The Sun Hydraulics NFECLFE (Material Number: NFECLFE) is a versatile needle valve designed for precise flow regulation in hydraulic systems. This fully adjustable orifice allows for infinite adjustment from fully closed to the maximum orifice diameter, offering flexibility in controlling fluid flow. Despite not being pressure compensated, it can effectively function as both a flow control and a shutoff valve. The NFECLFE model is part of the 2-port flow control cartridge series, ensuring physical and functional interchangeability with other cartridges of the same frame size, although extension dimensions may vary. The valve operates by regulating flow proportionally to the square root of the pressure differential across ports 1 and 2 due to its noncompensating nature. A balanced adjustment mechanism facilitates easy adjustments even under high pressures, while the sharp-edged orifice design minimizes variations in flow due to changes in fluid viscosity. This model supports bidirectional flow, with a preferred path from port 1 to port 2 to maintain interchangeability with other controls. When turned to the shutoff position, the valve ensures zero leakage. The NFECLFE model is compatible with systems using phosphate ester fluids when equipped with EPDM seals; however, exposure to petroleum-based fluids may damage these seals. It features a cavity T-16A series 3 design with a capacity of up to 30 gpm (120 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). The valve requires specific installation torque settings and includes details such as hex sizes for various components and recommended locknut torque ranges. Weighing approximately 1.30 lb (0.60 kg), this needle valve is engineered for robust performance in demanding hydraulic applications.

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.
