The Sun Hydraulics DOJDEHV (Material Number: DOJDEHV) is a normally open, balanced poppet switching element designed for high-pressure hydraulic applications. This valve remains open when the external vent port is blocked and shifts to a closed position upon venting the external port, provided there is sufficient pressure at port 3. It features a unique balanced construction that ensures predictable switching performance under pressures up to 5000 psi (350 bar) at ports 1 and 2, with an external drain port open and a minimum pilot pressure of 300 psi (20 bar). The valve's design includes an external 4 SAE vent port, which can be directly connected to a pilot switching valve with minimal leakage rates. The Sun model DAA solenoid pilot valve is recommended for this application due to its compatibility. This hydraulically balanced valve between ports 1 and 2 exhibits very low leakage rates, typically less than 10 drops per minute at maximum operating pressures. Ports are fully sealed from each other, ensuring robust performance in demanding environments. The valve accepts up to 5000 psi across all ports and incorporates Sun's floating style construction to minimize binding risks due to installation torque or machining variations. The DOJDEHV fits into cavity T19A and belongs to Series 4 with a capacity of handling flow rates up to 120 gpm (480 L/min). It requires a minimum pilot pressure of 300 psi (20 bar) for shifting and has specific installation torque specifications of 350 - 375 lbf ft (475 - 508 Nm). A Viton seal kit is available under part number: 990019006, ensuring reliable sealing in hydraulic systems.

This is a normally open, balanced poppet, switching element. When the external vent port is blocked, the poppet remains in the open position. Venting the external port shifts it to the closed 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.
- Valve will open when the pilot pressure falls below 145 psi (10 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).
- 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.
