The Sun Hydraulics DKDPCDV (DKDPCDV) is a high-performance hydraulic valve designed for precise control in fluid power applications. This normally closed, balanced poppet valve operates as a switching element with a unique construction that ensures predictable switching and high durability. The valve features an integral pilot relief stage that allows the poppet to shift to the open position only when the pilot pressure at port 3 reaches a pre-set level. The DKDPCDV is capable of handling pressures up to 5000 psi (350 bar) at both port 1 and port 2, which are fully sealed from ports 3 and 4. The leakage rate between ports 1 and 2 is exceptionally low, typically less than 10 drops per minute at maximum pressure, ensuring efficient operation with minimal fluid loss. Additionally, any backpressure at the drain port directly adds to the valve setting, enhancing its performance stability under varying conditions. Constructed with Sun\u2019s floating style design, the DKDPCDV minimizes potential internal part binding caused by excessive installation torque or variations in cavity/cartridge machining. This feature contributes to its robustness and reliability in demanding applications. The valve supports a flow capacity of up to 15 gpm (60 L/min) and requires a minimum pilot pressure of 400 psi (28 bar) to shift, making it suitable for a wide range of hydraulic systems where precise flow control is crucial. With its advanced design and high-quality construction, the Sun Hydraulics DKDPCDV valve is an essential component for systems requiring accurate control of high-pressure fluids in various operational conditions.

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.
