The Sun Hydraulics NCECKBV (NCECKBV) is a highly functional needle valve with a reverse flow check, designed to regulate hydraulic flow with precision. This valve features an infinitely adjustable orifice, allowing for fine-tuned control from fully closed to the maximum orifice diameter, while its integral high-capacity check valve 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 its ports. The valve's construction includes a balanced adjustment mechanism for ease of use even under high-pressure conditions and a sharp-edged orifice design that minimizes flow variations due to changes in fluid viscosity. The NCECKBV model is built using Sun's floating style construction, which helps prevent internal binding caused by excessive installation torque or machining variations in the cavity and cartridge. It fits into cavity T-5A and offers a series 2 capacity of up to 3 gpm (11 L/min) with a maximum operating pressure of 5000 psi (350 bar). The valve has minimal leakage rates at specified conditions and allows for up to 5.5 counterclockwise turns from fully closed to fully open. Installation requires specific torque settings: the valve hex size is 1-1/8 inches (28.6 mm) with an installation torque of 45-50 lbf ft (61-68 Nm), while the adjustment screw requires a 5/32 inch (4 mm) internal hex size. Additionally, the locknut has a hex size of 9/16 inches (15 mm) and should be tightened with an 80-90 lbf in (9-10 Nm) torque. Weighing just .40 lb (.20 kg), this model also includes compatibility with Viton seal kits for enhanced durability and performance in various applications.

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.
