The Sun Hydraulics NFFCHHV (NFFCHHV) is a versatile needle valve designed for precise flow regulation in hydraulic systems. It operates as a fully adjustable orifice, allowing for infinite adjustments from fully closed to the maximum orifice diameter. This valve is not pressure compensated, making it suitable for use as a flow control or shutoff valve. It features a balanced adjustment mechanism that facilitates easy adjustments even at high pressures and a sharp-edged orifice design that minimizes flow variations due to viscosity changes. The NFFCHHV model supports bidirectional flow, with the preferred path being from port 1 to 2, ensuring interchangeability with other flow controls. This needle valve is part of the Cavity T-18A Series 4 and has a capacity of 60 gallons per minute (240 liters per minute) with a maximum operating pressure of 5000 psi (350 bar). The valve's adjustment can be made through 5.5 counterclockwise turns from fully closed to fully open. The hex size for installation is 1-5/8 inches (41.3 mm), and the recommended installation torque ranges between 350 and 375 lbf-ft (474 to 508 Nm). Additionally, the adjustment screw requires an internal hex size of 5/32 inches (4 mm), and the locknut has a hex size of 9/16 inches (15 mm) with a torque specification of 80 to 90 lbf-in (9 to 10 Nm). Weighing in at approximately 3 pounds (1.35 kg), this model also offers configurations with EPDM seals suitable for systems utilizing phosphate ester fluids, while avoiding exposure to petroleum-based fluids which may damage the seals.

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.
