The Sun Hydraulics DKHPLAV (DKHPLAV) is a high-performance hydraulic valve designed for robust fluid control in demanding applications. This normally closed, balanced poppet valve operates as a switching element with unique features that enhance its reliability and performance under high-pressure conditions up to 5000 psi (350 bar). The valve's operation is contingent on pilot pressure applied to port 3. It remains closed until the pilot pressure surpasses a pre-set threshold determined by an integral pilot relief stage, at which point the poppet shifts to an open position. This model is distinguished by its balanced construction which ensures predictable switching and stable operation across both port 1 and port 2. The design effectively seals ports 1 and 2 from ports 3 and 4, with very low leakage rates typically less than 10 drops/min at maximum pressure. Additionally, any backpressure at the drain port directly adds to the valve setting, enhancing its responsiveness and effectiveness in circuit integration. The DKHPLAV incorporates Sun's floating style construction which minimizes potential internal parts binding \u2013 a common issue due to excessive installation torque or cavity/cartridge machining variations. It supports a maximum flow capacity of 60 gpm (240 L/min) and requires a minimum pilot pressure of 300 psi (20 bar) to shift the valve. Key specifications include a maximum operating pressure of 5000 psi (350 bar), controlled pilot flow based on performance data, and precise installation requirements such as torque settings for the valve hex size of 1-1/4 in. (31.8 mm) and locknut torque between 80 \u201390 lbf\u00b7in (9\u201310 Nm). This model uses Viton seals for enhanced durability against fluid corrosiveness and temperature extremes, ensuring long service life and reduced maintenance needs in industrial hydraulic systems.

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.
