The Sun Hydraulics NCECOBN (Material Number: NCECOBN) is a needle valve with a reverse flow check, designed for precise flow regulation in hydraulic systems. This model features an adjustable orifice that can be set from fully closed to the maximum diameter, allowing for customized flow control. It includes a high-capacity check valve that permits unrestricted flow from port 2 to port 1. However, it is important to note that this valve is not pressure compensated, meaning the flow regulation depends on the pressure differential between ports 1 and 2. The NCECOBN employs a balanced adjustment mechanism for easy tuning even under high pressure conditions, and its sharp-edged orifice design minimizes variations in flow due to changes in fluid viscosity. The valve\u2019s construction incorporates Sun's floating style design to reduce the risk of internal binding caused by excessive installation torque or machining variations. With a capacity of 3 gpm (11 L/min) and a maximum operating pressure of 5000 psi (350 bar), this model fits into cavity T-5A and is part of Series 2. It has an installation torque requirement of 45-50 lbf ft (61-68 Nm) and features an internal hex size adjustment screw measuring 5/32 inches (4 mm). The locknut requires a torque of 80-90 lbf in (9-10 Nm). The valve weighs approximately .40 lb (.20 kg) and utilizes Viton seals with seal kit number 990203006 available for maintenance needs.

Needle valves with reverse-flow check are fully adjustable orifices used to regulate flow. They are infinitely adjustable from fully closed up to the maximum orifice diameter. An integral high-capacity check valve provides unrestricted flow from port 2 to port 1. They are not pressure compensated.

  • All 2-port flow control cartridges are physically and functionally interchangeable (i.e. same flow path, same cavity for a given frame size). However, cartridge extension dimensions from the mounting surface may vary.
  • Because needle valves are non-compensating devices, the fixed orifice size will regulate flow through the valve in proportion to the square root of the pressure differential across ports 1 and 2.
  • A balanced adjustment mechanism allows for easy adjustment even at high pressures.
  • The sharp-edged orifice design minimizes flow variations due to viscosity changes.
  • Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
