The Sun Hydraulics DKFCEHN (DKFCEHN) is a high-performance hydraulic valve designed for precise fluid control in various applications. This normally closed, balanced poppet switching element operates efficiently with pilot pressure at port 3, which shifts the valve to the open position when required. The DKFCEHN boasts a unique balanced construction that ensures predictable switching, supporting pressures up to 5000 psi (350 bar) at both ports 1 and 2 with an external drain open. It requires a minimum pilot pressure of 300 psi (20 bar) to shift and will reseat when the pilot pressure falls below 145 psi (10 bar). The valve features very low leakage rates between port 1 and port 2, typically less than 10 drops per minute at maximum operating pressure, enhancing system efficiency and reducing fluid loss. Designed for versatility, it uses the same cavity as unbalanced logic valves of the same frame size, making it a functional replacement for those units. The DKFCEHN is available in different configurations: external atmospheric vent (X control) or static external drain (E control), providing solutions based on specific circuit needs. Additionally, this model incorporates Sun\u2019s floating style construction which minimizes internal parts binding\u2014a common issue due to excessive installation torque or cavity/cartridge machining variations. This feature ensures reliable operation and longevity of the valve in demanding environments. With its robust design and advanced hydraulic capabilities, the Sun Hydraulics DKFCEHN is an ideal choice for optimizing hydraulic system performance across various applications.

This is a normally closed, balanced poppet, switching element. Pilot pressure at port 3 shifts the valve to the open position.

  • Unique balanced construction provides predictable switching with 5000 psi (350 bar) at both ports 1 and 2, with the external drain open and a minimum pilot pressure of 300 psi (20 bar).
  • 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).
  • Valve will reseat when the pilot pressure falls below 145 psi (10 bar).
  • These 3-port balanced logic valves use the same cavity as unbalanced logic valves of the same frame size and can be considered functional replacements.
  • Available in external atmospheric vent (X control) or static external drain (E control) configurations.
  • Three-port vented logic elements with the X control are atmospherically referenced and considered problem solvers for existing circuits using non-vented valves. Over time, these valves will eventually leak externally and/or allow moisture into the spring chamber. Four-port valves are recommended for new applications. Alternately, the external vent port can be connected to drain if the static drain port option (control option E) is selected. Removing the vent plug will convert an X control to an E control.
  • These valves are hydraulically balanced between port 1 and port 2.
  • Port 1 and port 2 are fully sealed from port 3.
  • 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.
