The Sun Hydraulics DOJCXHV (DOJCXHV) is a normally open, balanced poppet switching element designed for high-pressure hydraulic applications. This valve features a unique balanced construction that ensures predictable switching at 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 the valve to the closed position. The valve is engineered for minimal leakage, typically less than 10 drops per minute at maximum pressure, making it highly efficient for controlling hydraulic flow. This three-port balanced logic valve can be used as a functional replacement for unbalanced valves of the same frame size, offering versatility in various hydraulic systems. It is available in external atmospheric vent (X control) or static external drain (E control) configurations, providing flexibility based on specific circuit requirements. The X control version is atmospherically referenced and ideal for solving issues in existing circuits using non-vented valves, though it may eventually leak externally or allow moisture ingress into the spring chamber over time. For new applications, four-port valves are recommended. The DOJCXHV model incorporates Sun's floating style construction to minimize binding due to excessive installation torque or machining variations in cavity/cartridge designs. This hydraulically balanced valve between port 1 and port 2 ensures reliable performance across a range of conditions while maintaining full sealing from port 3. With a capacity of up to 120 gpm (480 L/min), this valve is suitable for high-flow applications requiring robust and stable hydraulic control solutions.

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 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.
- Valve will open when the pilot pressure falls below 145 psi (10 bar).
- 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.
