The Sun Hydraulics DKJDEHV (DKJDEHV) is a sophisticated hydraulic valve designed for high-pressure applications, capable of handling up to 5000 psi (350 bar). This normally closed, balanced poppet switching element operates by blocking or venting an external port to control the open or closed state of the poppet. When the external vent port is blocked, the valve remains closed. Venting this port allows the valve to open, contingent on sufficient pressure at port 3. The DKJDEHV features a unique balanced construction that ensures predictable switching between ports. It requires a minimum pilot pressure of 300 psi (20 bar) to shift and can reseat itself when pilot pressure drops below 145 psi (10 bar). This model is particularly resilient against leakage, with a very low rate between port 1 and port 2 under maximum pressure conditions. For optimal performance, this valve can be paired with Sun\u2019s model DAA solenoid pilot valve, which matches its specifications for pilot flow requirements and leakage rates. The DKJDEHV benefits from Sun\u2019s floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. This valve is suitable for use in systems requiring precise control over high-pressure fluid handling, with robust sealing between its ports and accommodating up to 120 gpm (480 L/min). Its design and capabilities make it an ideal choice for demanding hydraulic applications where reliability and performance are critical.

This is a normally closed, balanced poppet, switching element. When the external vent port is blocked, the poppet remains in the closed position. Venting the external port 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 port 1 and port 2, with the external drain port open and a minimum pilot pressure of 300 psi (20 bar).
- The external -4 SAE vent port may be directly connected to a pilot switching valve. The pilot valve should have a leakage rate of less than 10 drops/min (0,7 cc/min). and be able to satisfy the pilot flow requirements. Sun model DAA*-*** solenoid pilot valve is ideal for this application.
- 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).
- 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.
