The Sun Hydraulics NCGBHEN (NCGBHEN) is a needle valve with a reverse flow check, designed to provide precise flow regulation in hydraulic systems. This valve features an infinitely adjustable orifice, allowing for seamless control from fully closed to the maximum orifice diameter. It incorporates an integral high-capacity check valve that ensures unrestricted flow from port 2 to port 1, although it is not pressure compensated. The NCGBHEN model is part of the 2-port flow control cartridge series, which are physically and functionally interchangeable within the same frame size, though cartridge extension dimensions may vary. The balanced adjustment mechanism facilitates easy adjustments even under high-pressure conditions. Its sharp-edged orifice design minimizes flow variations due to viscosity changes, enhancing performance stability. This model is configured with EPDM seals specifically for use in systems utilizing phosphate ester fluids; exposure to petroleum-based fluids will damage these seals. The valve employs Sun's floating style construction to reduce the risk of internal parts binding due to excessive installation torque or machining variations. It fits into a T-18A cavity and belongs to Series 4 with a capacity of 60 gpm (240 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). The valve has minimal leakage at standard viscosity levels, with a maximum leakage rate of 10 drops/min (0.7 cc/min). The adjustment range spans up to 5.5 counterclockwise turns from fully closed to fully open, and the valve requires specific installation torques for optimal performance. Weighing approximately 3 lbs (1.35 kg), this model offers efficient flow control capabilities for various hydraulic applications requiring precise fluid management.

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.
