The Sun Hydraulics DOHCXHV (DOHCXHV) is a normally open, balanced poppet, switching element designed for precise hydraulic control. This valve operates with pilot pressure at port 3 to shift the valve to the closed position, utilizing a unique balanced construction that ensures predictable switching capabilities at pressures up to 5000 psi (350 bar) across ports 1 and 2. The valve requires a minimum pilot pressure of 300 psi (20 bar) to shift and will open when the pilot pressure drops below 145 psi (10 bar). It features a very low leakage rate between ports 1 and 2, typically less than 10 drops per minute at maximum pressure. The DOHCXHV is hydraulically balanced between its primary ports, offering versatility in various applications. It is available in two configurations: external atmospheric vent (X control) or static external drain (E control). The X control configuration provides an atmospheric reference, making it suitable for addressing issues in circuits using non-vented valves. For new applications or where moisture ingress is a concern, the four-port configuration or connecting the vent port to drain with the E control option is recommended. This three-port balanced logic valve utilizes the same cavity as unbalanced logic valves of similar size, allowing it to serve as a functional replacement. It incorporates Sun's floating style construction to minimize internal component binding due to installation torque variations. The DOHCXHV fits into cavity T-17A and belongs to series 3, with a capacity of up to 60 gpm (240 L/min). Its compact design includes a hex size of 1\u00bc inches (31.8 mm) and requires an installation torque of 150-160 lbf ft (203-217 Nm). The valve's robust Viton seal kit ensures reliable performance under demanding 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.
