The Sun Hydraulics DKDDEHN (DKDDEHN) is a high-performance hydraulic valve designed for advanced fluid control applications. This normally closed, balanced poppet switching element operates effectively by maintaining the poppet in a closed position when the external vent port is blocked. Upon venting the external port, and with adequate pressure at port 3, the valve shifts to an open position. It features unique construction that supports predictable switching at pressures up to 5000 psi (350 bar) across ports 1 and 2 when the external drain is open and with a minimum pilot pressure of 400 psi (30 bar). The DKDDEHN valve includes an external SAE 4 vent port that can be directly connected to a pilot switching valve, such as the recommended Sun model DAA solenoid pilot valve. This setup ensures minimal leakage\u2014less than 10 drops per minute at 5000 psi\u2014between ports 1 and 2. The valve will reseat when pilot pressure drops below 145 psi (10 bar), ensuring efficient operation under varying pressures. All ports on this valve can withstand up to 5000 psi (350 bar), making it suitable for robust applications. The design incorporates Sun's floating style construction which minimizes internal parts binding due to installation torque or machining variations of cavity/cartridge. This feature enhances reliability and longevity of the valve in demanding operational conditions. Additionally, the DKDDEHN fits within a T11A cavity and is part of Sun Hydraulics\u2019 Series 1. It can handle a flow capacity of up to 15 gpm (60 L/min) and requires specific installation torque between 30-35 lbf ft (41-47 Nm). The seal kit for this cartridge utilizes Viton components, ensuring durable sealing under high-pressure 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.
