The Sun Hydraulics NCEBLAV (Material Number: NCEBLAV) is a needle valve with a reverse-flow check, specifically designed for regulating flow in hydraulic systems. This valve features an infinitely adjustable orifice, allowing users to precisely control flow from fully closed to the maximum orifice diameter. It incorporates an integral high-capacity check valve that enables unrestricted flow from port 2 to port 1, although it is not pressure compensated. The NCEBLAV model is part of the Series 2 cartridges, which are interchangeable with other 2-port flow control cartridges of the same frame size and cavity. However, extension dimensions from the mounting surface may vary. The valve's operation is based on a balanced adjustment mechanism that facilitates easy adjustments even under high pressure conditions. Its sharp-edged orifice design minimizes variations in flow due to changes in fluid viscosity. Cartridges equipped with EPDM seals are suitable for systems utilizing phosphate ester fluids but should not be exposed to petroleum-based fluids as this can damage the seals. The construction of this model uses Sun's floating style design, which reduces the risk of internal parts binding due to excessive installation torque or machining variations in the cavity and cartridge. The NCEBLAV has a capacity of 12 gpm (45 L/min) with a maximum operating pressure of 5000 psi (350 bar). It allows up to five counterclockwise turns from fully closed to fully open positions and features specific installation requirements such as a valve hex size of 1-1/8 inches and an installation torque range between 45 and 50 lbf ft (61 - 68 Nm). The model weighs approximately .40 lb (.20 kg) and utilizes Viton seal kits for optimal performance.

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.
