The Sun Hydraulics DKDCXHV (DKDCXHV) is a high-performance hydraulic valve designed for robust fluid control in demanding applications. This model features a normally closed, balanced poppet switching element that shifts to the open position under pilot pressure at port 3. Built to handle pressures up to 5000 psi (350 bar) at ports 1 and 2, with an external drain open and a minimum pilot pressure of 400 psi (30 bar), it ensures reliable operation under high-pressure conditions. The DKDCXHV valve showcases unique balanced construction that facilitates predictable switching and minimal leakage\u2014typically less than 10 drops/min at 5000 psi or 0.7 cc/min at 350 bar between ports 1 and 2. It reseats when pilot pressure falls below 145 psi (10 bar), enhancing its functional reliability. The valve is compatible with the T11A cavity and belongs to Series 1, supporting a flow capacity of up to 15 gpm (60 L/min). This model offers flexibility in control configurations, available in external atmospheric vent (X control) or static external drain (E control). The X control variant references atmospheric pressure and helps solve issues in circuits using non-vented valves by allowing for external leaks or moisture ingress over time; however, four-port valves are recommended for new applications to avoid these issues. Alternatively, converting an X control to an E control is straightforward by removing the vent plug. Furthermore, the DKDCXHV incorporates Sun's floating style construction which minimizes potential internal binding due to excessive installation torque or variations in cavity/cartridge machining. This feature ensures durable and stable performance even under varying installation conditions. The valve accepts a maximum operating pressure of up to 5000 psi (350 bar) across all ports, making it a versatile choice for various hydraulic systems requiring precise fluid management with high reliability.

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 400 psi (30 bar).
- These valves have positive seals between port 2 and the pilot area.
- These valves are hydraulically balanced between port 1 and port 2.
- 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.
- 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.
