The Sun Hydraulics NCGBHAV (NCGBHAV) is a precision-engineered needle valve with a reverse flow check, designed for seamless flow regulation in hydraulic systems. This component features an adjustable orifice that allows for precise control from fully closed to the maximum orifice diameter, ensuring optimal performance across various applications. The integral high-capacity check valve facilitates unrestricted flow from port 2 to port 1, although the valve is not pressure compensated. This needle valve is part of the 2-port flow control cartridge line, which are interchangeable in terms of function and physical dimensions within the same frame size. It operates based on the principle that flow regulation through the non-compensating device is proportional to the square root of the pressure differential between ports 1 and 2. The balanced adjustment mechanism enhances ease of use even under high pressure conditions, while the sharp-edged orifice design minimizes flow variations caused by changes in fluid viscosity. The NCGBHAV model incorporates Sun's floating style construction to reduce internal part binding due to excessive installation torque or cavity-cartridge machining variations. It has a capacity of 60 gpm (240 L/min) with a maximum operating pressure of 5000 psi (350 bar). The valve's hex size is 1-5/8 inches (41.3 mm), with an installation torque range of 350-375 lbf ft (474-508 Nm). For adjustments, it requires up to five counterclockwise turns from fully closed to fully open, with an internal hex size adjustment screw of 5/32 inches (4 mm). The locknut has a hex size of 9/16 inches (15 mm) and requires a torque range of 80-90 lbf in (9-10 Nm). This model weighs approximately 3.00 lb (1.35 kg) and includes Viton seals as standard for compatibility with various fluid types.

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.
  • 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.
