures and utilizes a sharp-edged orifice design to minimize flow variations due to viscosity changes. Additionally, it features Sun's floating style construction, which reduces the risk of internal parts binding from excessive installation torque or machining variations in cavity-cartridge interfaces. The NCFBHAN model fits into a T-16A cavity of Series 3 with a capacity of up to 30 gpm (120 L/min) and can handle a maximum operating pressure of 5000 psi (350 bar). The maximum valve leakage at 110 SUS (24 cSt) is limited to 10 drops/min (0.7 cc/min). The adjustment mechanism allows for up to five counterclockwise turns from fully closed to fully open, ensuring precise flow control. Installation requires specific torque values: valve installation torque ranges between 150 - 160 lbf ft (203 - 217 Nm), while the locknut torque is set between 80 - 90 lbf in (9 - 10 Nm). With its robust design and reliable performance parameters, this needle valve is suitable for applications demanding precise flow regulation without compromising on durability or ease of use.
