The Sun Hydraulics NCGCKDN (NCGCKDN) is a needle valve with a reverse-flow check, designed to provide precise flow regulation in hydraulic systems. This valve features an adjustable orifice that can be set from fully closed to the maximum diameter, allowing for versatile control over fluid flow. It includes an integral high-capacity check valve that ensures unrestricted flow from port 2 to port 1. Notably, this model is not pressure compensated, meaning the flow regulation is dependent on the pressure differential between ports 1 and 2, following a square root relationship. The NCGCKDN model is part of the Series 4 cartridge valves and fits into cavity T-18A. It has a capacity of 30 gallons per minute (120 liters per minute) and can withstand a maximum operating pressure of 5000 psi (350 bar). The valve's design incorporates a sharp-edged orifice to minimize flow variations due to changes in fluid viscosity, and it features Sun's floating style construction to reduce the risk of internal binding caused by installation torque or machining variations. For easy adjustment even under high pressures, the valve includes a balanced adjustment mechanism with up to five counterclockwise turns from fully closed to fully open. The hex sizes for installation and adjustment are designed for standard tools, ensuring straightforward maintenance and operation. The valve's robust construction allows it to handle demanding applications while maintaining minimal leakage rates. Additionally, it supports various sealing options like Viton for enhanced durability in different environmental conditions.
