The Sun Hydraulics NFCDHFN (Material Number: NFCDHFN) is a versatile needle valve designed for precise flow regulation in hydraulic systems. This fully adjustable orifice can be fine-tuned from fully closed to the maximum orifice diameter, allowing it to function effectively as a flow control or shutoff valve. The NFCDHFN is not pressure compensated, meaning that the flow rate through the valve is proportional to the square root of the pressure differential between ports 1 and 2. This model features a balanced adjustment mechanism for easy handling, even under high-pressure conditions. Its sharp-edged orifice design minimizes variations in flow due to changes in fluid viscosity, ensuring consistent performance. The valve's bidirectional flow path allows for flexible installation, although the preferred direction is from port 1 to port 2 to maintain interchangeability with other flow controls. When fully closed, the adjustment mechanism ensures zero leakage, enhancing system reliability. The NFCDHFN cartridge is interchangeable with other 2-port flow control cartridges of the same frame size but may differ in extension dimensions from the mounting surface. This model operates efficiently at a maximum capacity of 20 gpm (80 L/min) and can withstand pressures up to 5000 psi (350 bar). It requires an installation torque of 30-35 lbf ft (41-47 Nm) and features an internal hex size adjustment screw of 5/32 inches (4 mm). The locknut hex size is 9/16 inches (15 mm), with a recommended torque of 80-90 lbf in (9-10 Nm). Weighing just .30 lb (0.15 kg), this needle valve is compact yet robust. For systems utilizing phosphate ester fluids, cartridges configured with EPDM seals are available; however, they should not be exposed to petroleum-based fluids as this will damage the seals.

Needle valves are fully adjustable orifices used to regulate flow. They are infinitely adjustable from fully closed up to the maximum orifice diameter. They are not pressure compensated and may be used as flow controls or as shutoff valves.
- 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.
- The flow path through this valve is bi-directional. The preferred path is port 1 to 2, to allow interchangeability with other flow controls.
- There is no leakage when the adjustment mechanism is turned to the shut-off position.
- 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.
