The Sun Hydraulics DKDPKCV (DKDPKCV) is a high-performance hydraulic valve designed for precise fluid control in advanced hydraulic systems. This model features a normally closed, balanced poppet switching element that operates under a pilot pressure mechanism. The valve remains closed until the pilot pressure at port 3 reaches a pre-set threshold determined by an integral pilot relief stage, which then causes the poppet to shift to an open position, allowing fluid flow. Engineered for durability and reliability, the DKDPKCV can handle up to 5000 psi (350 bar) at ports 1 and 2, ensuring robust performance even under high-pressure conditions. It incorporates Sun's unique floating style construction which minimizes potential internal binding caused by excessive installation torque or cavity/cartridge machining variations. This design enhancement contributes to the valve\u2019s operational stability and longevity. The valve also features a low leakage rate between port 1 and port 2, typically less than 10 drops/min at 5000 psi (0.7 cc/min at 350 bar), which is crucial for maintaining system efficiency and preventing fluid loss. Additionally, any backpressure at the drain port directly adds to the valve setting, enhancing control accuracy. Designed with multiple sealing points, ports 1 and 2 are fully isolated from ports 3 and 4, which are positively sealed against external contaminants. The DKDPKCV supports a maximum flow capacity of 15 gpm (60 L/min) and requires a minimum pilot pressure of 400 psi (28 bar) to shift the valve. This model is suited for various hydraulic applications where precise fluid control and high-pressure capabilities are necessary.

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.
