The Sun Hydraulics NCGCHBV (NCGCHBV) is a precision-engineered needle valve with a reverse-flow check, designed for precise flow regulation in hydraulic systems. This valve offers infinite adjustability from fully closed to its maximum orifice diameter, allowing for tailored flow control. It features an integral high-capacity check valve that ensures unrestricted flow from port 2 to port 1, though it is important to note that this model is not pressure compensated. The NCGCHBV is part of Sun Hydraulics' series of 2-port flow control cartridges, which are interchangeable in terms of flow path and cavity size for a given frame size, though cartridge extension dimensions may vary. This model incorporates a balanced adjustment mechanism facilitating easy operation even under high pressures. Its sharp-edged orifice design minimizes flow variations due to changes in fluid viscosity. The floating style construction reduces the risk of internal binding caused by excessive installation torque or machining variations in the cavity or cartridge. The NCGCHBV fits into a T-18A cavity and boasts a capacity of 30 gpm (120 L/min) with a maximum operating pressure of 5000 psi (350 bar). It maintains minimal leakage rates at specified viscosities and features an adjustment range of up to 5.5 counterclockwise turns from fully closed to fully open. The valve has specific installation requirements including a hex size of 1-5/8 inches and an installation torque between 350 and 375 lbf ft. It includes an adjustment screw with an internal hex size of 5/32 inches and a locknut requiring torque between 80 and 90 lbf in. Weighing in at approximately 3 pounds, this model is suitable for various hydraulic applications requiring precise flow control capabilities.

Needle valves with reverse-flow check are fully adjustable orifices used to regulate flow. They are infinitely adjustable from fully closed up to the maximum orifice diameter. An integral high-capacity check valve provides unrestricted flow from port 2 to port 1. They are not pressure compensated.

  • 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.
  • 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.
