The Sun Hydraulics DKHCXHV (DKHCXHV) is a high-performance, normally closed hydraulic valve designed for advanced fluid power applications. This balanced poppet, switching element operates with a pilot pressure at port 3, which when activated, shifts the valve to an open position. Crafted to handle maximum pressures up to 5000 psi (350 bar) at ports 1 and 2 with an external drain open, it requires a minimum pilot pressure of 300 psi (20 bar) to shift effectively. The DKHCXHV is distinguished by its minimal leakage rate, typically less than 10 drops/min at 5000 psi (about 0.7 cc/min at 350 bar), ensuring efficient operation and reduced fluid loss. The valve will automatically reseat once the pilot pressure falls below 145 psi (10 bar). It shares the same cavity as unbalanced logic valves of the same frame size (T17A Series 3), allowing for straightforward replacement in existing systems. Available in two configurations\u2014external atmospheric vent (X control) and static external drain (E control)\u2014the DKHCXHV provides flexibility depending on specific application needs. The X control variant references atmospheric pressure and is ideal for troubleshooting in circuits originally using non-vented valves. For new installations or where external leakage and moisture ingress into the spring chamber are concerns, the four-port valve configuration or E control option with connected drain is recommended. This valve also incorporates Sun\u2019s floating style construction which minimizes potential internal binding caused by installation torque or variations in cavity/cartridge machining. With a flow capacity of up to 60 gpm (240 L/min), this robust valve meets demanding hydraulic system requirements while maintaining precise control and reliability across various 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.
