The Sun Hydraulics NFFCKHN (Material Number: NFFCKHN) is a versatile needle valve designed for precise flow regulation in hydraulic systems. This fully adjustable orifice valve allows for infinite adjustments from fully closed to the maximum orifice diameter, making it ideal for applications requiring precise control over fluid flow. The valve is not pressure compensated and can function as either a flow control or shutoff valve. It features a balanced adjustment mechanism that facilitates easy adjustments even under high pressures, while the sharp-edged orifice design minimizes flow variations due to changes in fluid viscosity. The NFFCKHN is part of Sun Hydraulics' 2-port flow control cartridge series, which are interchangeable with other cartridges of the same frame size, offering consistent flow paths and cavity dimensions. However, extension dimensions from the mounting surface may vary. The valve supports bidirectional flow with a preferred path from port 1 to port 2 to maintain interchangeability with other flow controls. This model operates at a maximum capacity of 60 gpm (240 L/min) and can withstand pressures up to 5000 psi (350 bar). It features an adjustment range of up to 55 counterclockwise turns from fully closed to fully open and ensures no leakage when in the shutoff position. The NFFCKHN comes equipped with EPDM seals suitable for systems using phosphate ester fluids but should not be exposed to petroleum-based fluids, greases, or lubricants as they may damage the seals. The valve's installation requires specific torques: a valve installation torque of 350-375 lbf ft (474-508 Nm), an adjustment screw internal hex size of 5/32 inches (4 mm), and a locknut torque range of 80-90 lbf in (9-10 Nm). With a model weight of 3.00 lb (1.35 kg), this needle valve offers reliable 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.
