The Sun Hydraulics DKJBXHV (DKJBXHV) is a high-performance hydraulic valve designed for precise fluid control in various applications. This normally closed, balanced poppet switching element operates efficiently under high-pressure conditions up to 5000 psi (350 bar) at both port 1 and port 2, with an external drain port open. It requires a minimum pilot pressure of 300 psi (20 bar) to shift from closed to open, ensuring reliable operation and enhanced control in complex hydraulic systems. The DKJBXHV features a unique balanced construction that allows for predictable switching and minimal internal part binding, thanks to its Sun floating style construction. This design helps accommodate excessive installation torque and potential cavity/cartridge machining variations, promoting longevity and consistent performance. The valve is characterized by an exceptionally low leakage rate between port 1 and port 2, typically less than 10 drops/min at maximum operating pressure, which translates to about 0.7 cc/min at 350 bar. This model is suited for applications requiring robust performance where precise fluid handling and pressure control are critical. The valve will automatically reseat when the pilot pressure drops below 145 psi (10 bar), adding an extra layer of safety and reliability. All ports on this valve are capable of accepting pressures up to 5000 psi (350 bar), making it versatile for various high-pressure applications. The DKJBXHV fits into a T19A cavity and belongs to the Series 4 product line from Sun Hydraulics, with a maximum flow capacity of about 120 gpm (480 L/min). Installation requires specific attention to torque settings between 350 - 375 lbf ft (474 - 508 Nm), ensuring secure fitting without compromising the valve's integrity or performance.

This is a normally closed, balanced poppet, switching element. When port 3 is blocked, the poppet remains in the closed position. Venting port 3 shifts it to the open position, provided there is sufficient pressure at port 2.
- Unique balanced construction provides predictable switching with 5000 psi (350 bar) at port 1 and port 2, with the external drain port open and a minimum pilot pressure of 300 psi (20 bar).
- 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).
- 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.
