The Sun Hydraulics NFDCOAV (NFDCOAV) is a needle valve designed for precise flow regulation in hydraulic systems. This valve features a fully adjustable orifice that allows for infinite adjustment from fully closed to the maximum orifice diameter, making it versatile for use as either a flow control or shutoff valve. It is important to note that this valve is not pressure compensated, meaning the flow regulation is dependent on the pressure differential across its ports. The NFDCOAV model offers bidirectional flow capability, with the preferred path being from port 1 to port 2 to ensure interchangeability with other flow controls. This particular needle valve includes a balanced adjustment mechanism, which facilitates easy adjustments even under high-pressure conditions. Additionally, its sharp-edged orifice design helps minimize variations in flow due to changes in fluid viscosity. The NFDCOAV model ensures no leakage when the adjustment mechanism is turned to the shutoff position, providing reliable performance in applications requiring complete closure. The cartridge is configured with EPDM seals, making it suitable for systems utilizing phosphate ester fluids; however, exposure to petroleum-based fluids can damage these seals. It fits into a T5A cavity and boasts a capacity of 12 gpm (45 L/min) with a maximum operating pressure of 5000 psi (350 bar). The valve's physical specifications include a hex size of 1-1/8 inches and an installation torque range of 45-50 lbf-ft. The internal hex size for adjustment is 5/32 inches, while the locknut hex size measures 9/16 inches, requiring a torque of 80-90 lbf-in for secure installation. With its robust design and precision control capabilities, the Sun Hydraulics NFDCOAV needle valve is an essential component for optimizing hydraulic system performance.

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.
