The Sun Hydraulics DKHPLBV (DKHPLBV) is a highly functional hydraulic valve featuring a normally closed, balanced poppet switching element. Designed for precise control, this valve operates under a pilot pressure system where the poppet remains closed until pilot pressure at port 3 meets the preset relief stage, causing it to shift to an open position. This mechanism ensures reliable operation and effective flow control in various applications. The valve's unique balanced construction allows for consistent performance with a maximum operating pressure of 5000 psi (350 bar) at both ports 1 and 2. It also features an integral pilot relief stage which can handle backpressure from the drain port, adding directly to the valve setting for enhanced control. The reseating of the valve occurs when the pilot pressure drops to 85% of its cracking value, ensuring stability and preventing leaks. Constructed to minimize internal part binding due to installation or cavity/cartridge variations, the DKHPLBV uses Sun\u2019s floating style construction. This design consideration extends the durability and reliability of the valve under varied operational conditions. The low leakage rate between ports 1 and 2 is less than 10 drops/min at 5000 psi, demonstrating its efficiency in maintaining system integrity. With a capacity of up to 60 gpm (240 L/min), this model can accommodate substantial flow rates making it suitable for high-demand systems. The minimum pilot pressure required to shift the valve is set at 300 psi (20 bar), providing flexibility across different hydraulic setups. For ease of installation and maintenance, it features specific dimensions for hex sizes on valves and adjustment screws as well as specified torques for secure fitting without over-tightening. Overall, Sun Hydraulics' DKHPLBV offers robust performance and precise control in hydraulic systems requiring dependable pressure management and switching capabilities.

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.
