The Sun Hydraulics DOFCEHV (DOFCEHV) is a sophisticated, normally open, balanced poppet switching element designed for high-pressure hydraulic systems. This valve is engineered to shift 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. The valve's unique balanced construction ensures minimal leakage between port 1 and port 2, typically less than 10 drops per minute at maximum pressure. It features three-port balanced logic design that can serve as functional replacements for unbalanced logic valves of the same frame size. The DOFCEHV model accommodates an external atmospheric vent or static external drain control configurations. The X control option provides an atmospheric reference that addresses issues in existing circuits using non-vented valves, while the E control option allows the external vent port to be connected to a drain. The valve opens when pilot pressure falls below 145 psi (10 bar), requiring a minimum pilot pressure of 300 psi (20 bar) to shift the valve effectively. This model incorporates Sun's floating style construction, minimizing internal binding risks due to installation torque or machining variations. It fits into T2A cavity series with a capacity of up to 30 gpm (120 L/min). All ports are fully sealed from each other and can handle pressures up to 5000 psi (350 bar), ensuring robust performance in demanding applications. The valve's hex size is 1-1/8 inches (28.6 mm), and it requires an installation torque between 45 and 50 lbf-ft (61 and 68 Nm). With its advanced design features, the DOFCEHV is ideal for applications requiring reliable hydraulic flow control under high-pressure 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.
