The Sun Hydraulics NCGBHDV (NCGBHDV) is a versatile needle valve with a reverse flow check, designed for precise flow regulation in hydraulic systems. This fully adjustable orifice allows for infinite adjustment from fully closed to the maximum orifice diameter, providing users with control over fluid dynamics. The valve includes an integral high-capacity check valve that ensures unrestricted flow from port 2 to port 1. Notably, it is not pressure compensated, meaning the flow regulation is dependent on the pressure differential across ports 1 and 2. The valve's balanced adjustment mechanism facilitates easy tuning even under high-pressure conditions, while the sharp-edged orifice design minimizes flow variations due to changes in fluid viscosity. This cartridge-style valve features Sun's floating style construction to reduce the risk of internal parts binding due to excessive installation torque or machining variations. It fits into a T-18A cavity and belongs to Series 4, offering a capacity of up to 60 gallons per minute (240 L/min) with a maximum operating pressure of 5000 psi (350 bar). The valve exhibits minimal leakage at standard fluid viscosities and includes an adjustment mechanism that allows for up to five counterclockwise turns from fully closed to fully open. The NCGBHDV model is compatible with EPDM seals for use in systems utilizing phosphate ester fluids; however, exposure to petroleum-based fluids can damage these seals. Weighing approximately 3 pounds (1.35 kg), this model requires specific installation torques and adjustments: a valve hex size of 1-5/8 inches (41.3 mm), an internal hex size of 5/32 inches (4 mm) for the adjustment screw, and locknut torque specifications between 80-90 lbf-in (9-10 Nm).

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.
