The Sun Hydraulics DKDPKCN (DKDPKCN) is a high-performance hydraulic valve designed for precise fluid control in various applications. This model features a normally closed, balanced poppet switching element that operates under a unique mechanism where the poppet remains closed until pilot pressure at port 3 reaches a predefined threshold set by an integral pilot relief stage, subsequently shifting to an open position. This allows for predictable switching and efficient operation under high-pressure conditions up to 5000 psi (350 bar) at both port 1 and port 2. The DKDPKCN valve is engineered to handle backpressure at the drain port, which is additive to the valve setting, ensuring robust performance in complex hydraulic systems. It reseats when the pilot pressure falls to 85% of the cracking value, providing a reliable return to a closed state. The leakage between ports 1 and 2 is minimal, typically less than 10 drops per minute at maximum pressure, highlighting its efficiency in maintaining system integrity. Constructed with Sun\u2019s floating style design, the DKDPKCN minimizes internal part binding that could result from excessive installation torque or variations in cavity/cartridge machining. This feature ensures long-term durability and consistent performance. The valve is housed within a T21A cavity and belongs to Series 1. It supports up to 15 gpm (60 L/min) capacity and requires a minimum pilot pressure of 400 psi (28 bar) to shift effectively. Key specifications include a maximum operating pressure of 5000 psi (350 bar), control pilot flow as per performance data, and an adjustment screw internal hex size of 5/32 inches (4 mm). The seal kit for this cartridge uses Viton material (990021006), ensuring excellent resistance against high temperatures and chemical degradation.

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.
