The Sun Hydraulics DODPKWV (DODPKWV) is a normally open, balanced poppet switching element designed for precise hydraulic control. This valve operates by utilizing pilot pressure applied to port 3, keeping the poppet open until the pilot pressure matches the setting of the integral pilot relief stage, triggering a shift to the closed position. With its unique balanced construction, it ensures predictable switching capabilities at pressures up to 5000 psi (350 bar) at both port 1 and port 2. The valve is designed to open when pilot pressure falls below 145 psi (10 bar). It features hydraulic balancing between ports 1 and 2, with both ports fully sealed from ports 3 and 4, ensuring minimal leakage\u2014typically less than 10 drops per minute at maximum pressure. The DODPKWV model incorporates Sun's floating style construction, which minimizes internal binding risks due to installation torque or machining variations. It fits into a T-21A cavity and belongs to Series 1 with a capacity of handling up to 15 gpm (60 L/min). The valve requires a minimum pilot pressure of 400 psi (28 bar) for operation and has a maximum operating pressure rating of 5000 psi (350 bar). Installation is facilitated by its hex size of 7/8 inches (22.2 mm), requiring a torque of between 30 and 35 lbf ft (41 and 47 Nm). For maintenance, it includes an adjustment screw with an internal hex size of 5/32 inches (4 mm) and a locknut hex size of 9/16 inches (15 mm), with locknut torque specifications ranging from 80 to 90 lbf in. Compatible with Viton seal kits, this valve is suitable for applications requiring robust performance under high-pressure conditions.

This is a normally open, balanced poppet, switching element. When pilot pressure is applied to port 3, the poppet remains open until the pilot pressure reaches the setting established by the integral pilot relief stage, at which point the poppet shifts to the closed position.
- Unique balanced construction provides predictable switching with 5000 psi (350 bar) at both port 1 and port 2. When the remote pressure signal at port 3 exceeds the internal valve setting, the valve shifts to the closed position.
- Any backpressure at the drain port is directly additive to the valve setting.
- Valve will open when the pilot pressure falls below 145 psi (10 bar).
- These valves are hydraulically balanced between port 1 and port 2.
- Port 1 and port 2 are fully sealed from port 3 and port 4. Ports 3 and 4 are positively sealed.
- 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).
- 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.
