The Sun Hydraulics DKHPLWV (DKHPLWV) is a high-performance hydraulic valve designed for precise control in fluid power applications. This normally closed, balanced poppet valve operates as a switching element with unique characteristics that enhance both functionality and reliability. The valve remains closed under pilot pressure until it reaches a pre-set threshold determined by an integrated pilot relief stage, at which point it shifts to an open position. This feature allows for predictable switching behavior under high-pressure conditions, up to 5000 psi (350 bar) at both port 1 and port 2. The DKHPLWV is engineered to handle a maximum flow rate of 60 gpm (240 L/min) and requires a minimum pilot pressure of 300 psi (20 bar) to shift the valve. It supports maximum operating pressures up to 5000 psi (350 bar), making it suitable for robust industrial applications. The design incorporates Sun's floating style construction which minimizes the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This valve also features low leakage rates, typically less than 10 drops/min at 5000 psi, ensuring efficient operation and minimal fluid loss. All ports on the DKHPLWV can accept pressures up to 5000 psi (350 bar), and any backpressure at the drain port directly adds to the valve setting, enhancing its performance stability. Additionally, ports are designed with positive sealing between port 1 and port 2 as well as between ports 3 and 4, which prevents cross-contamination between different channels within the system. With a robust construction and precise control capabilities, the Sun Hydraulics DKHPLWV is ideal for applications requiring reliable high-pressure performance and predictable operational behavior.

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.
