The Sun Hydraulics DOJPLDV (DOJPLDV) is a normally open, balanced poppet switching element designed for precise hydraulic control. This component operates by maintaining an open poppet until the pilot pressure at port 3 reaches a pre-set level determined by the integral pilot relief stage, causing the poppet to close. Its unique balanced construction allows for reliable switching at pressures up to 5000 psi (350 bar) at both port 1 and port 2. The valve is engineered to handle high-pressure applications, with all ports capable of accepting up to 5000 psi (350 bar). It features a low leakage rate between port 1 and port 2, typically less than 10 drops per minute at full pressure. The DOJPLDV valve is hydraulically balanced between ports 1 and 2, ensuring that these ports are completely sealed from ports 3 and 4, which are also positively sealed. Any backpressure at the drain port directly adds to the valve setting. The valve opens when pilot pressure drops below 145 psi (10 bar), requiring a minimum pilot pressure of 300 psi (20 bar) to shift. With a capacity of up to 120 gpm (480 L/min), this component is suitable for high-flow applications. The design incorporates Sun's floating style construction to reduce the risk of internal binding due to installation torque or machining variations in cavities or cartridges. The valve's hex size is 1-5/8 inches (41.3 mm), and it requires an installation torque between 350 and 375 lbf-ft (475 -508 Nm). Additional specifications include an adjustment screw internal hex size of 5/32 inches (4 mm) and a locknut hex size of 9/16 inches (15 mm), with locknut torque ranging from 80 to 90 lbf-in (9 -10 Nm). A Viton seal kit is available for this cartridge model under part number: Viton:990024006.

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.
- 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).
- Valve will open when the pilot pressure falls below 145 psi (10 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.
