The Sun Hydraulics NCECLBV (NCECLBV) is a needle valve with a reverse-flow check, designed to offer precise flow regulation through an adjustable orifice. This model allows for infinite adjustability from fully closed to the maximum orifice diameter, ensuring tailored flow control in various applications. It features an integral high-capacity check valve that provides unrestricted flow from port 2 to port 1, although it is not pressure compensated. The NCECLBV's design ensures compatibility across all 2-port flow control cartridges, maintaining the same flow path and cavity for a given frame size, though cartridge extension dimensions may vary. Its non-compensating nature means that the fixed orifice size regulates flow proportionally to the square root of the pressure differential across ports 1 and 2. The balanced adjustment mechanism facilitates easy adjustments even under high pressure, while the sharp-edged orifice design reduces flow variations due to viscosity changes. Sun's floating style construction minimizes internal binding risks due to excessive installation torque or cavity-cartridge machining variations. The NCECLBV has a cavity T-5A series with a capacity of 3 gpm (11 L/min) and can operate at a maximum pressure of 5000 psi (350 bar). It exhibits minimal leakage at maximum valve leakage rates of 5 drops/min (0.3 cc/min) at 110 SUS (24 cSt). The adjustment range spans up to 5.5 counterclockwise turns from fully closed to fully open position, with specific torque requirements for installation and adjustments detailed in its specifications. This model weighs approximately .40 lb (.20 kg) and utilizes Viton seals for optimal performance in hydraulic systems.
