The Sun Hydraulics DKHRXHN (DKHRXHN) is a high-performance hydraulic valve designed for advanced fluid power applications. This model is a normally closed, balanced poppet switching element that operates effectively under high pressure conditions. The valve features a unique balanced construction that ensures predictable switching at pressures up to 5000 psi (350 bar) at both ports 1 and 2 when the vent port 4 is open, with a minimum pilot pressure of 400 psi (30 bar) required at port 3. The DKHRXHN 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 design enhances the reliability and longevity of the valve in demanding operational environments. The valve has a very low leakage rate between ports 1 and 2, typically less than 10 drops/min at 5000 psi (0.7 cc/min at 350 bar), which is crucial for maintaining system efficiency and performance. Port configurations in the DKHRXHN are optimally sealed, with ports 1 and 2 fully isolated from ports 3 and 4 to prevent any cross-contamination or leakage. The valve will automatically reseat once the pilot pressure drops below 145 psi (10 bar). For external connection, port 4 can be linked to a pilot switching valve like the Sun model DAA solenoid pilot valve, which matches the DKHRXHN's performance specifications. This model is housed in a T23A cavity, belongs to series 3, and can handle up to 60 gpm (240 L/min) capacity. It supports a maximum operating pressure of up to 5000 psi (350 bar), making it suitable for high-pressure applications across various hydraulic systems. Installation requires specific torque settings ranging from 150 to160 lbf-ft (203 to217 Nm) and the unit weighs approximately1.20 lb(0.55 kg). The recommended seal kit for this cartridge is Viton:990023006.

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.
