The Sun Hydraulics NFEDKHN (Material Number: NFEDKHN) is a highly versatile needle valve designed for precise flow regulation in hydraulic systems. This product features a fully adjustable orifice, allowing for infinite adjustments from fully closed to the maximum orifice diameter, making it suitable for both flow control and shutoff applications. It is important to note that this valve is not pressure compensated, meaning the fixed orifice size regulates flow proportionally to the square root of the pressure differential between ports 1 and 2. This noncompensating nature allows for bidirectional flow, with the preferred path being port 1 to port 2 to ensure interchangeability with other flow controls. The NFEDKHN model includes a balanced adjustment mechanism that facilitates easy adjustments even under high-pressure conditions. Its sharp-edged orifice design minimizes variations in flow due to changes in fluid viscosity. The valve ensures zero leakage when in the shutoff position, providing reliable performance across various applications. This model has a cavity T-16A series 3 design with a capacity of up to 90 gpm (340 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). It features an adjustment range of up to 5.5 counterclockwise turns from fully closed to fully open. Installation requires a valve hex size of 1-1/4 inches (31.8 mm) and torque specifications ranging from 150-160 lbf.ft (203-217 Nm). The internal hex size for the adjustment screw is 5/32 inches (4 mm), while the locknut hex size measures at 9/16 inches (15 mm) with a torque requirement of 80-90 lbf.in (9-10 Nm). Weighing approximately 1.30 lb (0.60 kg), this needle valve comes equipped with Viton seals as part of its cartridge seal kit, ensuring compatibility with various hydraulic fluids except those based on petroleum products which may damage EPDM seals used in some configurations.

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.
