The Sun Hydraulics DOHDEHV (DOHDEHV) is a normally open, balanced poppet switching element designed for high-pressure hydraulic applications. This component maintains an open position when the external vent port is blocked, and shifts to a closed position when the vent port is opened, provided there is adequate pressure at port 3. Its unique balanced construction allows for predictable switching at pressures up to 5000 psi (350 bar) at ports 1 and 2, with a minimum pilot pressure of 300 psi (20 bar). The valve features very low leakage between ports 1 and 2, typically less than 10 drops per minute at maximum pressure, ensuring efficient operation. The external SAE vent port can be directly connected to a pilot switching valve with minimal leakage requirements, making it ideal for integration with Sun's DAA solenoid pilot valve. Ports 1 and 2 are fully sealed from port 3, accommodating pressures up to the maximum operating limit of 5000 psi (350 bar). The valve incorporates Sun's floating style construction to minimize internal binding due to installation torque or machining variations. The DOHDEHV fits into a T-17A cavity and belongs to Series 3, offering a capacity of up to 60 gpm (240 L/min). It requires a minimum pilot pressure of 300 psi (20 bar) to shift the valve effectively. For installation, it has a hex size of 1-1/4 inches (31.8 mm) and should be torqued between 150-160 lbf ft (203-217 Nm). The Viton seal kit for this cartridge is identified by part number: 990017006.

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).
- 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 open when the pilot pressure falls below 145 psi (10 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.
- 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.
