The Sun Hydraulics NCEBKEV (NCEBKEV) is a versatile needle valve with a reverse flow check, designed to provide precise flow regulation in hydraulic systems. This fully adjustable orifice allows for infinite adjustment from fully closed to the maximum orifice diameter, making it ideal for applications requiring accurate flow control. The valve features an integral high-capacity check valve that ensures unrestricted flow from port 2 to port 1. It is important to note that this needle valve is not pressure compensated, meaning the fixed orifice size will regulate flow in proportion to the square root of the pressure differential across ports 1 and 2. The NCEBKEV model incorporates a balanced adjustment mechanism, facilitating easy adjustments even under high-pressure conditions. Its sharp-edged orifice design minimizes variations in flow due to changes in fluid viscosity. Additionally, this cartridge employs Sun's floating style construction, which reduces the risk of internal parts binding caused by excessive installation torque or machining variations. This cartridge is physically and functionally interchangeable with other 2-port flow control cartridges of the same frame size but may have different extension dimensions from the mounting surface. The NCEBKEV model supports a cavity T-5A, Series 2, with a capacity of up to 12 gpm (45 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). The valve has minimal leakage at specified conditions and supports EPDM seals for use with phosphate ester fluids while avoiding petroleum-based fluids. For installation and maintenance, it features specific torque requirements: Valve Installation Torque ranges between 45 - 50 lbf ft (61 - 68 Nm), and Locknut Torque is between 80 - 90 lbf in (9 - 10 Nm). With its robust build and precise control capabilities, this needle valve serves as an essential component for hydraulic systems requiring reliable flow management.
