The Sun Hydraulics DKDRXHN (DKDRXHN) is a high-performance hydraulic valve designed for advanced fluid power applications. This model features a normally closed, balanced poppet switching element that operates effectively under a maximum operating pressure of 5000 psi (350 bar). The valve's unique construction ensures predictable switching and low leakage rates, typically less than 10 drops/min at maximum pressure, enhancing system reliability and performance. This valve is engineered with precision to maintain separation between flow ports and control ports, ensuring no cross-contamination of hydraulic circuits. The DKDRXHN can handle a flow capacity of up to 15 gpm (60 L/min), making it suitable for various industrial applications requiring robust fluid control. It incorporates Sun's floating style construction which minimizes the risk of internal parts binding due to installation torque or cavity/cartridge machining variations. For operation, the valve remains closed when the vent port (port 4) is blocked and shifts to an open position when this port is vented, provided there is sufficient pilot pressure at port 3 (minimum 400 psi/28 bar). It will reseat when pilot pressure falls below 145 psi (10 bar). Additionally, the design allows for external connection of port 4 to a pilot switching valve to further enhance control flexibility. The DKDRXHN's compact size (.35 lb/0.15 kg) and specific installation requirements (torque settings between 30-35 lbf ft/41-47 Nm) facilitate easy integration into existing systems without extensive modifications. Each component, including the seal kit with Viton: 990021006 specifications, underscores Sun Hydraulics' commitment to durability and quality in demanding operational conditions.

This is a normally closed, balanced poppet, switching element. When the vent port (port 4) is blocked, the poppet remains in the closed position. Venting port 4 shifts it to the open position, provided there is sufficient pressure at port 3.
- Unique balanced construction provides predictable switching with 5000 psi (350 bar) at both ports 1 and 2, with the vent (port 4) open and a minimum pilot pressure of 400 psi (30 bar) at port 3.
- 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).
- Valve will reseat when the pilot pressure falls below 145 psi (10 bar).
- Port 4 may be externally connected to a pilot switching valve. The pilot valve should have a leakage rate of less than 10 drops/min. and be able to satisfy the pilot flow requirements. Sun model DAA*-*** solenoid pilot valve is ideal for this application.
- 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.
