The Sun Hydraulics NCFBHEN (NCFBHEN) is a versatile needle valve with a reverse flow check, designed for precise flow regulation in hydraulic systems. This valve provides an infinitely adjustable orifice, allowing for fine-tuning from fully closed to the maximum orifice diameter, making it suitable for applications requiring variable flow control. It features an integral high-capacity check valve that permits unrestricted flow from port 2 to port 1. The design is not pressure compensated, meaning the fixed orifice size will regulate flow based on the square root of the pressure differential across ports 1 and 2. This model incorporates a balanced adjustment mechanism for easy handling under high pressures and utilizes a sharp-edged orifice design to minimize flow variations due to viscosity changes. Additionally, it employs Sun's floating style construction to reduce the risk of internal parts binding from excessive installation torque or cavity-cartridge machining variations. The NCFBHEN fits into a Cavity T-16A Series 3 and has a capacity of up to 30 gpm (120 L/min). It can withstand a maximum operating pressure of 5000 psi (350 bar) and features minimal leakage at specified conditions. The adjustment range allows for up to 5.5 counterclockwise turns from fully closed to fully open, providing flexibility in diverse operational settings. Installation requires specific torques for both the valve and locknut, ensuring secure placement and optimal performance. The model weighs approximately 1.30 lb (0.60 kg) and includes options for Viton seal kits. This needle valve is ideal for applications needing reliable flow control with robust performance characteristics in demanding 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.
