The Sun Hydraulics DKFDEHV (DKFDEHV) is a highly efficient hydraulic valve featuring a normally closed, balanced poppet switching element. This valve operates by maintaining the poppet in a closed position until the external vent port is vented, allowing it to shift to an open position when there is adequate pressure at port 3. It is designed for robust performance with a maximum operating pressure of 5000 psi (350 bar) at both port 1 and port 2, and requires a minimum pilot pressure of 300 psi (20 bar) to shift the valve. Its unique balanced construction ensures predictable switching and minimal leakage\u2014less than 10 drops/min at 5000 psi\u2014enhancing system reliability and efficiency. The external SAE vent port can be directly connected to a pilot switching valve, such as the recommended Sun model DAA solenoid pilot valve, which should have minimal leakage to meet the pilot flow requirements. The DKFDEHV incorporates Sun's floating style construction which minimizes potential internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This feature contributes to its durability and consistent performance. All ports on this valve are capable of handling up to 5000 psi (350 bar), with ports 1 and 2 fully sealed from port 3. This model fits in a T2A cavity, supports a flow capacity of up to 30 gpm (120 L/min), and has specific installation torque requirements ranging from 45-50 lbf\u00b7ft (61-68 Nm). The valve also uses Viton seals for enhanced chemical resistance and durability under various operating conditions. This makes the DKFDEHV an ideal choice for applications requiring reliable high-pressure performance and precise control in hydraulic systems.

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 port 1 and port 2, with the external drain port open and a minimum pilot pressure of 300 psi (20 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.
