The Sun Hydraulics NFECLEN (Material Number: NFECLEN) is a needle valve designed to provide precise flow regulation through its fully adjustable orifice. This valve is not pressure compensated, making it suitable for use as a flow control or shutoff valve in hydraulic systems. The NFECLEN model features a bidirectional flow path, with the preferred direction being from port 1 to port 2 to ensure compatibility with other flow control devices. With a maximum operating pressure of 5000 psi (350 bar) and a capacity of 30 gpm (120 L/min.), this valve is robust enough for demanding applications. The design includes a balanced adjustment mechanism that facilitates easy adjustments even under high pressures, and the sharp-edged orifice minimizes flow variations caused by changes in fluid viscosity. The valve's adjustment range spans up to 5.5 counterclockwise turns from fully closed to fully open, providing fine-tuning capabilities for various operational needs. It has no leakage when fully closed, ensuring reliable performance as a shutoff valve. Constructed for use in systems with phosphate ester fluids, the NFECLEN model is configured with EPDM seals that must be protected from petroleum-based fluids which can cause damage. The installation requires specific torque settings: 150-160 lbf ft (203-217 Nm) for the valve and 80-90 lbf in (9-10 Nm) for the locknut. With its compact design featuring a hex size of 1-1/4 inches and an internal hex size of 5/32 inches for adjustment, this needle valve offers both versatility and precision in 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.
