The Sun Hydraulics DKJRXHV (DKJRXHV) is a high-performance hydraulic valve designed for precise control in fluid power applications. This model features a normally closed, balanced poppet switching element that operates effectively under high-pressure conditions up to 5000 psi (350 bar). The valve's operation is contingent on the status of the vent port (port 4); when this port is blocked, the poppet remains closed. Conversely, venting this port allows the valve to shift to an open position, assuming sufficient pilot pressure at port 3. The DKJRXHV ensures minimal leakage, with a rate typically less than 10 drops per minute between ports 1 and 2 at maximum pressure. It incorporates Sun Hydraulics' floating style construction which minimizes internal part binding and potential damage from installation torque or cavity/cartridge machining variations. Each of the valve\u2019s ports can withstand pressures up to 5000 psi, and it requires a minimum pilot pressure of 300 psi (20 bar) to shift. This model supports a maximum flow capacity of 120 gpm (480 L/min), making it suitable for various heavy-duty applications where reliable switching and fluid control are critical. The valve also features robust sealing between its ports to ensure efficient operation without cross-port contamination. Additionally, it reseats automatically when pilot pressure drops below 145 psi (10 bar), enhancing its operational safety and reliability. Designed for ease of installation and maintenance, the DKJRXHV has a hex size of 1-5/8 inches (41.3 mm) and an installation torque range of 350 -375 lbf ft (474 -508 Nm). Its compact form factor weighs only 2.50 lbs (1.15 kg), facilitating integration into existing systems without requiring significant space or structural modifications.

This is a normally closed, balanced poppet, switching element. When the vent port (port 4) is blocked, the poppet remains in the closed position. Venting port 4 shifts it to the open position, provided there is sufficient pressure at port 3.
- Unique balanced construction provides predictable switching with 5000 psi (350 bar) at both ports 1 and 2, with the vent (port 4) open and a minimum pilot pressure of 400 psi (30 bar) at port 3.
- Port 1 and port 2 are fully sealed from port 3 and port 4. Ports 3 and 4 are positively sealed.
- 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).
- Port 4 may be externally connected to a pilot switching valve. The pilot valve should have a leakage rate of less than 10 drops/min. and be able to satisfy the pilot flow requirements. Sun model DAA*-*** solenoid pilot valve is ideal for this application.
- 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.
