The Sun Hydraulics DOHPLBV (DOHPLBV) is a normally open, balanced poppet switching element designed to provide predictable switching performance under high-pressure conditions. This valve operates with a maximum operating pressure of 5000 psi (350 bar) at both port 1 and port 2, making it suitable for demanding hydraulic applications. The valve remains open until the pilot pressure applied to port 3 reaches the setting established by the integral pilot relief stage, at which point it shifts to a closed position. The unique balanced construction ensures that any backpressure at the drain port is directly additive to the valve setting. The DOHPLBV features a low leakage rate between ports 1 and 2, typically less than 10 drops per minute at 5000 psi (0.7 cc/min at 350 bar), ensuring efficient operation with minimal fluid loss. It incorporates Sun's floating style construction to minimize internal part binding due to excessive installation torque or cavity/cartridge machining variations. The valve requires a minimum pilot pressure of 300 psi (20 bar) to shift and will open when pilot pressure falls below 145 psi (10 bar). All ports can handle pressures up to 5000 psi (350 bar), and ports are fully sealed from each other, ensuring reliable isolation. This hydraulic component is ideal for applications requiring precise control under high-pressure conditions and can handle flow capacities of up to 60 gpm (240 L/min). Installation requires specific torque values for optimal performance: valve installation torque ranges from 150 - 160 lbf ft (203 - 217 Nm), with an adjustment screw internal hex size of 5/32 in. (4 mm) and locknut torque between 80 - 90 lbf in. (9 -10 Nm).

This is a normally open, balanced poppet, switching element. When pilot pressure is applied to port 3, the poppet remains open until the pilot pressure reaches the setting established by the integral pilot relief stage, at which point the poppet shifts to the closed position.
- Unique balanced construction provides predictable switching with 5000 psi (350 bar) at both port 1 and port 2. When the remote pressure signal at port 3 exceeds the internal valve setting, the valve shifts to the closed position.
- Any backpressure at the drain port is directly additive to the valve setting.
- Valve will open when the pilot pressure falls below 145 psi (10 bar).
- These valves are hydraulically balanced between port 1 and port 2.
- Port 1 and port 2 are fully sealed from port 3 and port 4. Ports 3 and 4 are positively sealed.
- 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).
- 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.
