The Sun Hydraulics NCEBLCV (Material Number: NCEBLCV) is a needle valve with reverse flow check, designed to regulate flow with precision. This valve is fully adjustable from a closed position to the maximum orifice diameter, allowing for precise control of fluid flow. It includes an integral high-capacity check valve that enables unrestricted flow from port 2 to port 1, although it is not pressure compensated. The design ensures interchangeability among all 2-port flow control cartridges, maintaining the same flow path and cavity compatibility for a given frame size, even though cartridge extension dimensions might differ. The non-compensating nature of the needle valve means that the orifice size regulates flow proportionally to the square root of the pressure differential across ports 1 and 2. A balanced adjustment mechanism facilitates easy adjustments even under high-pressure conditions, while the sharp-edged orifice minimizes flow variations due to viscosity changes. The Sun Hydraulics NCEBLCV features a floating style construction that reduces the risk of internal parts binding due to excessive installation torque or machining variations in cavity-cartridge configurations. It supports a capacity of 12 gpm (45 L/min) and operates at a maximum pressure of 5000 psi (350 bar). The valve has specific installation requirements including a hex size of 1-1/8 inches and an installation torque range between 45-50 lbf ft (61-68 Nm). Its adjustment screw requires a 5/32 inch internal hex size, while the locknut has a hex size of 9/16 inches with a torque range of 80-90 lbf in (9-10 Nm). The model weighs approximately .40 lb (.20 kg) and uses Viton seals for effective performance in various applications.

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.
  • Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
  • 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.
