The Sun Hydraulics DKFCXHN (DKFCXHN) is a high-performance hydraulic valve designed for precise fluid control in various applications. This model is a normally closed, balanced poppet, switching element that operates effectively under a maximum pressure of 5000 psi (350 bar) at both ports 1 and 2. The valve transitions to an open state when pilot pressure at port 3 reaches a minimum of 300 psi (20 bar). It features exceptional sealing capabilities, with leakage between ports 1 and 2 maintained at less than 10 drops per minute at maximum pressure, ensuring efficient operation and minimal fluid loss. The DKFCXHN valve is versatile with its ability to use the same cavity as unbalanced logic valves of the same frame size, making it a functional replacement for various systems. It offers configurations in external atmospheric vent (X control) or static external drain (E control), enhancing adaptability for different circuit requirements. The X control variant references atmospheric pressure and addresses common issues in circuits initially designed with non-vented valves by preventing external leaks and moisture ingress into the spring chamber. For new installations, four-port valves are recommended, although the E control option allows connection of the external vent port to a drain for enhanced performance. This model also incorporates Sun's floating style construction which minimizes internal parts binding\u2014a common issue caused by excessive installation torque or cavity/cartridge machining variations. With a capacity of up to 30 gpm (120 L/min) and minimal pilot volume displacement required for shifting (.02 in\u00b3/0.33 cc), the DKFCXHN ensures reliable and responsive operation across various hydraulic applications.

This is a normally closed, balanced poppet, switching element. Pilot pressure at port 3 shifts the valve to the open position.
- Unique balanced construction provides predictable switching with 5000 psi (350 bar) at both ports 1 and 2, with the external drain open and a minimum pilot pressure of 300 psi (20 bar).
- Leakage rate between port 1 and port 2 is very low, typically less than 10 drops/min. at 5000 psi (0,7 cc/min at 350 bar).
- Valve will reseat when the pilot pressure falls below 145 psi (10 bar).
- These 3-port balanced logic valves use the same cavity as unbalanced logic valves of the same frame size and can be considered functional replacements.
- Available in external atmospheric vent (X control) or static external drain (E control) configurations.
- Three-port vented logic elements with the X control are atmospherically referenced and considered problem solvers for existing circuits using non-vented valves. Over time, these valves will eventually leak externally and/or allow moisture into the spring chamber. Four-port valves are recommended for new applications. Alternately, the external vent port can be connected to drain if the static drain port option (control option E) is selected. Removing the vent plug will convert an X control to an E control.
- These valves are hydraulically balanced between port 1 and port 2.
- Port 1 and port 2 are fully sealed from port 3.
- All ports will accept 5000 psi (350 bar).
- 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.
