The Sun Hydraulics NCFCLAV (NCFCLAV) is a versatile needle valve featuring an integral high-capacity check valve, designed to offer unrestricted flow from port 2 to port 1 while allowing for precise flow regulation through its fully adjustable orifice. This model is part of the T-16A cavity series and has a capacity of up to 15 gpm (60 L/min) with a maximum operating pressure of 5000 psi (350 bar). It is important to note that these needle valves are non-pressure compensated, meaning the flow regulation is dependent on the pressure differential across ports 1 and 2. The design includes a balanced adjustment mechanism that facilitates easy adjustments even under high pressures, along with a sharp-edged orifice that reduces flow variations due to viscosity changes. The floating style construction minimizes potential binding of internal parts caused by excessive installation torque or machining variations in the cavity/cartridge. For installation, the valve requires a hex size of 1 1/4 inches (31.8 mm) with an installation torque between 150 and 160 lbf ft (203 and 217 Nm). The adjustment screw features an internal hex size of 5/32 inches (4 mm), while the locknut requires a hex size of 9/16 inches (15 mm) with a torque specification between 80 and 90 lbf in (9 and 10 Nm). Weighing approximately 1.30 lb (0.60 kg), this cartridge also supports interchangeability across all two-port flow control functions within its frame size, although extension dimensions from the mounting surface may vary.
