The Sun Hydraulics NCGBKEV (NCGBKEV) is a needle valve with a reverse flow check, designed as a fully adjustable orifice to regulate flow. This model is infinitely adjustable from fully closed to the maximum orifice diameter, allowing for precise control over fluid dynamics within hydraulic systems. An integral high-capacity check valve ensures unrestricted flow from port 2 to port 1, though it is important to note that this valve is not pressure compensated. The design of this cartridge allows it to be physically and functionally interchangeable with other 2-port flow control cartridges, maintaining the same flow path and cavity for a given frame size, although extension dimensions may vary. The NCGBKEV features a balanced adjustment mechanism that facilitates easy adjustments even at high pressures. Its sharp-edged orifice design minimizes variations in flow due to viscosity changes, making it suitable for various fluid conditions. Cartridges equipped with EPDM seals are compatible with systems using phosphate ester fluids; however, these seals can be damaged by petroleum-based fluids and lubricants. The floating style construction of the cartridge minimizes the risk of internal parts binding due to excessive installation torque or machining variations. Key specifications include a cavity type of T-18A Series 4 with a capacity of 60 gpm (240 L/min), and a maximum operating pressure of 5000 psi (350 bar). The valve has an installation torque range between 350 - 375 lbf ft (474 - 508 Nm) and an adjustment screw internal hex size of 5/32 in (4 mm). The locknut requires a torque between 80 - 90 lbf in (9 - 10 Nm), and the model weighs approximately 3.00 lb (1.35 kg). This product is ideal for applications requiring precise flow regulation without pressure compensation in hydraulic systems.
