The Sun Hydraulics DODPKBV (DODPKBV) is a normally open, balanced poppet switching element designed for precise hydraulic control. It features a unique balanced construction that ensures predictable switching at pressures of up to 5000 psi (350 bar) at both port 1 and port 2. The valve operates by remaining open until the pilot pressure applied to port 3 reaches the setting established by the integral pilot relief stage, at which point it shifts to the closed position. This product is particularly useful in applications requiring reliable pressure control, as it will reopen when the pilot pressure falls below 145 psi (10 bar). The valve is hydraulically balanced between port 1 and port 2, with ports 3 and 4 being positively sealed from each other, ensuring minimal leakage\u2014typically less than 10 drops per minute at maximum pressure. The DODPKBV also incorporates Sun's floating style construction to minimize internal part binding due to excessive installation torque or machining variations in cavity/cartridge setups. It fits into a T21A cavity and belongs to series 1 with a capacity of up to 15 gpm (60 L/min). For proper operation, a minimum pilot pressure of 400 psi (28 bar) is required to shift the valve. Additionally, it features a valve hex size of 7/8 in. (22.2 mm) and an installation torque range of 30-35 lbf ft (41-47 Nm). The adjustment screw has an internal hex size of 5/32 in. (4 mm), while the locknut hex size is 9/16 in. (15 mm), requiring a locknut torque of between 80-90 lbf in. (9-10 Nm). This robust design makes it suitable for demanding hydraulic systems requiring efficient switching elements with low leakage rates and high-pressure capabilities.

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.
