The Sun Hydraulics NFCDLFV (Material Number: NFCDLFV) is a versatile needle valve designed for precise flow regulation in hydraulic systems. This fully adjustable orifice valve allows for infinite adjustment from fully closed to the maximum orifice diameter, making it suitable for applications requiring meticulous flow control or complete shutoff. While not pressure compensated, it can effectively manage flow based on the square root of the pressure differential across ports 1 and 2. The NFCDLFV features a balanced adjustment mechanism, ensuring easy operation even under high pressures, and a sharp-edged orifice design to minimize flow variations due to changes in fluid viscosity. The valve supports bidirectional flow with a preferred path from port 1 to 2, allowing for seamless interchangeability with other control valves. It guarantees zero leakage when fully closed. This Series 1 cartridge fits into a T-13A cavity and offers a capacity of up to 20 gpm (80 L/min) with a maximum operating pressure of 5000 psi (350 bar). The adjustment mechanism enables up to 5.5 counterclockwise turns from fully closed to open, providing precise control over the flow rate. Installation requires a valve hex size of 7/8 inch (22.2 mm) and an installation torque between 30-35 lbf ft (41-47 Nm). The adjustment screw has an internal hex size of 5/32 inch (4 mm), while the locknut requires a hex size of 9/16 inch (15 mm) and torque between 80-90 lbf in (9-10 Nm). Weighing just .30 lb (.15 kg), this needle valve is compact yet robust, making it an excellent choice for demanding hydraulic applications where space and weight are considerations. The valve can be configured with EPDM seals for compatibility with phosphate ester fluids, but these seals should not be exposed to petroleum-based substances.

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.
