The Sun Hydraulics NCEBKDV (NCEBKDV) is a needle valve with a reverse flow check, designed as a fully adjustable orifice to regulate flow. It is capable of infinite adjustment from fully closed to its maximum orifice diameter. This model features an integral high-capacity check valve that allows unrestricted flow from port 2 to port 1, although it is not pressure compensated. The NCEBKDV is physically and functionally interchangeable with other 2-port flow control cartridges of the same frame size, meaning they share the same flow path and cavity. However, the cartridge extension dimensions may vary from the mounting surface. As a non-compensating device, this needle valve regulates flow in proportion to the square root of the pressure differential across ports 1 and 2 due to its fixed orifice size. The design includes a balanced adjustment mechanism for easy adjustment even under high pressures. Its sharp-edged orifice minimizes flow variations attributed to changes in viscosity. Cartridges with EPDM seals are intended for systems using phosphate ester fluids, as exposure to petroleum-based fluids can damage these seals. The Sun floating style construction helps prevent internal part binding due to excessive installation torque or machining variations in the cavity-cartridge interface. The NCEBKDV has a capacity of 12 gpm (45 L/min) and can operate at pressures up to 5000 psi (350 bar). It features minimal valve leakage at specified conditions and offers ease of installation with specified torque settings for its components.
