The Sun Hydraulics DKDPCWV (DKDPCWV) is a high-performance hydraulic valve designed for robust and precise fluid control in various applications. This normally closed, balanced poppet switching element operates efficiently under a maximum operating pressure of 5000 psi (350 bar), suitable for demanding environments. The valve features an integral pilot relief stage which determines the pilot pressure required to shift the valve, set at a minimum of 400 psi (28 bar). When this pilot pressure at port 3 is exceeded, the valve shifts to an open position, allowing fluid flow until the pressure falls to 85% of the cracking value, at which point it reseats. The DKDPCWV is engineered with unique balanced construction that ensures predictable switching and minimal leakage\u2014less than 10 drops/min at 5000 psi or approximately 0.7 cc/min at 350 bar\u2014between port 1 and port 2. All ports on this valve can withstand up to 5000 psi (350 bar), demonstrating its capability to handle high-pressure applications seamlessly. Additionally, ports are fully sealed to prevent any cross-contamination between them. This model incorporates Sun's floating style construction which minimizes potential internal parts binding due to installation torque or variations in cavity/cartridge machining, enhancing its reliability and longevity in field operations. The valve's compact form factor includes a hex size of 7/8 in. (22.2 mm) and requires an installation torque between 30-35 lbf ft (41-47 Nm), making it easy to install and maintain. Designed for versatility and efficiency in controlling fluid power, the Sun Hydraulics DKDPCWV is ideal for use in systems requiring reliable high-pressure performance with consistent operational integrity.

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.
