The Sun Hydraulics DOHPLWN (DOHPLWN) is a normally open, balanced poppet switching element designed for high-pressure hydraulic systems. This component features a unique balanced construction that ensures predictable switching performance with pressures up to 5000 psi (350 bar) at both port 1 and port 2. The valve remains open when pilot pressure is applied to port 3, and only shifts to the closed position once the pilot pressure surpasses the setting established by the integral pilot relief stage. A noteworthy aspect of this valve is its hydraulic balance between port 1 and port 2, along with full sealing from ports 3 and 4, ensuring minimal leakage\u2014typically less than 10 drops per minute at maximum pressure. The DOHPLWN valve incorporates Sun's floating style construction, which minimizes internal binding due to excessive installation torque or cavity/cartridge machining variations. It requires a minimum pilot pressure of 300 psi (20 bar) to shift the valve and can handle a maximum operating pressure of up to 5000 psi (350 bar). The valve's capacity is rated at 60 gpm (240 L/min), making it suitable for applications requiring high flow rates. Additional specifications include a cavity size of T-23A, series number 3, and various installation torque requirements such as a valve hex size of 1-1/4 inches (31.8 mm) with an installation torque range of 150\u2013160 lbf ft (203\u2013217 Nm). For adjustments, it features an internal hex size adjustment screw measuring 5/32 inches (4 mm) and a locknut hex size of 9/16 inches (15 mm), with locknut torque specified between 80\u201390 lbf in. (9\u201310 Nm). The valve also uses Viton seals for enhanced durability in demanding environments.

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.
