The Sun Hydraulics CNKCXBN (CNKCXBN) is a highly versatile and robust check valve designed for hydraulic applications requiring reliable flow control and direction. This model features a freeflow, nose-to-side configuration allowing unrestricted flow from port 1 to port 2, while a customer-specified orifice restricts flow in the reverse direction from port 2 to port 1. The orifice range for this valve spans from 0.4 mm to 9 mm, offering flexibility in application according to specific system requirements. Engineered for performance in Sun's T18A cavity at reduced capacities, the CNKCXBN achieves its optimal functionality when installed in the T18AU cavity, supporting up to 180 gpm (680 L/min). It is built to withstand maximum operating pressures of up to 5000 psi (350 bar) at both ports. Notably, the valve incorporates Sun's floating style construction which minimizes internal part binding and potential malfunctions caused by excessive installation torque or variations in cavity/cartridge machining. This model is direct-acting, making it suitable for systems where fast response and tolerance to contamination are critical. The dimensions include a hex size of 1-5/8 inches (41.3 mm), and an installation torque ranging between 350 - 375 lbf-ft (474 - 508 Nm). The overall weight of the CNKCXBN model is approximately 2.10 lbs (0.95 kg), and it uses Viton seals for enhanced durability against high temperatures and chemical interactions. In summary, the Sun Hydraulics CNKCXBN check valve is an essential component for hydraulic systems requiring precise flow control with high reliability under varying operational conditions. Its design ensures compatibility with standard cavities while offering customization through selectable orifice sizes stamped directly on the cartridge for easy identification and maintenance.

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.
- These valves will work in Sun's standard T-18A cavity at lower capacity. To realize the full stated capacity, the T-18AU cavity should be used.
- 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.
- Will accept 5000 psi (350 bar) at ports 1 and 2.
- The customer specified orifice diameter is stamped on one of the cartridge's hex faces.
- 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.
