The Sun Hydraulics DKDPKDV (DKDPKDV) is a high-performance, normally closed, balanced poppet switching element designed for hydraulic systems. This valve operates under a unique balanced construction that allows for predictable switching at pressures up to 5000 psi (350 bar) at both port 1 and port 2. It features an integral pilot relief stage that determines the pilot pressure required to shift the valve, which remains closed until this pressure is achieved, ensuring precise control over fluid flow. The DKDPKDV supports a maximum flow capacity of 15 gpm (60 L/min) and requires a minimum pilot pressure of 400 psi (28 bar) to initiate the shift of the valve. Once shifted, the valve will reseat when the pilot pressure falls below approximately 85% of the set cracking value. This model is designed with leakage control in mind, boasting a very low leakage rate between port 1 and port 2\u2014typically less than 10 drops/min at 5000 psi (0.7 cc/min at 350 bar). Another significant feature of this model is its robust construction which incorporates Sun's floating style design, minimizing potential internal parts binding due to excessive installation torque or cavity/cartridge machining variations. All ports on this valve can withstand pressures up to 5000 psi (350 bar), and any backpressure at the drain port directly adds to the valve setting, enhancing its functionality under various operating conditions. For installation and maintenance ease, it has specified hex sizes for adjustment screw and locknut, and recommended torque settings ensure secure fitting without damage. The valve also uses Viton seals for enhanced durability against high temperatures and chemical interactions in harsh environments. Overall, the Sun Hydraulics DKDPKDV offers reliable performance with precise control suitable for demanding hydraulic applications.

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.
