The Sun Hydraulics NCGCKCV (NCGCKCV) is a versatile needle valve with reverse-flow check capabilities, designed to regulate flow through an adjustable orifice. This valve is infinitely adjustable from fully closed to the maximum orifice diameter, allowing precise control over fluid flow. It incorporates a high-capacity check valve that enables unrestricted flow from port 2 to port 1. However, it is important to note that this model is not pressure compensated. The NCGCKCV features a balanced adjustment mechanism, facilitating easy adjustments even under high-pressure conditions. The sharp-edged orifice design helps minimize flow variations due to changes in fluid viscosity. This model is part of the Series 4 capacity range and fits into the Cavity T-18A, with a maximum operating pressure of 5000 psi (350 bar) and a maximum flow capacity of 30 gpm (120 L/min). The valve's hex size measures 1-5/8 inches (41.3 mm), and it requires an installation torque between 350 and 375 lbf-ft (474 to 508 Nm). For adjustments, the internal hex size of the screw is 5/32 inches (4 mm), while the locknut hex size measures 9/16 inches (15 mm), with a locknut torque specification of 80 to 90 lbf-in (9 to 10 Nm). This model weighs approximately 3.00 lb (1.35 kg) and uses Viton seal kits for enhanced durability and performance. The NCGCKCV's construction incorporates Sun's floating style design, which minimizes internal binding risks due to excessive installation torque or machining variations in cavity/cartridge interfaces. This makes it suitable for various applications requiring precise flow regulation without pressure compensation across different operating conditions.
