The Sun Hydraulics DKDPCCN (DKDPCCN) is a highly engineered hydraulic valve designed for precise control in fluid power applications. This model features a normally closed, balanced poppet switching element that operates efficiently under high-pressure conditions up to 5000 psi (350 bar). The valve maintains low leakage rates, typically less than 10 drops per minute at maximum pressure, ensuring effective fluid management and minimizing wastage. A key feature of the DKDPCCN is its unique balanced construction which allows for predictable switching between ports. It incorporates an integral pilot relief stage which dictates the pilot pressure required to shift the valve; this valve will shift to an open position once the pilot pressure at port 3 surpasses a pre-set value. Additionally, any backpressure at the drain port directly adds to the valve setting, enhancing its functionality under various operating conditions. Designed with robustness in mind, the DKDPCCN uses Sun's floating style construction to reduce risks of internal parts binding which can occur due to excessive installation torque or cavity/cartridge machining variations. It supports a flow capacity of up to 15 gpm (60 L/min) and can handle a maximum operating pressure of 5000 psi (350 bar). For maintenance and adjustments, it features accessible internal and locknut hex sizes for easy handling. This model is specifically advantageous in systems requiring reliable performance where precise hydraulic control is critical. Its construction ensures that ports are effectively sealed against leaks and cross-port contamination, making it suitable for complex hydraulic circuits demanding high reliability and efficiency.

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.
