The Sun Hydraulics DODDEHN (DODDEHN) is a normally open, balanced poppet switching element designed for precise hydraulic control. This valve remains open when the external vent port is blocked and shifts to a closed position when the external port is vented, assuming there is adequate pressure at port 3. Its unique balanced construction allows for predictable switching even under high pressure conditions of up to 5000 psi (350 bar) at both ports 1 and 2. The valve requires a minimum pilot pressure of 400 psi (28 bar) to shift, and features an external SAE vent port that can be directly connected to a pilot switching valve with minimal leakage. The DODDEHN model is hydraulically balanced between ports 1 and 2, ensuring very low leakage rates\u2014typically less than 10 drops per minute at maximum pressure. It will open when pilot pressure falls below 145 psi (10 bar), with ports fully sealed from one another to maintain integrity under high-pressure conditions. The valve supports a flow capacity of up to 15 gpm (60 L/min) and incorporates Sun's floating style construction, minimizing internal binding risks due to installation torque or machining variations. With its T11A cavity design and robust performance characteristics, this valve is ideal for applications requiring reliable hydraulic switching under demanding conditions.

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 both ports 1 and 2, with the external drain open and a minimum pilot pressure of 400 psi (30 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 open 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.
