The Sun Hydraulics DKFCXHV (DKFCXHV) is a high-performance hydraulic valve designed for advanced fluid control in various applications. It features a normally closed, balanced poppet, switching element that ensures reliable operation under high-pressure conditions. This valve is activated by pilot pressure at port 3, which shifts the valve to an open position when the pressure threshold is met. The DKFCXHV can handle up to 5000 psi or 350 bar at ports 1 and 2 with an external drain open, requiring a minimum pilot pressure of 300 psi or 20 bar to shift. The leakage rate between port 1 and port 2 is remarkably low, typically less than 10 drops per minute at maximum operating pressure, ensuring efficient performance and minimal fluid loss. The valve will automatically reseat when the pilot pressure falls below 145 psi or 10 bar. This model uses the T2A cavity and belongs to Series 2, supporting up to 30 gpm or 120 L/min capacity. For installation flexibility, it offers two control configurations: external atmospheric vent (X control) and static external drain (E control). The X control valves are atmospherically referenced and help resolve issues in circuits originally using non-vented valves by preventing external leaks and moisture ingress into the spring chamber over time. For new installations or where enhanced reliability is needed, four-port valves are recommended. Moreover, the DKFCXHV incorporates Sun's floating style construction which minimizes potential internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. This design feature contributes significantly to the overall durability and reliability of the valve in demanding operational conditions.

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.
