The Sun Hydraulics DKJPLDN (DKJPLDN) is a high-performance hydraulic valve designed for robust and efficient control in hydraulic systems. This normally closed, balanced poppet switching element operates effectively with a maximum operating pressure of 5000 psi (350 bar). The valve features an integral pilot relief stage that determines the pilot pressure required to shift the valve, set at a minimum of 300 psi (20 bar). The DKJPLDN ensures predictable switching between ports, maintaining very low leakage rates\u2014less than 10 drops/min at 5000 psi or 0.7 cc/min at 350 bar\u2014between port 1 and port 2. The construction of the DKJPLDN incorporates Sun's floating style, which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This design feature enhances the durability and reliability of the valve under varying operational conditions. Each port on the valve can withstand pressures up to 5000 psi (350 bar), and any backpressure at the drain port directly adds to the valve setting, ensuring consistent performance. The DKJPLDN also boasts a high capacity of up to 120 gpm (480 L/min), making it suitable for applications requiring substantial fluid handling capabilities. The precise control offered by this model is complemented by its robust construction and compatibility with various hydraulic setups, ensuring it meets diverse application needs while maintaining high efficiency and performance stability.

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.
