The Sun Hydraulics DKFPLAV (DKFPLAV) is a high-performance hydraulic valve designed for precision control in fluid power applications. This normally closed, balanced poppet, switching element operates efficiently under a maximum operating pressure of 5000 psi (350 bar). The valve features a unique balanced construction that ensures predictable switching between ports. It is equipped with an integral pilot relief stage that allows the poppet to open only when the pilot pressure at port 3 surpasses a pre-set threshold. The DKFPLAV supports up to 30 gpm (120 L/min) flow capacity and requires a minimum pilot pressure of 300 psi (20 bar) to shift the valve. It is designed to minimize leakage, with rates typically less than 10 drops/min at 5000 psi or 0.7 cc/min at 350 bar between port 1 and port 2. The design incorporates Sun\u2019s floating style construction which reduces the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This valve's robust construction includes Viton seals for enhanced durability and chemical resistance. All ports on the DKFPLAV can withstand pressures up to 5000 psi (350 bar), and any backpressure at the drain port directly adds to the valve setting, enhancing its operational flexibility. The valve will reseat when pilot pressure falls to approximately 85% of the cracking value, ensuring reliable operation and preventing unintended shifts in flow direction. This makes the DKFPLAV an ideal choice for applications requiring precise control over high-pressure fluid handling and distribution systems.

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.
