The Sun Hydraulics DOHPLAV (Material Number: DOHPLAV) is a normally open, balanced poppet switching element designed for high-pressure hydraulic systems. This component utilizes unique balanced construction to provide predictable switching performance at pressures up to 5000 psi (350 bar) between port 1 and port 2. The valve remains open under pilot pressure applied to port 3 until the pressure reaches the setting established by the integral pilot relief stage, prompting the poppet to shift to a closed position. Importantly, any backpressure at the drain port directly influences the valve setting. The valve reopens when pilot pressure falls below 145 psi (10 bar). The DOHPLAV features hydraulic balancing between ports 1 and 2, ensuring they are fully sealed from ports 3 and 4, which are also positively sealed. This design results in a very low leakage rate between ports 1 and 2, typically less than 10 drops per minute at maximum operating pressure. All ports can accommodate pressures up to 5000 psi (350 bar). The valve incorporates Sun's floating style construction, which minimizes internal binding risks due to installation torque or machining variations. The DOHPLAV fits into cavity T-23A and belongs to Series 3 with a capacity of up to 60 gpm (240 L/min). It requires a minimum pilot pressure of 300 psi (20 bar) for actuation. The valve's hex size is 1-1/4 inches (31.8 mm), with an installation torque specification of 150-160 lbf ft (203-217 Nm). It includes an adjustment screw with an internal hex size of 5/32 inches (4 mm) and a locknut hex size of 9/16 inches (15 mm), torqued at 80-90 lbf in (9-10 Nm). A Viton seal kit is available for maintenance needs.

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.
