The Sun Hydraulics NFDCKAV (NFDCKAV) is a precision-engineered needle valve designed to provide fully adjustable flow regulation. This valve offers infinite adjustability from fully closed to the maximum orifice diameter and serves as both a flow control device and a shutoff valve. It is important to note that this needle valve is not pressure compensated, meaning the fixed orifice size regulates flow proportionally to the square root of the pressure differential between ports 1 and 2. The bidirectional flow path allows for flexibility in installation, with the preferred direction being port 1 to 2 for interchangeability with other flow controls. The NFDCKAV model features a balanced adjustment mechanism that ensures ease of use even under high-pressure conditions, up to a maximum operating pressure of 5000 psi (350 bar). The sharp-edged orifice design helps minimize variations in flow due to changes in fluid viscosity. With no leakage when fully closed, this model ensures reliable performance in critical applications. This cartridge valve is physically and functionally interchangeable with other 2-port flow control cartridges of the same frame size, although extension dimensions from the mounting surface may vary. It accommodates an adjustment range of up to 5.5 counterclockwise turns from fully closed to open. The NFDCKAV has specific installation requirements, including a valve hex size of 1-1/8 inches (28.6 mm) and an installation torque range of 45-50 lbf ft (61-68 Nm). Additionally, this model is compatible with EPDM seals for systems using phosphate ester fluids but should not be exposed to petroleum-based fluids as they can damage the seals. The cartridge's compact design has a weight of .60 lb (.30 kg), making it suitable for various hydraulic applications where precision flow control is essential.

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.
