The Sun Hydraulics NFECKEN (Material Number: NFECKEN) is a versatile needle valve designed for precise flow regulation in hydraulic systems. It features a fully adjustable orifice that allows for infinite adjustments from fully closed to the maximum orifice diameter, making it suitable for use as both a flow control and a shutoff valve. Despite not being pressure compensated, this valve effectively regulates flow in proportion to the square root of the pressure differential across its ports. The sharp-edged orifice design minimizes variations in flow due to changes in fluid viscosity, ensuring consistent performance. The balanced adjustment mechanism provides ease of operation even under high-pressure conditions, with no leakage when set to the shutoff position. This 2-port flow control cartridge is physically and functionally interchangeable with others of the same frame size, although extension dimensions may vary. Its bidirectional flow path prefers port 1 to 2 for compatibility with other flow controls. Designed for maximum operating pressures up to 5000 psi (350 bar) and a capacity of 30 gpm (120 L/min), it is suitable for demanding applications. The valve's installation requires a torque of 150-160 lbf ft (203-217 Nm), and it features an internal hex size adjustment screw and locknut hex size for secure settings. Configured with EPDM seals, this model is intended for use with phosphate ester fluids but should not be exposed to petroleum-based fluids as they can damage the seals. Weighing approximately 1.30 lb (0.60 kg), it offers reliable performance in various hydraulic applications requiring precise flow control without leakage risks when fully closed.

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.
