The Sun Hydraulics DKJPLBV (DKJPLBV) is a high-performance hydraulic valve characterized by its normally closed, balanced poppet, switching element design. This model operates effectively under a maximum pressure of 5000 psi (350 bar) and can handle up to 120 gpm (480 L/min). The valve features unique balanced construction that ensures predictable switching between ports. It remains closed until pilot pressure applied to port 3 reaches the pre-set relief stage, subsequently shifting to an open position to allow fluid flow. The DKJPLBV is designed with an integral pilot relief stage that allows the poppet to open only when the pilot pressure exceeds the set value, providing precise control over hydraulic flow. It also features very low leakage rates between port 1 and port 2, typically less than 10 drops/min at 5000 psi. Each port in this model can withstand pressures up to 5000 psi, which makes it suitable for various demanding applications. In terms of construction, the valve incorporates Sun's floating style which minimizes potential internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. This ensures reliable operation and longevity of the valve even under strenuous conditions. The minimum pilot pressure required to shift the valve is 300 psi (20 bar), allowing for flexible application across different hydraulic systems. For installation, this model requires a torque of 350 - 375 lbf ft (474 - 508 Nm) and comes with a seal kit featuring Viton components for enhanced durability against harsh fluids and environments. Overall, the Sun Hydraulics DKJPLBV offers robust performance and reliability for industrial hydraulic systems requiring precise flow control and high-pressure capability.

This is a normally closed, balanced poppet, switching element. When pilot pressure is applied to port 3, the poppet remains closed until the pilot pressure reaches the setting established by the integral pilot relief stage, at which point the poppet shifts to the open 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 open position.
- Any backpressure at the drain port is directly additive to the valve setting.
- Valve will reseat when the pilot pressure falls to 85% of the cracking value.
- 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.
