Sun Hydraulics Needle Valve - Fully Adjustable - NFBCLCN

Features
 • 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
