The Sun Hydraulics DOHDEHN (DOHDEHN) 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, provided there is adequate pressure at port 3. The unique balanced construction ensures predictable switching at pressures up to 5000 psi (350 bar) at ports 1 and 2, with the external drain port open and requiring a minimum pilot pressure of 300 psi (20 bar). The valve features hydraulic balancing between ports 1 and 2, with an impressively low leakage rate of less than 10 drops per minute at 5000 psi (0.7 cc/min at 350 bar). It opens when pilot pressure falls below 145 psi (10 bar). The external SAE vent port can be directly connected to a pilot switching valve with specific leakage and flow requirements, making the Sun model DAA solenoid pilot valve an ideal match. Ports 1 and 2 are fully sealed from port 3, capable of handling up to 5000 psi (350 bar). The valve incorporates Sun's floating style construction to minimize internal binding due to installation torque or machining variations. With a capacity of up to 60 gpm (240 L/min) and fitting into cavity T-17A in series three, this component is robustly engineered for demanding environments. Additional specifications include a maximum installation torque of 150-160 lbf ft (203-217 Nm), a Viton seal kit option, and a hex size of 1\u00bc inches (31.8 mm).

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.
