The Sun Hydraulics DOFCXHV (DOFCXHV) is a normally open, balanced poppet switching element designed for high-pressure hydraulic systems. It shifts to the closed position when pilot pressure is applied at port 3. Its unique balanced construction allows for predictable switching at pressures up to 5000 psi (350 bar) across ports 1 and 2, with an external drain open and requiring a minimum pilot pressure of 300 psi (20 bar). The valve exhibits a very low leakage rate between ports 1 and 2, typically less than 10 drops per minute at 5000 psi. It is hydraulically balanced between these ports and will open when pilot pressure falls below 145 psi (10 bar). This model can be used as a functional replacement for unbalanced logic valves of the same frame size, fitting into the same cavity T2A. It offers configurations in external atmospheric vent X control or static external drain E control. The three-port vented logic elements with X control are atmospherically referenced, ideal for solving issues in circuits using non-vented valves. Over time, these valves may leak externally or allow moisture into the spring chamber; hence, four-port valves are recommended for new applications. The valve's design incorporates Sun's floating style construction to minimize binding due to excessive installation torque or machining variations. With a capacity of 30 gpm (120 L/min), it accepts up to 5000 psi (350 bar) across all ports and requires proper installation torque between 45 - 50 lbf ft (61 - 68 Nm). Additionally, the valve features a Viton seal kit option for enhanced durability and performance under various conditions.

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.
