The Sun Hydraulics CNFCXDN (CNFCXDN) is a precision-engineered hydraulic check valve designed for high-pressure applications, capable of handling up to 5000 psi (350 bar) at ports 1 and 2. This valve features a free flow from port 1 to port 2, while incorporating a customer-specified orifice to restrict flow from port 2 to port 1, enhancing its utility in various hydraulic circuits. The orifice range for this model spans from 0.016 to 0.127 inches (0.4 to 3.2 mm), allowing for customization based on specific system requirements. Constructed with corrosion-resistant materials, the CNFCXDN is suitable for use in environments where corrosive elements are present. This durability is further supported by Sun Hydraulics' floating style construction which minimizes the risk of internal parts binding\u2014a common issue arising from excessive installation torque or variations in cavity/cartridge machining. The valve's design also includes a T5A cavity and belongs to the Series 2 category, with a capacity of up to 30 gpm (120 L/min). For maintenance and replacement, it utilizes Viton seals (part number: 990203006), ensuring reliable sealing and performance longevity under varying operational conditions. Moreover, this model's versatility is highlighted by its adaptability in systems where reverse flow control valves are required, demonstrating its capability as both a check and flow control valve depending on the configuration. The specific orifice diameter selected by the customer is conveniently stamped on one of the cartridge\u2019s hex faces for easy identification during maintenance or system adjustments.

Free-flow, nose-to-side check valves with a bypass orifice allow free flow from port 1 to port 2. A customer specified orifice is included to restrict flow from port 2 to port 1. See technical data below for orifice range.
- Two-port check valves share the same cavity for a given frame size, however, pay close attention as flow paths may be in opposite directions.
- Will accept 5000 psi (350 bar) at ports 1 and 2.
- Valves with the opposite flow path (free flow from 2 to 1) are considered flow controls and may be found listed as fixed orifice, non-pressure compensated flow control valve with reverse flow check.
- The customer specified orifice diameter is stamped on one of the cartridge's hex faces.
- Corrosion resistant cartridge valves are intended for use in corrosive environments and are identified by the model code suffix /AP or /LH (see CONFIGURATION section). For further details, please see the Materials of Construction page.
- 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.
