The Sun Hydraulics DOJPLBN (DOJPLBN) is a normally open, balanced poppet switching element designed for precise hydraulic control. This component features a unique balanced construction that ensures predictable switching at pressures up to 5000 psi (350 bar) at both port 1 and port 2. The valve operates by remaining open until the pilot pressure applied to port 3 reaches a pre-set level, triggering the poppet to close. It is engineered with hydraulic balance between ports 1 and 2, while ports 3 and 4 are sealed off from these primary ports. The valve's leakage rate is exceptionally low, typically less than 10 drops per minute at maximum pressure. It incorporates Sun Hydraulics' floating style construction to reduce the risk of internal part binding due to installation torque or machining variations. With a capacity of up to 120 gpm (480 L/min), this valve requires a minimum pilot pressure of 300 psi (20 bar) to shift and can handle backpressure directly additive to its setting. The design includes features like an internal adjustment screw for fine-tuning and Viton seal compatibility through an available seal kit. This robust component is suitable for applications requiring reliable switching under high-pressure conditions and offers ease of installation with specified torque settings for both the valve body and locknut components.

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.
