The Sun Hydraulics DOFDEHN (DOFDEHN) is a normally open, balanced poppet switching element designed for precise hydraulic control. This component remains in the open position when the external vent port is blocked and shifts to the closed position when the vent port is open with sufficient pressure at port 3. It features a unique balanced construction that ensures predictable switching at pressures up to 5000 psi (350 bar) at ports 1 and 2, provided there is a minimum pilot pressure of 300 psi (20 bar). The valve incorporates an external 4 SAE vent port, which can be directly connected to a pilot switching valve with specific leakage and flow requirements. The DOFDEHN valve is hydraulically balanced between ports 1 and 2, maintaining a low leakage rate of less than 10 drops/min at high pressures. It will automatically open when pilot pressure falls below 145 psi (10 bar), ensuring reliable operation under varying conditions. All ports are capable of handling up to 5000 psi (350 bar), with ports 1 and 2 fully sealed from port 3 for enhanced performance. This valve features Sun's floating style construction, reducing the risk of internal parts binding due to excessive installation torque or machining variations. With a cavity size of T2A and series designation of 2, it offers a capacity of up to 30 gpm (120 L/min). The valve requires an installation torque between 45 - 50 lbf ft (61 - 68 Nm) and comes with a Viton seal kit for optimal sealing performance.

This is a normally open, balanced poppet, switching element. When the external vent port is blocked, the poppet remains in the open position. Venting the external port shifts it to the closed 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).
- Valve will open 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.
