The Sun Hydraulics DODPKAV (DODPKAV) is a normally open, balanced poppet, switching element designed to provide predictable switching under high pressure conditions. It operates with a maximum pressure of 5000 psi (350 bar) at both port 1 and port 2, making it suitable for demanding hydraulic applications. This valve features a unique balanced construction that ensures reliable operation by maintaining the poppet open until the pilot pressure at port 3 reaches a predetermined setting. Once this threshold is surpassed, the integral pilot relief stage triggers the poppet to close. The valve is designed to handle backpressure effectively, as any backpressure at the drain port adds directly to the valve setting. It will reopen when pilot pressure drops below 145 psi (10 bar). The DODPKAV's hydraulic balance between port 1 and port 2 ensures minimal leakage, typically less than 10 drops per minute at maximum pressure, enhancing efficiency and reliability in fluid control systems. The ports are fully sealed from each other, with ports 3 and 4 positively sealed to prevent cross-contamination of fluids. Sun Hydraulics has incorporated floating style construction in this model to reduce potential binding issues during installation or due to cavity machining variations. With a capacity of 15 gpm (60 L/min), this valve fits into cavity T21A and requires a minimum pilot pressure of 400 psi (28 bar) for shifting. It features an internal hex adjustment screw for easy calibration and has specific torque requirements for installation and locknut adjustments. The DODPKAV is equipped with Viton seals, ensuring compatibility with various hydraulic fluids while providing robust sealing performance in diverse operational environments.

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.
