The Sun Hydraulics DOFCXHN (DOFCXHN) is a normally open, balanced poppet, switching element designed for hydraulic applications requiring precise control and minimal leakage. This valve shifts to a closed position when pilot pressure is applied at port 3. It boasts a unique balanced construction, allowing predictable switching capabilities with pressures up to 5000 psi (350 bar) at ports 1 and 2, provided the external drain is open and a minimum pilot pressure of 300 psi (20 bar) is maintained. The leakage rate between ports 1 and 2 is impressively low, typically less than 10 drops per minute at maximum pressure. The DOFCXHN valve features hydraulic balancing between its ports, ensuring reliable performance even under high-pressure conditions. It will automatically open when the pilot pressure drops below 145 psi (10 bar). This model can be configured with either an external atmospheric vent (X control) or a static external drain (E control), making it versatile for different circuit requirements. The three-port vented logic elements with X control are particularly effective in solving issues in existing circuits that use non-vented valves. The valve's design includes Sun's floating style construction, which minimizes the risk of internal part binding due to excessive installation torque or variations in cavity/cartridge machining. With a capacity of up to 30 gpm (120 L/min), this valve fits into the T2A cavity series and requires an installation torque between 45-50 lbf ft (61-68 Nm). The DOFCXHN is robust enough to handle maximum operating pressures while maintaining low leakage levels, making it suitable for demanding hydraulic systems that require efficient and reliable switching elements.

This is a normally open, balanced poppet, switching element. Pilot pressure at port 3 shifts the valve to the closed 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).
- These valves are hydraulically balanced between port 1 and port 2.
- Valve will open 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.
- 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.
