The Sun Hydraulics DKFPLBN (DKFPLBN) is a high-performance, normally closed, balanced poppet switching element designed for hydraulic systems requiring reliable control and switching capabilities under high pressure. This model operates effectively with a maximum operating pressure of 5000 psi (350 bar), ensuring robust performance in demanding applications. The valve features a unique balanced construction that allows for predictable switching between ports, maintaining low leakage rates typically less than 10 drops/min at 5000 psi. Equipped with an integral pilot relief stage, the DKFPLBN only shifts to an open position when the pilot pressure at port 3 exceeds the pre-set valve threshold, enhancing operational safety and precision. This setup also includes a reseating feature where the valve returns to its closed position once the pilot pressure drops to 85% of the cracking value. Each port in this model is designed to withstand pressures up to 5000 psi, and backpressure at the drain port directly adds to the valve setting, offering further versatility in application. The DKFPLBN incorporates Sun\u2019s floating style construction which minimizes potential internal part binding caused by excessive installation torque or cavity/cartridge machining variations. This ensures prolonged operational life and reduced maintenance needs. It is suitable for systems with a flow capacity up to 30 gpm (120 L/min) and requires a minimum pilot pressure of 300 psi (20 bar) to shift the valve, making it ideal for various hydraulic applications where high-pressure control is crucial.

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.
