The Sun Hydraulics DKDDEHV (DKDDEHV) is a precision-engineered hydraulic valve featuring a normally closed, balanced poppet switching element. This valve operates under a unique balanced construction that ensures predictable switching actions. With the capability to handle pressures up to 5000 psi (350 bar) at ports 1 and 2, this model stands out for its high-pressure performance. The external vent port, when vented, allows the poppet to shift to an open position if there is sufficient pressure at port 3, with a minimum pilot pressure requirement of 400 psi (30 bar). This product incorporates an SAE 4 external vent port that can be directly connected to a pilot switching valve, such as Sun's model DAA solenoid pilot valve, which is recommended due to its low leakage rate and adequate pilot flow capacity. The leakage rate between ports 1 and 2 is notably low, typically less than 10 drops/min at 5000 psi (0.7 cc/min at 350 bar), enhancing system efficiency and reducing fluid loss. Additional features include Sun\u2019s floating style construction which minimizes internal parts binding\u2014a common issue in valves due to excessive installation torque or variations in cavity/cartridge machining. The DKDDEHV supports a maximum flow capacity of 15 gpm (60 L/min) and will reseat when pilot pressure falls below 145 psi (10 bar). All ports on this valve are designed to accept pressures up to 5000 psi (350 bar), ensuring versatile application across various hydraulic systems. This model is housed in a T11A cavity with Series 1 specifications and requires installation torque between 30 - 35 lbf ft (41 - 47 Nm). Sealing components within the cartridge are made of Viton for enhanced durability and leak protection under demanding conditions.

This is a normally closed, balanced poppet, switching element. When the external vent port is blocked, the poppet remains in the closed position. Venting the external port 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 external drain open and a minimum pilot pressure of 400 psi (30 bar).
- The external -4 SAE vent port may be directly connected to a pilot switching valve. The pilot valve should have a leakage rate of less than 10 drops/min (0,7 cc/min). and be able to satisfy the pilot flow requirements. Sun model DAA*-*** solenoid pilot valve is ideal for this application.
- 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 1 and port 2 are fully sealed from port 3.
- 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.
