The Sun Hydraulics NCGBYCV (NCGBYCV) is a needle valve with a reverse-flow check, designed to provide precise flow regulation in hydraulic systems. It features an infinitely adjustable orifice, allowing users to control flow from fully closed to the maximum orifice diameter. The integrated high-capacity check valve ensures unrestricted flow from port 2 to port 1, although it is important to note that this valve is not pressure compensated. This means that the fixed orifice size regulates flow in proportion to the square root of the pressure differential across ports 1 and 2. This model is part of the 2-port flow control cartridges range, which are physically and functionally interchangeable within a given frame size. However, dimensions may vary from the mounting surface. The valve incorporates a balanced adjustment mechanism for easy adjustments even under high pressures and features a sharp-edged orifice design that minimizes flow variations due to changes in fluid viscosity. The NCGBYCV model is equipped with EPDM seals for compatibility with phosphate ester fluids, but caution should be taken as exposure to petroleum-based fluids can damage these seals. It utilizes Sun's floating style construction to prevent internal parts from binding due to installation torque or machining variations. Key specifications include a T-18A cavity size with Series 4 capacity of up to 60 gpm (240 L/min), and it can operate at a maximum pressure of 5000 psi (350 bar). The valve has minimal leakage rates and allows for up to five counterclockwise turns for full adjustment from closed to open positions. Installation requires specific torque values, ensuring secure fitting without compromising performance. The model weighs approximately 3 lbs (1.35 kg) and uses Viton seal kits for maintenance purposes.

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.
