The Sun Hydraulics DKHDEHV (DKHDEHV) is a sophisticated hydraulic valve designed for precise control in fluid power 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. Activation occurs when the external port is vented, allowing the valve to shift to an open state if there's adequate pressure at port 3. Key features of the DKHDEHV include its unique balanced construction which ensures predictable switching between ports. The valve can handle up to 5000 psi (350 bar) at both port 1 and port 2 when the external drain port is open, with a minimum pilot pressure requirement of 300 psi (20 bar). It also incorporates a leakage rate of less than 10 drops/min at these pressures, ensuring efficient operation with minimal fluid loss. Designed for high-capacity systems, it supports up to 60 gpm (240 L/min) and can withstand maximum operating pressures up to 5000 psi (350 bar). The DKHDEHV uses a T17A cavity and belongs to Series 3, indicating its compatibility with specific system requirements. Additionally, its construction includes Sun's floating style design which minimizes internal parts binding\u2014a common issue due to excessive installation torque or variations in cavity/cartridge machining. For optimal performance, this valve should be paired with a pilot valve like the Sun model DAA solenoid pilot valve that meets stringent leakage and flow requirements. The external SAE vent port facilitates direct connection to such pilot switching valves, enhancing its functionality in complex 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.
- These valves are hydraulically balanced between port 1 and port 2.
- 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).
- 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.
