The Sun Hydraulics DKDPLCN (DKDPLCN) is a high-performance hydraulic switching element designed for robust and precise fluid control in various applications. This model is a normally closed, balanced poppet valve that operates under a unique mechanism where the poppet remains closed until pilot pressure at port 3 reaches a pre-set threshold determined by an integral pilot relief stage. Upon reaching this setting, the valve shifts to an open position, allowing for controlled fluid flow. The DKDPLCN supports impressive operational parameters with both port 1 and port 2 capable of handling up to 5000 psi or 350 bar. It features a low leakage rate between these ports, typically less than 10 drops per minute at maximum pressure, ensuring efficient system performance with minimal fluid loss. The construction of the valve incorporates Sun\u2019s floating style design which minimizes internal part misalignment and potential binding issues that could arise from excessive installation torque or variations in cavity/cartridge machining. This valve is engineered to reseat when pilot pressure decreases to 85% of the cracking value, enhancing its reliability and operational lifespan. All ports on the DKDPLCN are rated to accept pressures up to 5000 psi or 350 bar, making it suitable for high-pressure applications across various hydraulic systems. Additionally, any backpressure at the drain port directly adds to the valve setting, providing further versatility in application configurations. Designed for ease of maintenance and installation, the DKDPLCN features standardized hex sizes for the valve and adjustment screws, promoting straightforward assembly and adjustments in field conditions. This model is particularly suited for systems requiring precise control over fluid handling and pressure management, offering both reliability and high performance in demanding environments.

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.
