The Sun Hydraulics DKDPLWV (DKDPLWV) is a high-performance hydraulic valve designed for precise control in fluid power applications. This normally closed, balanced poppet valve operates as a switching element with an integral pilot relief stage that dictates the shifting of the poppet based on pilot pressure at port 3. The valve remains closed until the pilot pressure surpasses a preset threshold, at which point it shifts to an open position, allowing fluid flow between ports. Featuring a unique balanced construction, the DKDPLWV ensures predictable switching and can handle pressures up to 5000 psi (350 bar) at both port 1 and port 2. The design includes Sun's floating style construction which minimizes internal part binding and accommodates variations in installation torque and cartridge machining. This feature enhances the durability and reliability of the valve in demanding operational conditions. The valve is engineered to reseat when pilot pressure decreases to 85% of the cracking value, offering stable performance and preventing unwanted flow. It supports a maximum flow capacity of 15 gpm (60 L/min) and requires a minimum pilot pressure of 400 psi (28 bar) for shifting. All ports on the DKDPLWV are capable of withstanding up to 5000 psi (350 bar), ensuring versatility across various hydraulic systems. Leakage between port 1 and port 2 is exceptionally low, typically less than 10 drops/min at maximum pressure, which translates to efficient operation with minimal fluid loss. The design also ensures that any backpressure at the drain port directly adds to the valve setting, enhancing operational control. Overall, the Sun Hydraulics DKDPLWV valve offers robust performance for hydraulic systems requiring reliable high-pressure operation with precise control over fluid handling and direction.

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.
