The Sun Hydraulics DKHRXHV (DKHRXHV) is a high-performance hydraulic valve designed for precise control in fluid power applications. This model, part of the T23A cavity series, is a normally closed, balanced poppet switching element that operates effectively with a maximum capacity of 60 gpm (240 L/min). The valve features unique balanced construction which ensures predictable switching behavior and can handle up to 5000 psi (350 bar) at ports 1 and 2 when the vent port (port 4) is open, with a minimum pilot pressure of 400 psi (30 bar) at port 3. The design ensures that ports 1 and 2 are completely sealed from ports 3 and 4, which are positively sealed themselves. This configuration minimizes leakage between port 1 and port 2 to less than 10 drops/min at maximum pressure conditions. Additionally, the valve will reseat itself when pilot pressure falls below 145 psi (10 bar), enhancing its reliability in varying operational conditions. For optimal performance, port 4 can be externally connected to a pilot switching valve such as the Sun model DAA solenoid pilot valve, which matches the leakage specifications and satisfies pilot flow requirements. The DKHRXHV also incorporates Sun\u2019s floating style construction to avoid internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. This model is engineered for robustness with a maximum operating pressure capacity of up to 5000 psi (350 bar), making it suitable for demanding hydraulic systems where high flow and pressure control are necessary. The valve's hex size is set at 1-1/4 inches (31.8 mm), with an installation torque range from 150 to160 lbf-ft (203 to217 Nm), and it weighs approximately 1.20 lbs (0.55 kg). Seals made from Viton ensure durability against various fluids and operating 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.
