The Sun Hydraulics DOFPLAN (DOFPLAN) is a normally open, balanced poppet switching element designed for precise hydraulic control. It features a unique balanced construction, allowing for predictable switching at pressures up to 5000 psi (350 bar) at both port 1 and port 2. When the pilot pressure at port 3 exceeds the internal valve setting, the poppet shifts to a closed position. The valve will reopen when pilot pressure falls below 145 psi (10 bar). This component is hydraulically balanced between ports 1 and 2, ensuring minimal leakage, typically less than 10 drops per minute at maximum pressure. The DOFPLAN utilizes Sun's floating style construction to reduce the risk of internal part binding due to installation torque or machining variations. The valve operates within a cavity size of T22A and belongs to series 2 with a capacity of up to 30 gpm (120 L/min). It requires a minimum pilot pressure of 300 psi (20 bar) to shift and can handle maximum operating pressures of up to 5000 psi (350 bar). Installation requires specific torque settings for both the valve hex size and locknut, with detailed specifications provided for proper assembly. The design ensures that all ports can withstand high pressures while maintaining positive seals between ports 3 and 4. Additionally, any backpressure at the drain port adds directly to the valve setting, offering reliable performance in various hydraulic applications where precise control is essential.

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.
