The Sun Hydraulics NFBCKCE (Material Number: NFBCKCE) is a versatile needle valve designed for precise flow regulation in hydraulic systems. This fully adjustable orifice can be set anywhere from fully closed to the maximum orifice diameter, allowing it to function as both a flow control and a shutoff valve. The valve is not pressure compensated, meaning that the flow rate is regulated in proportion to the square root of the pressure differential across ports 1 and 2. It features a balanced adjustment mechanism for easy handling even under high pressures, and its sharp-edged orifice design minimizes variations in flow due to changes in fluid viscosity. The bidirectional flow path offers flexibility, with port 1 to 2 being the preferred path for interchangeability with other flow controls. This model incorporates Sun's floating style construction, which helps prevent internal parts from binding due to excessive installation torque or machining variations. With no leakage when fully closed, it ensures reliable operation. The NFBCKCE is compatible with systems using phosphate ester fluids when configured with EPDM seals; however, exposure to petroleum-based fluids can damage these seals. This needle valve fits into a T-162A cavity and operates at a maximum pressure of 5000 psi (350 bar). It has an adjustment range of five counterclockwise turns from fully closed to open and features various hex sizes for installation and adjustment: a valve hex size of 3/4 inch (19.1 mm), an internal hex size of 5/32 inch (4 mm) for the adjustment screw, and a locknut hex size of 9/16 inch (15 mm). The model weighs 0.20 lb (0.10 kg) and includes Viton seal kits as part of its configuration options.

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.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
