The Sun Hydraulics DKJBXHN (DKJBXHN) is a high-performance hydraulic valve designed for robust and efficient fluid control in various hydraulic systems. This model is a normally closed, balanced poppet switching element that operates effectively under high-pressure conditions up to 5000 psi (350 bar) at both port 1 and port 2. It features a unique construction that allows predictable switching and minimal leakage, with a leakage rate typically less than 10 drops/min at maximum pressure. The valve's operation is contingent on the pilot pressure; it requires a minimum of 300 psi (20 bar) to shift and will reseat when the pressure falls below 145 psi (10 bar). Its balanced design between port 1 and port 2 ensures stability and reliability in performance. Additionally, the DKJBXHN incorporates Sun's floating style construction which minimizes internal parts binding\u2014a common issue caused by excessive installation torque or variations in cavity/cartridge machining. Designed to handle up to 120 gpm (480 L/min), this valve is suitable for high-capacity systems. It also supports an external drain port open condition, ensuring versatility in application across different hydraulic setups. The valve\u2019s specifications also include a hex size of 1-5/8 inches (41.3 mm) and an installation torque range of 350 - 375 lbf\u00b7ft (474 - 508 Nm), making it adaptable to various industrial installations without compromising its operational integrity. The use of Viton seals enhances its durability and compatibility with different hydraulic fluids, ensuring long service life and reduced maintenance needs.

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.
