The Sun Hydraulics NCGBYEN (NCGBYEN) 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, providing versatility in flow regulation applications. It features an integral high-capacity check valve that allows unrestricted flow from port 2 to port 1. Notably, these valves are not pressure compensated, meaning the fixed orifice size will regulate flow based on the square root of the pressure differential across ports 1 and 2. The balanced adjustment mechanism ensures ease of adjustment even under high pressures, and its sharp-edged orifice design minimizes flow variations due to viscosity changes. This cartridge is interchangeable with all other 2-port flow control cartridges of the same frame size, though cartridge extension dimensions may vary from the mounting surface. The NCGBYEN model incorporates Sun's floating style construction, which minimizes internal part binding caused by excessive installation torque or cavity-cartridge machining variations. It is configured for systems using phosphate ester fluids when equipped with EPDM seals; however, exposure to petroleum-based fluids can damage these seals. The cartridge fits into a T-18A cavity and has a capacity of 60 gpm (240 L/min) with a maximum operating pressure of 5000 psi (350 bar). It has minimal leakage at specified conditions and provides up to 5.5 counterclockwise turns for full adjustment from closed to open positions. The valve hex size is 1-5/8 inches, with an installation torque requirement between 350 and 375 lbf-ft. The model weighs approximately 3 pounds and comes with specific seal kit options for maintenance needs.

Needle valves with reverse-flow check are fully adjustable orifices used to regulate flow. They are infinitely adjustable from fully closed up to the maximum orifice diameter. An integral high-capacity check valve provides unrestricted flow from port 2 to port 1. They are not pressure compensated.
- All 2-port flow control cartridges are physically and functionally interchangeable (i.e. same flow path, same cavity for a given frame size). However, cartridge extension dimensions from the mounting surface may vary.
- Because needle valves are non-compensating devices, the fixed orifice size will regulate flow through the valve in proportion to the square root of the pressure differential across ports 1 and 2.
- A balanced adjustment mechanism allows for easy adjustment even at high pressures.
- The sharp-edged orifice design minimizes flow variations due to viscosity changes.
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
