The Sun Hydraulics DKFPLWN (DKFPLWN) is a highly advanced hydraulic valve designed for precise control in fluid power applications. This model features a normally closed, balanced poppet switching element that operates based on pilot pressure applied to port 3. The valve maintains closure until the pilot pressure exceeds a preset threshold determined by an integral pilot relief stage, at which point it shifts to an open position for fluid passage. Engineered to handle high pressures up to 5000 psi (350 bar) at both port 1 and port 2, the DKFPLWN ensures reliable performance and robust operation under demanding conditions. It includes unique features such as a leakage rate of less than 10 drops per minute at maximum pressure, showcasing its efficiency and minimal fluid loss. The construction of the valve incorporates Sun's floating style design which minimizes internal part binding and potential malfunctions due to installation torque or machining variations in the cavity or cartridge. This valve also boasts comprehensive sealing between ports; ports 1 and 2 are fully isolated from ports 3 and 4, ensuring no cross-contamination or leakage between these interfaces. Additionally, any backpressure at the drain port directly adds to the valve setting, enhancing its responsiveness and operational accuracy. Upon reduction of pilot pressure to approximately 85% of the cracking value, the valve will reseat itself, securing the system once more. The DKFPLWN is encased within a T22A cavity with a series-2 classification and can support up to 30 gpm (120 L/min) flow capacity. It requires a minimum pilot pressure of 300 psi (20 bar) to shift the valve, making it suitable for various medium to high-pressure applications across different hydraulic systems. This model's adaptability and precision control make it a critical component for efficient hydraulic operations.

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.
