The Sun Hydraulics NFDCYBN (Material Number: NFDCYBN) is a versatile needle valve designed for precise flow regulation in hydraulic systems. This fully adjustable orifice allows for smooth and infinite adjustments from completely closed to the maximum orifice diameter, providing effective flow control or acting as a shutoff valve. Although not pressure compensated, it maintains functionality across various applications due to its balanced adjustment mechanism, which facilitates easy operation even under high-pressure conditions. The NFDCYBN's sharp-edged orifice reduces flow variations caused by changes in fluid viscosity, ensuring consistent performance. This bidirectional valve features a preferred flow path from port 1 to port 2, promoting interchangeability with other flow control devices. It guarantees zero leakage when fully closed, enhancing system reliability and efficiency. Built with EPDM seals, it is suitable for use in systems utilizing phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based substances. The NFDCYBN model fits the Cavity T-5A and has a capacity of 12 gpm (45 L/min) with a maximum operating pressure of 5000 psi (350 bar). It requires an installation torque of 45-50 lbf ft (61-68 Nm) and features an adjustment screw internal hex size of 5/32 in. (4 mm). Weighing just .60 lb (.30 kg), this needle valve is compact yet robust. Additionally, it can be configured with Viton seal kits for enhanced durability in specific environments.

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.
