The Sun Hydraulics NCGBLCN (NCGBLCN) is a needle valve with a reverse flow check, designed as a fully adjustable orifice for regulating flow. This component is capable of infinite adjustment from fully closed to the maximum orifice diameter, allowing for precise control over fluid movement. It features an integral high-capacity check valve that enables unrestricted flow from port 2 to port 1, although it is not pressure compensated. The design ensures that all 2-port flow control cartridges are physically and functionally interchangeable within the same frame size, though extension dimensions may vary. Due to its non-compensating nature, the fixed orifice size regulates flow in proportion to the square root of the pressure differential across ports 1 and 2. The NCGBLCN model incorporates a balanced adjustment mechanism for easy manipulation even under high pressures and employs a sharp-edged orifice design which minimizes flow variations due to viscosity changes. Cartridges with EPDM seals are suitable for systems using phosphate ester fluids; however, exposure to petroleum-based products will damage these seals. The product also utilizes Sun's floating style construction to prevent internal parts binding due to excessive installation torque or machining variations. Key specifications include a cavity type T-18A Series 4 with a capacity of 60 gpm (240 L/min) and a maximum operating pressure of 5000 psi (350 bar). The valve allows for up to 55 counterclockwise turns from fully closed to fully open positions. The model has an installation torque range of 350 \u2013 375 lbf ft (474 \u2013 508 Nm) and features various hex sizes for adjustments and locknuts. It weighs approximately 3 pounds (1.35 kg) and is compatible with Viton seal kits identified by part number 990018006.

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.
