The Sun Hydraulics NCGCLBV (NCGCLBV) is a versatile needle valve with a reverse flow check, designed for precise flow regulation. This component allows for infinite adjustability from fully closed to the maximum orifice diameter, making it suitable for various applications requiring controlled fluid dynamics. The integral high-capacity check valve ensures unrestricted flow from port 2 to port 1, although the unit is not pressure compensated. Its design incorporates a sharp-edged orifice that minimizes variations in flow due to changes in fluid viscosity. The valve features a balanced adjustment mechanism that facilitates easy adjustments even under high pressure conditions, and its construction minimizes internal binding risks caused by excessive installation torque or machining variations. This model fits into a Cavity T-18A Series 4 with a capacity of 30 gpm (120 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). It has minimal leakage at maximum conditions, specified as 5 drops/min (0.3 cc/min) at 110 SUS (24 cSt). The adjustment range is defined by 5.5 counterclockwise turns from fully closed to fully open. For installation, the valve requires a torque between 350 and 375 lbf ft (474 to 508 Nm), with specific hex sizes for the valve body and adjustment components ensuring secure fitting and operation. The NCGCLBV model weighs approximately 3 lbs (1.35 kg) and employs Viton seals for reliability under various operational conditions. This needle valve is an excellent choice for applications demanding precise control over fluid flow without compromising on performance due to external factors such as viscosity changes or high-pressure environments.

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.
