The Sun Hydraulics DKDRXHV (DKDRXHV) is a high-performance hydraulic switching element designed for precise fluid control in various applications. This normally closed, balanced poppet valve operates effectively with a unique construction that allows for predictable switching. It functions by maintaining the poppet in a closed position when the vent port (port 4) is blocked and shifts to an open position upon venting, requiring a minimum pilot pressure of 400 psi at port 3. The DKDRXHV features an impressive operating pressure capacity of up to 5000 psi at ports 1 and 2, with very low leakage rates\u2014typically less than 10 drops per minute at maximum pressure. This ensures efficient and reliable performance in systems requiring stringent leakage control. The valve reseats when pilot pressure falls below 145 psi, adding to its operational safety and efficiency. For installation flexibility, port 4 can be externally connected to a pilot switching valve like the recommended Sun model DAA solenoid pilot valve, which matches the leakage and flow requirements of the DKDRXHV. Additionally, all ports on this valve are designed to accept pressures up to 5000 psi, and it incorporates Sun\u2019s floating style construction which minimizes internal parts binding due to installation or machining variations. This valve is housed in a T21A cavity and can support up to 15 gpm flow capacity. It's built for easy installation with a hex size of 7/8 inches and an advised torque range of 30 - 35 lbf ft. The compact model weighs about .35 lb, making it suitable for various setups without adding significant weight or bulk. With its robust design and precise control capabilities, the DKDRXHV is ideal for applications needing reliable hydraulic flow management under high-pressure 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.
