The Sun Hydraulics NCECKEN (Material Number: NCECKEN) is a needle valve with a reverse flow check, designed for precise flow regulation by providing an infinitely adjustable orifice from fully closed to the maximum diameter. This model features an integral high-capacity check valve that allows unrestricted flow from port 2 to port 1, making it suitable for applications requiring controlled fluid flow in one direction while permitting free flow in the reverse. The valve operates without pressure compensation, meaning the orifice size will regulate flow based on the square root of the pressure differential across ports 1 and 2. It incorporates a balanced adjustment mechanism for easy adjustments even under high pressures and uses a sharp-edged orifice design to minimize flow variations due to viscosity changes. The Sun floating style construction minimizes potential binding of internal parts due to installation torque or machining variations. The valve fits into Cavity T-5A, Series 2, with a capacity of 3 gpm (11 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). It has minimal leakage at 5 drops/min (0.3 cc/min) under specified conditions. The adjustment allows for up to 5.5 counterclockwise turns from fully closed to open, with specific torque requirements for installation and adjustments provided. The valve is equipped with Viton seals and weighs approximately 0.40 lb (0.20 kg).
