The Sun Hydraulics DODPLWN (DODPLWN) is a normally open, balanced poppet switching element designed for precise hydraulic control. This component operates by maintaining an open position when pilot pressure is applied to port 3 until the pressure reaches a specified setting determined by the integral pilot relief stage, at which point it shifts to a closed position. The unique balanced construction ensures predictable switching at pressures up to 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 transitions to its closed state. Any backpressure at the drain port adds directly to the valve's setting, and it will reopen when pilot pressure drops below 145 psi (10 bar). The hydraulic balance between ports 1 and 2, along with full sealing from ports 3 and 4, minimizes leakage between ports\u2014typically less than 10 drops per minute at maximum pressure. This valve incorporates Sun's floating style construction, reducing potential binding issues due to installation torque or machining variations. The DODPLWN fits in cavity T-21A and belongs to series 1 with a capacity of up to 15 gpm (60 L/min). It requires a minimum pilot pressure of 400 psi (28 bar) for shifting and can handle a maximum operating pressure of 5000 psi (350 bar). The cartridge features Viton seals and specific installation requirements including a valve hex size of 7/8 inch (22.2 mm) and installation torque between 30-35 lbf ft (41-47 Nm). This robust design makes it suitable for applications requiring reliable switching under high-pressure conditions while minimizing leakage and ensuring long-term durability.

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.
