The Sun Hydraulics DODCEHV (DODCEHV) is a normally open, balanced poppet switching element designed for reliable hydraulic applications. This valve utilizes pilot pressure at port 3 to shift to a closed position, offering predictable switching performance even under high pressure conditions of up to 5000 psi (350 bar) at both ports 1 and 2. It requires a minimum pilot pressure of 400 psi (28 bar) to function, and will automatically open when the pilot pressure drops below 145 psi (10 bar). The valve is hydraulically balanced between ports 1 and 2, minimizing leakage rates to less than 10 drops per minute at maximum pressure, making it highly efficient and reliable. The DODCEHV model features external atmospheric vent X control or static external drain E control configurations. Its unique balanced construction allows it to serve as a functional replacement for unbalanced logic valves of the same frame size. The three-port vented logic elements with X control are particularly useful in existing circuits that use non-vented valves, although four-port valves are recommended for new applications due to potential long-term leakage issues. This model incorporates Sun's floating style construction, which reduces the risk of internal part binding due to excessive installation torque or variations in cavity/cartridge machining. It fits into a T-11A cavity and has a flow capacity of up to 15 gpm (60 L/min). The valve's compact design includes a hex size of 7/8 inches (22.2 mm), weighs .35 lb (.15 kg), and requires an installation torque between 30-35 lbf ft (41-47 Nm). For maintenance, Viton seal kits are available under part number 990311006.

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 400 psi (30 bar).
- Valve will open when the pilot pressure falls below 145 psi (10 bar).
- These valves are hydraulically balanced between port 1 and port 2.
- 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.
- 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.
