The Sun Hydraulics NCGBKDN (NCGBKDN) is a versatile needle valve with reverse flow check, designed for precise flow regulation in hydraulic systems. This component features an adjustable orifice that allows for infinite control from fully closed to the maximum diameter, ensuring optimal performance in various applications. It incorporates a high-capacity check valve that enables unrestricted flow from port 2 to port 1. While not pressure compensated, this needle valve maintains consistent performance through its balanced adjustment mechanism, facilitating easy adjustments even under high pressure conditions. The sharp-edged orifice design minimizes flow variation due to viscosity changes, making it suitable for diverse fluid dynamics. The NCGBKDN model is compatible with Sun's Series 4 cavity T-18A and offers a substantial capacity of up to 60 gpm (240 L/min) with a maximum operating pressure of 5000 psi (350 bar). The valve's construction includes a floating style design to reduce the risk of internal binding caused by excessive installation torque or machining variations. This ensures reliability and longevity in demanding environments. For systems utilizing phosphate ester fluids, the cartridge can be configured with EPDM seals; however, these seals are not compatible with petroleum-based fluids and may incur damage if exposed. The valve's installation requires specific torque settings: 350 - 375 lbf ft (474 - 508 Nm) for installation and 80 - 90 lbf in (9 - 10 Nm) for the locknut. With its robust design and precise control capabilities, the Sun Hydraulics NCGBKDN needle valve is an essential component in hydraulic systems requiring reliable flow regulation and reverse flow management.

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.
