The Sun Hydraulics NFCCOIV (Material Number: NFCCOIV) is a versatile needle valve designed for precise flow regulation in hydraulic systems. This fully adjustable orifice valve allows users to control flow from fully closed to the maximum orifice diameter, making it ideal for use as a flow control or shutoff valve. The NFCCOIV model is not pressure compensated, meaning that the flow through the valve is regulated in proportion to the square root of the pressure differential across its ports. It features a balanced adjustment mechanism that ensures easy operation even under high-pressure conditions and a sharp-edged orifice design that minimizes variations due to changes in fluid viscosity. The bidirectional flow path of this valve, with a preferred direction from port 1 to port 2, ensures compatibility with other flow control devices. When set to the shutoff position, there is no leakage, providing reliable performance in critical applications. The NFCCOIV model can handle a maximum operating pressure of 5000 psi (350 bar) and supports a capacity of up to 7 gpm (28 L/min). It requires an installation torque between 30 and 35 lbf ft (41 and 47 Nm), with an internal adjustment screw hex size of 5/32 inches (4 mm) and a locknut hex size of 9/16 inches (15 mm). The valve's compact design weighs just .30 lb (.15 kg), making it suitable for various system configurations. Cartridges configured with EPDM seals are specifically designed for systems using phosphate ester fluids; however, exposure to petroleum-based fluids will damage these seals. For those requiring corrosion resistance, Sun Hydraulics offers zinc-nickel plating options. Overall, the NFCCOIV needle valve provides reliable and precise flow control solutions for demanding hydraulic applications.

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.
