The Sun Hydraulics DKDPCBV (DKDPCBV) is a high-performance hydraulic valve designed for robust and efficient control in hydraulic systems. This normally closed, balanced poppet, switching element operates effectively under high pressure conditions up to 5000 psi or 350 bar. It features a unique balanced construction that ensures predictable switching performance between port 1 and port 2, while maintaining complete isolation from ports 3 and 4. The valve only shifts to an open state when the pilot pressure at port 3 exceeds the preset value determined by the integral pilot relief stage. Equipped to handle a flow capacity of up to 15 gpm or approximately 60 L/min, the DKDPCBV is suitable for a wide range of fluid power applications. The minimal leakage rate enhances system efficiency, typically less than 10 drops per minute at maximum operating pressure, which translates to about 0.7 cc/min at 350 bar. This model also incorporates Sun\u2019s floating style construction which minimizes potential internal part binding due to excessive installation torque or variations in cavity/cartridge machining. For installation and adjustments, the valve features a hex size of 7/8 inches (22.2 mm) and requires an installation torque between 30 - 35 lbf ft (41 -47 Nm). The adjustment screw has an internal hex size of 5/32 inches (4 mm), ensuring precise control over operational settings. Additionally, it includes a locknut with a hex size of 9/16 inches (15 mm) and recommended torque setting of between 80 -90 lbf in (9 -10 Nm). This model is compatible with Viton seal kits for enhanced durability and resistance against various fluids.

This is a normally closed, balanced poppet, switching element. When pilot pressure is applied to port 3, the poppet remains closed until the pilot pressure reaches the setting established by the integral pilot relief stage, at which point the poppet shifts to the open 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 open position.
- Any backpressure at the drain port is directly additive to the valve setting.
- Valve will reseat when the pilot pressure falls to 85% of the cracking value.
- 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.
