The Sun Hydraulics DOHCEHV (DOHCEHV) is a normally open, balanced poppet switching element designed to provide reliable hydraulic control in demanding applications. This valve features a unique balanced construction that ensures predictable switching with pressures up to 5000 psi (350 bar) at both ports 1 and 2, while requiring a minimum pilot pressure of 300 psi (20 bar) for operation. The valve is hydraulically balanced between port 1 and port 2, with a very low leakage rate of less than 10 drops per minute at maximum pressure. It opens when the pilot pressure falls below 145 psi (10 bar), making it suitable for various hydraulic systems. The DOHCEHV can be configured with either an external atmospheric vent (X control) or static external drain (E control). The X control configuration allows the valve to be atmospherically referenced, offering solutions for existing circuits using non-vented valves. For new applications, four-port valves are recommended due to potential external leakage over time. The valve's design incorporates Sun's floating style construction to minimize internal part binding caused by excessive installation torque or machining variations. This model fits into cavity T17A and belongs to series 3, with a capacity of up to 60 gpm (240 L/min). It requires a hex size of 1\u00bc inches (31.8 mm) and an installation torque between 150 to 160 lbf ft (203 to 217 Nm). The Sun Hydraulics DOHCEHV is equipped with Viton seal kits for durability and compatibility with various hydraulic fluids. This versatile switching element is ideal for applications requiring precise fluid 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.
