The Sun Hydraulics DKDPCAV (DKDPCAV) is a high-performance hydraulic valve designed for precise control in fluid power systems. This normally closed, balanced poppet switching element operates effectively with a maximum operating pressure of 5000 psi (350 bar), suitable for demanding applications. The valve features unique balanced construction that ensures predictable switching behavior and performance under varying conditions. The DKDPCAV valve is engineered to shift from a closed to an open position when pilot pressure applied at port 3 surpasses the preset internal valve setting determined by its integral pilot relief stage. This mechanism allows for controlled operation and maintains system stability by preventing unexpected pressure spikes or drops. Notably, any backpressure at the drain port influences the valve setting directly, adding to its operational precision. Designed with robustness in mind, the DKDPCAV incorporates Sun's floating style construction which minimizes potential internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This feature enhances the durability and reliability of the valve in various installation environments. The hydraulic valve also boasts minimal leakage between ports 1 and 2, typically less than 10 drops per minute at 5000 psi, ensuring efficient system performance with reduced fluid loss. It supports a flow capacity of up to 15 gpm (60 L/min), making it versatile for a range of medium to high-flow applications. The required minimum pilot pressure to shift the valve is 400 psi (28 bar), providing flexibility in control settings according to system requirements. Overall, the Sun Hydraulics DKDPCAV valve is an essential component for systems requiring reliable and precise fluid control under high-pressure conditions, suitable for various industrial hydraulic applications.

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.
