The Sun Hydraulics NFCDHFV (Material Number: NFCDHFV) is a precision needle valve designed to regulate flow through fully adjustable orifices. It allows infinite adjustment from fully closed to the maximum orifice diameter but is not pressure compensated. This model can function as either a flow control or shutoff valve. It features bidirectional flow capability, with the preferred direction being port 1 to 2 for compatibility with other flow controls. The valve's sharp-edged orifice design minimizes variations in flow due to changes in fluid viscosity, and its balanced adjustment mechanism ensures easy operation even under high pressure conditions. The NFCDHFV can handle a maximum operating pressure of 5000 psi (350 bar) and has a capacity of 20 gpm (80 L/min). The valve requires an installation torque of 30-35 lbf ft (41-47 Nm) and features an internal hex size of 5/32 in (4 mm) for the adjustment screw, with a locknut hex size of 9/16 in (15 mm). It includes EPDM seals suitable for systems using phosphate ester fluids; however, these seals are not compatible with petroleum-based fluids. The valve weighs approximately 0.30 lb (0.15 kg) and uses Viton seal kits for maintenance purposes. This needle valve is part of Sun Hydraulics' Series 1 cartridges, known for their physical and functional interchangeability across similar frames and cavities, though extension dimensions may vary from the mounting surface.

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.
