The Sun Hydraulics DKHPLDV (DKHPLDV) is a high-performance hydraulic valve designed for precise control in fluid power applications. This normally closed, balanced poppet switching element operates effectively with a maximum operating pressure of 5000 psi (350 bar). It features an integral pilot relief stage that allows the poppet to open only when pilot pressure at port 3 reaches a pre-set level, ensuring controlled and predictable operation. The valve's unique construction minimizes leakage between ports 1 and 2 to less than 10 drops/min at 5000 psi, which translates to approximately 0.7 cc/min at 350 bar, enhancing system efficiency. The DKHPLDV supports a flow capacity up to 60 gpm (240 L/min) and requires a minimum pilot pressure of 300 psi (20 bar) to shift the valve, making it suitable for various hydraulic applications. All ports on the DKHPLDV can withstand pressures up to 5000 psi (350 bar), and the valve incorporates Sun\u2019s floating style construction which helps prevent internal parts binding due to excessive installation torque or cavity/cartridge machining variations. This feature ensures durability and long-lasting performance in demanding environments. Moreover, any backpressure at the drain port directly adds to the valve setting, offering additional operational flexibility. Designed with robustness in mind, this valve also includes specifications such as a cavity T23A, Series 3 compatibility, and utilizes Viton seals for enhanced resistance against high temperatures and chemicals. The installation torque is specified at 150-160 lbf-ft (203-217 Nm), ensuring secure mounting and operational reliability.

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.
