The Sun Hydraulics NCEBYAN (NCEBYAN) is a precision-engineered needle valve with a reverse-flow check, designed for meticulous flow regulation through fully adjustable orifices. This valve allows for infinite adjustment from fully closed to the maximum orifice diameter, making it ideal for applications requiring precise flow control. It features an integral high-capacity check valve that ensures unrestricted flow from port 2 to port 1. The NCEBYAN model is not pressure compensated, meaning the fixed orifice size will regulate flow proportionally to the square root of the pressure differential across ports 1 and 2. This model includes a balanced adjustment mechanism that facilitates easy adjustments even under high pressures, and its sharp-edged orifice design minimizes flow variations due to changes in fluid viscosity. Physically and functionally interchangeable with other 2-port flow control cartridges within its frame size, this needle valve offers versatility in various setups. However, note that cartridge extension dimensions may vary from the mounting surface. The valve incorporates Sun's floating style construction to reduce internal binding risks due to excessive installation torque or machining variations in cavity-cartridge assemblies. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended, as exposure to petroleum-based fluids can damage these seals. The NCEBYAN has a capacity of 12 gpm (45 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). It exhibits minimal leakage at standard conditions and comes with detailed specifications for installation torque and adjustment mechanisms. With a compact design weighing just .40 lb (.20 kg), it is compatible with Viton seal kits for enhanced durability in demanding environments.
