The Sun Hydraulics DOJCEHV (DOJCEHV) is a normally open, balanced poppet switching element designed for efficient hydraulic control. This valve shifts to a closed position when pilot pressure is applied at port 3, offering predictable switching capabilities with pressures up to 5000 psi (350 bar) at both ports 1 and 2. It requires a minimum pilot pressure of 300 psi (20 bar) to operate effectively. Featuring an external drain option, the valve provides a very low leakage rate between port 1 and port 2, typically less than 10 drops per minute at maximum pressure. The DOJCEHV can serve as a functional replacement for unbalanced logic valves of the same frame size and fits within the T19A cavity. This valve is available in two configurations: external atmospheric vent (X control) or static external drain (E control). The X control configuration is atmospherically referenced, making it ideal for solving problems in existing circuits that use non-vented valves. However, over time, these may leak externally or allow moisture into the spring chamber; thus, four-port valves are recommended for new applications. Alternatively, connecting the external vent port to drain when using the E control option can mitigate these issues. The DOJCEHV incorporates Sun's floating style construction to reduce internal binding risks due to excessive installation torque or machining variations. It features a capacity of 120 gpm (480 L/min), with all ports capable of handling up to 5000 psi (350 bar). The valve will open when pilot pressure drops below 145 psi (10 bar), ensuring reliable operation across various applications where hydraulic balance between ports is crucial.

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.
