The Sun Hydraulics DOHPLAN (DOHPLAN) is a normally open, balanced poppet switching element designed for high-performance hydraulic systems. This component features a unique balanced construction, ensuring predictable switching capabilities with an operating pressure of up to 5000 psi (350 bar) at both port 1 and port 2. When pilot pressure is applied to port 3, the poppet remains open until the pressure reaches the pre-set level determined by the integral pilot relief stage, at which point it shifts to a closed position. The valve will reopen when pilot pressure drops below 145 psi (10 bar). The DOHPLAN's design includes full hydraulic balancing between ports 1 and 2, while ports 3 and 4 are positively sealed from each other and from ports 1 and 2. The leakage rate between ports is minimal, typically less than 10 drops per minute at maximum pressure, enhancing efficiency in hydraulic circuits. It can handle a flow capacity of up to 60 gpm (240 L/min), making it suitable for demanding applications. This valve incorporates Sun Hydraulics' floating style construction to reduce the risk of internal binding due to excessive installation torque or machining variations in cavity or cartridge. It fits into a T-23A cavity and requires an installation torque of 150 - 160 lbf ft (203 - 217 Nm). Additionally, it features an internal hex adjustment screw size of 5/32 inches (4 mm) and a locknut hex size of 9/16 inches (15 mm), with a locknut torque specification of 80 - 90 lbf in (9 -10 Nm). Overall, the DOHPLAN valve provides reliable performance for controlling fluid flow in complex hydraulic systems where precise switching is critical.

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.
