The Sun Hydraulics DODDEHV (Material Number: DODDEHV) is a normally open, balanced poppet switching element designed to provide reliable hydraulic control in high-pressure applications. This valve remains open when the external vent port is blocked and closes upon venting the external port, provided there is sufficient pressure at port 3. Featuring a unique balanced construction, it ensures predictable switching with pressures up to 5000 psi (350 bar) at both ports 1 and 2 when the external drain is open and requires a minimum pilot pressure of 400 psi (30 bar). The valve's design includes an external 4 SAE vent port that can be directly connected to a pilot switching valve with minimal leakage, making it ideal for use with the Sun model DAA solenoid pilot valve. Hydraulically balanced between ports 1 and 2, the DODDEHV exhibits a low leakage rate of less than 10 drops/min at 5000 psi (0.7 cc/min at 350 bar). It opens when pilot pressure falls below 145 psi (10 bar), ensuring reliable operation under varying conditions. All ports are capable of handling pressures up to 5000 psi (350 bar) and are fully sealed from port 3, enhancing operational integrity. The valve incorporates Sun's floating style construction, which minimizes the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. It fits into T11A cavities and belongs to Series 1 with a capacity of up to 15 gpm (60 L/min). Installation requires a torque range of 30-35 lbf ft (41-47 Nm), and it uses Viton seal kits for optimal performance. This robust design makes it suitable for various hydraulic systems requiring precise control and reliability under high-pressure 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.
