The Sun Hydraulics DKDCEHV (DKDCEHV) is a high-performance hydraulic valve designed for demanding applications requiring precise control and reliability. This normally closed, balanced poppet, switching element operates effectively with a pilot pressure at port 3, which shifts the valve to the open position. It features a unique balanced construction that ensures predictable switching with robust capabilities, handling up to 5000 psi (350 bar) at both ports 1 and 2 when the external drain is open. The minimum pilot pressure required to initiate the shift is 400 psi (30 bar). The DKDCEHV valve boasts positive seals between port 2 and the pilot area and maintains hydraulic balance between port 1 and port 2. It showcases an impressively low leakage rate, typically less than 10 drops/min at 5000 psi (0.7 cc/min at 350 bar). The valve will reseat when pilot pressure falls below 145 psi (10 bar). Designed for versatility, it uses the same cavity as unbalanced logic valves of the same frame size (T11A Series), making it a functional replacement for those units. This model can be configured in either an external atmospheric vent (X control) or static external drain (E control). The X control setup refers to three-port vented logic elements that are atmospherically referenced, providing solutions for circuits originally using non-vented valves. For new applications or in environments where moisture ingress or external leakage over time is a concern, four-port valves or an E control configuration are recommended. All ports on this valve can withstand pressures up to 5000 psi (350 bar), and it incorporates Sun's floating style construction which minimizes internal parts binding due to installation torque or machining variations of the cavity/cartridge. This design ensures consistent performance even under varied installation 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 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.
