The Sun Hydraulics NCGBLBV (Material Number: NCGBLBV) is a versatile needle valve with a reverse flow check, designed for precise flow regulation. It offers an adjustable orifice that can be set from fully closed to the maximum diameter, allowing for fine-tuned control of hydraulic systems. The valve features an integrated high-capacity check valve that ensures unrestricted flow from port 2 to port 1, making it ideal for applications requiring seamless fluid direction changes. Despite its robust capabilities, it is not pressure compensated, meaning the flow regulation depends on the pressure differential between ports 1 and 2. This product is part of Sun's interchangeable 2-port flow control cartridges, maintaining consistent flow paths and cavity dimensions across similar frame sizes but with varying extension dimensions. The NCGBLBV incorporates a balanced adjustment mechanism for easy operation even under high-pressure conditions and employs a sharp-edged orifice design to minimize variations due to fluid viscosity changes. Cartridges with EPDM seals are suitable for systems using phosphate ester fluids but should not be exposed to petroleum-based substances as this could damage the seals. The floating style construction reduces the risk of internal binding due to installation torque or machining variations. Key specifications include a T-18A cavity series with a capacity of 60 gpm (240 L/min) and a maximum operating pressure of 5000 psi (350 bar). The valve features minimal leakage at specified conditions and allows for up to 5.5 counterclockwise turns from fully closed to open positions. Installation requires specific torque values for optimal performance, with detailed hex size requirements provided for adjustment and locknut components. With its durable construction and precise control capabilities, this needle valve is an essential component in hydraulic systems demanding reliable performance and adaptability.

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.
